Note: The Timbren Axle-Less suspension system may require additional support on your trailer. If your trailer does not have a crossmember above the spot where you want to install the Timbren system, you may need to reinforce the frame. You can accomplish this three ways. First, you can retrofit the trailer with a crossmember. Second, you can build out the trailer frame. Third, you can use 2" x 3" steel tubing to connect the 2 Timbren suspensions together using the built-in hole on each unit.


Ground Clearance

Ride on rubber with Timbren's Axle-Less trailer suspension system. This one-of-a-kind suspension consists of two separate units, each containing rugged steel arms and two strong, hollow rubber springs. Overall, the system safely and effectively absorbs road shock, minimizes trailer bounce and rattle - regardless of load size - and helps to protect your trailer's components and cargo. Built-in camber and toe-in keep your trailer tracking straight to minimize tire wear. Integrated hangers attach to your trailer's frame. And 2" x 3" holes make it easy to reinforce your trailer's frame by adding steel tubing (if needed).


The Axle-Less independent suspension system replaces your trailer's existing leaf spring suspension and can eliminate the need for an axle. The independent action of the suspension reduces roll when your trailer is cornering and allows you to maximize ground clearance and minimize deck height. Your trailer can have the same side-to-side clearance as your tow vehicle.


Because you're riding on rubber, your trailer will ride smoothly and comfortably, whether you're navigating rocky terrain or highway asphalt.


Timbren Axle-Less Suspension Parts

Components

  1. The AEON progressive-rate main spring supports the weight of your trailer and cargo and easily absorbs road shock. It is constructed of heavy-duty, hollow rubber.
  2. The rebound spring minimizes trailer bounce, rattle and bottoming out. It keeps the suspension under constant tension and ensures that the main spring compresses and expands in a controlled fashion. And it delivers a smooth, stable ride - regardless of how much cargo is on the trailer.
  3. The trailing arm and integrated hanger attach the suspension to the side and bottom of the trailer frame.
  4. The control arm carries the spindle and the hub. It pivots on strong, long-lasting urethane bushings that never require lubrication.
  5. The EZ lube, 4" lift spindle (straight model shown) is simple to grease. If damaged, it can be removed and replaced, saving you both time and money.
  6. The hub is not included with this model.
  7. The built-in hole accepts 2" x 3" tubing. If there is no crossmember above the suspension, you can easily add support to your trailer's frame by inserting 2" x 3" steel tubing through the hole on each suspension unit and then bolting the tubing into place.

Timbren Axle-Less Suspension versus Leaf Springs

Leaf Spring Example

The Axle-Less suspension's progressive spring is a definitive upgrade over leaf springs. Although leaf springs deliver a stable ride when supporting a load, a trailer with leaf springs will bounce and rattle when it's empty or supporting a light or off-center load. On the other hand, your trailer can bottom out on bumpy roads if the load is too heavy. The AEON progressive-rate springs of the Axle-Less suspension always deliver the same reliable performance, no matter the load size. As more weight is added to the trailer, the springs compress and become stiffer, offering more support for heavy loads. And because they rebound more slowly than leaf springs, the AEON springs do a better job of absorbing road shock, thereby keeping your trailer from bouncing and rattling when you're carrying a light load. So with this versatile system you will enjoy a smooth ride whether you're towing an empty trailer or a hefty load.


Unlike leaf springs, Timbren's Axle-Less suspension units operate independently of one another. Each spring activates only when needed. This reduces roll and delivers top-notch performance, even when you're hauling off-center loads. When your trailer with leaf springs takes a turn, one side of the suspension compresses and takes on more weight, and the other side becomes looser and bounces. This causes rattle and can make the trailer lean to one side. But when your trailer with the Axle-Less suspension takes a turn, one side compresses and becomes more rigid to absorb the weight, and the other side expands to normal height to help steady the load and minimize bounce and rattle. The load stays better balanced, even if it is off-center.


Timbren Axle-Less Suspension versus Torsion Axles

Torsion Axle Example

Timbren's Axle-Less trailer suspension system is a great alternative to torsion axles. While both systems allow either side of the trailer's suspension to operate independently, only Axle-Less suspensions are actually separate units. Torsion axles still require a bar that spans the bottom of your trailer, whereas Timbren's system can eliminate the need for a thru axle - giving you the same amount of ground clearance from the front of your trailer to the rear. It also allows Axle-Less suspensions to fit any trailer width - unlike torsion axles, which have to be fitted to an exact frame width.


Axle-Less suspensions operate in a smoother, less stressful manner than torsion axles. Torsion axles use a twisting motion, where the bar inside the axle tube rolls against rubber cords or a rubber wall to create compression and resistance. The up-and-down motion of the main spring and the side-to-side motion of the rebound spring in Timbren's Axle-Less suspension work together to provide smooth, consistent compression - with no twisting - that results in a better ride and less stress on the suspension's components.


Installing the Timbren Axle-Less Suspension

Whether you are building a trailer or retrofitting your existing trailer with the Axle-Less system, you must make certain that the trailer's frame is both perfectly square and sturdy enough to support a heavy load without the aid of a thru axle.


Install Option 1

There are three ways to install the Axle-Less suspension. The easiest method, which is recommended if you are replacing axles on your trailer, is to install a piece of 2-inch x 3-inch rectangular tubing (sold separately - available at most weld shops) through the integrated hole in the Axle-Less suspension. Then all you need to do is bolt the suspension to the side of the trailer's frame with three bolts (not included).


Install Option 2

The second option for installation is to fabricate an inboard extension plate that attaches the trailer's frame to the Axle-Less suspension.


Install Option 3

The third method of installation is to bolt the Axle-Less suspension's hanger to the trailer's frame and to an existing crossmember that is in the area where you want to install the suspension.


With both the second and third options, you must use three bolts to attach the suspension to the side of the frame. And you also have to use two or three bolts to attach the suspension to the bottom of the frame extension, or crossmember. Both the second and third methods of installation will eliminate the need for a thru axle and provide the most clearance.


Measuring Diagram

Timbren's Axle-Less suspension units should be installed directly across from one another. Before mounting the units, measure back from the coupler and mark the frame to make sure that the two distance measurements (A and B) are within 1/8 inch of each other. Then you can drill holes through the frame and attach the hangers with Grade-5, half-inch bolts (not included).

Video Transcript for Timbren Trailer Axles - Rubber Spring Suspension - TASR5200S03 Review

Speaker 1: Today, we're gonna take a look at the Timbren axle-less trailer suspension system with the 4" lift easy lube spindles, no hubs, and a 5200 pound weight capacity. Now this suspension system will provide a nice safe, smooth, quiet ride for your trailer. It's two separate units that will replace your existing axle. If you notice on these, they use the Aeon progressive rate mainsprings right here to help absorb road shock, support your trailer's load, delivers a nice smooth, stable ride, regardless of the load size. They will compress and become stiffer as the load increases, boosting your spring's strength. The rebound springs, which are right back here, will act as a return device to minimize rattle and bottoming out.

They'll create constant pressure on the arm so the suspension is never completely relaxed. These are two independent units. They can eliminate the need for a through axle. They will increase ground clearance, gives you a lower deck height for easy loading and unloading, helps reduce roll during cornering, and it'll fit any trailer width. It has built in camber and tow-in to help your trailer to track straight, reducing wear on your tires.If you notice on the spindles, it's a 4" lift easy lube spindle, which will accept trailer hubs that we do sell separately.

It will work with the Dexter 2600 pound hubs, part number A-201-5UC3-EZ or the 8-213-5UC1-EZ. Both of those hubs will work on this and we do list those on our website and they are sold separately. The 4" lift on this will provide maximum ground clearance and the spindles can be easily removed from the units for simple replacement if they are damaged and if you notice, they also have the 5 bolt brake mounting flange on them. These are a heavy duty steel construction. They have a nice black powder coat finish on them to help resist wear and corrosion.

They are very easy to install on a line. They can be bolted on or welded to your trailer's frame. Again, the specs on this, these are designed to fit one axle and two axle trailers that use regular tires. They are not recommended for triple axle trailers. The weight capacity on these is 5200 pounds.Now on the spindle and the hub, the compatibility, the bearings they use, the inner would be part number 25580 and the outer would be either 515123 or LM67048 and the seal that's used on these has a diameter of 2.25" and it does include, if you notice right here, the spindle nuts, washers, and the cotter pins.

But that should do it for the review on the Timbren axle-less trailer suspension system with the 4" lift easy lube axles, no hubs, and a 5200 pound weight capacity.

I installed these on a small jeep style camping trailer that I built. I plated my frame and also used the suggested two inch square tubing to tie them together. It rides very well, looks like it should be very durable, it's a simple design, simple to install, more economical than other independent systems, has less parts to go bad than other systems, I would highly recommend to any body using a trailer on rough roads! 582196

Only been driving around on the axle-less system for about a week now and it has far exceeded expectations. I get better gas mileage, my trailer now sits like it was intended to, my trailer doesn't bounce like it used to, I wouldn't trade this axle system for any other. Just wish I would have known which outboard assembly arm my trailer needed with the axle-less system before I placed my order. Still not a problem though, plan on using the wrong outboard arm to build a different trailer. So far, a great product! 208571

Review from a similar Timbren Axle-Less in Trailer Leaf Spring Suspension


Timbren Axle-Less Suspension - Spindle Only - Regular Tires - 5200 lbs Item # ASR5200S01 Looks great on empty trailer, idea is good, bad execution. When loaded tires "splay out" severely, excessive tire wear, obviously too much play in system somewhere. 584361


Comments
Excessive camber which causes wear on the portion of the tire tread closest to the trailer can be caused by a few different things. 1 The axle-less suspension system has a 5200 lb per set capacity, so youll want to be sure this amount is not being exceeded. 2 The surface of the trailer that the suspension member is added to needs to be an integral part of the trailer that should have NO give in it whatsoever. Any flexing of the side member there will throw off the camber of the tires. I have seen what you describe occur when the suspension system has been mounted to tubular steel that made up the edge of the trailer frame. In that instance, some angle iron was added to stiffen things up. 3 Its not required, but a piece of 2x3 inch tube steel of the appropriate length can be used as a beam connecting the two sides, utilizing the existing hole in the axle-less suspension member. This will help stiffen things up. 4 The suspension system should have included some shims that can be used where the spindle attaches to the suspension portion of the assembly. Using these shims can decrease the camber, but only if the points mentioned above are taken care of. Ive checked with Timbren regarding the above, and they concur.

I was amazed at the attention given to me and my order. I was kept up to date untill my order arrived, it also arrived a few days before the expected time. The axle less system looks to be so much easier to install and more functional than the regular spring suspension. If compared by cost and labor to the other spring system, I find that this is considerably less. I have yet to install it, but will send photo of finished product as soon as possible. 178367

Review from a similar Timbren Axle-Less in Trailer Leaf Spring Suspension


Purchased 2 sets of the Timbren 1200 Axle-less systems for upgrading the suspension on an older 30' ft glider trailer. Single axle with small (13") tires made towing tough due to porpoising, dragging on drive entrances do to poor flotation; also German made and metric, no repair parts. GVW 2000 lbs equated to bouncy ride. Dual sets now allow the trailer to ride over bumps and sharp inclines easily, smoothly, little bounce on country roads; porpoising is history. My glider now rides securely, safely, quietly. Install time 4 1/2 hours (includes head-scratching). Results are outstanding, units are totally solid. Recommend the square tube interconnect, easy and quick - trailer frame was on the light side, so a precautionary fix. Clean look underneath. Ordered 5 wheels w/tires, very nice. Helpful neighbor so impressed he ordered a HD single set for his new DIY snowmobile trailer. Customer satisfaction 100%, from phone order, online support, product information, immediate shipping, install instructions, followup... HIGHLY RECOMMENDED! 580744


Comments
I have just a little more to add regarding my purchase: Two sets, of the Timbren Axle-less assemblies, 1200 lb, and 5 wheels. I placed the order via phone, and whoever was on-call that day provided great answers and recommendations regarding the units, wheels and tires. At 31 feet, the trailer originally exhibited amplified porpoising on any bumps or dips in the road. Also bouncing and occasional sideways tipping due to the single axle. It made a lot of noise on my mountain community washboards. I speculated that the Timbren units would solve most, if not all of these problems and they have. Installation on my older 31 ft European ie, metric and no longer manufactured glider trailer was a mere 4.5 hours from removal of the old single axle to setting the trailer back down on its new assemblies. Instructions are complete, precise, useful and helpful. Appreciated. Little to comment on as installation was all straight-forward. I would like to describe the maiden voyage to the airport and back, but there is nothing to tell, other than it towed beautifully proper alignment instructions, and all that I viewed from the rear view mirror looked like a magic carpet ride. It rides over washboards and pot holes like a marathon hurdler, the 4-wheel independent suspension is great. Packaging: the shipping boxes all arrived in good condition, but the cardboard component boxes inside them... not so much. Most were ripped and open due to heavy components lightly surrounded with brown packing paper, just token amounts. Parts: all was accounted for minus a pair of spindle axle washers for one set, easily replaced at the local farm and ranch supply. No squawk, just an fyi. I am very pleased with your product and support, and was happy to leave a 5-star review with photos. The upgraded suspension was also a topic this past weekend at the glider port by those who regularly trailer their ships to various soaring events, some as far as a thousand miles away. My compliments to eTrailers, hope you can use my info,

A little bit pricey, at first. But in the long run they are cheaper. We used to bend or break an axle every 3 or 4 months. But we have had these a couple of years now with no problems. One thing that is nice is on a tandem axle set up you can get a flat and you just have to take the wheel off and run on 3 or 2 wheels without the hubs hitting the ground. 593458

Review from a similar Timbren Axle-Less in Trailer Leaf Spring Suspension


This is my favorite suspension system in all the world! Rides like an absolute dream. Easy to set up and install. Works on any trailer frame size. One thing to know: You don't get the ride height you get with a standard leaf spring suspension. Even with 15-inch wheels, the ride height is pretty low - maybe 10-12 inches of ground clearance to the bottom of the main trailer frame. If you need more ride height, get the lifted version. A few areas of possible improvement? It's difficult to bolt the suspension unit to a crossmember using the middle bolted hole, which uses a tacked-on weld nut. You have zero room for error when drilling the hole through your cross member, and you can't really use the suspension as a template. Hmmm ... also, the hanger plate mounting holes are positioned 1-inch from the bottom of the trailer frame. That makes it very difficult, since I use channel side rails, to use standard 1/2-inch USS or SAE washers on the backside. There isn't room. Just an extra 1/4 of a inch would allow me to use standard washers underneath the nuts on a channel frame. Nitpicking aside, it's amazing. 410020

Excellent, helpful customer service sold me this product, and trust me when I say it's worth the price tag. Pulled the old axle and leaf spring off a 60's era Bantam and swapped out for this with a support bar in between. Bumped up tires to 315/75r16 BFG TA/KO's to match my rig and am amazed at how much better this trailer now pulls. Empty it wad bouncing all over the place with the old axle and leaf spring setup. Now I hardly even know it's there. Was very easy to install, took a couple hours but I am happy with how it turned out. A+++ product and customer service! 172019

They are GREAT! I put them on a small offroad trailer that has followed me all over some really rough roads in remote Oregon, Washington, and Idaho. They have performed flawlessly, helped the trailer tow extremely well, and were the single best upgrade I did to that trailer. Very much looking forward to another summer of exploring! Massive upgrade to the stock axle leaf spring combo, and I have had the opportunity to show it off to alot of fellow overlanders. I cant speak high enough of them. I also purchased a set of airbags for my vehicle which unfortunately have not held up terribly well. I have had to field repair one once already, and neither holds air terribly well. Truth be told they seem very underdesigned for the job they perform. From my super secret high tech pocket internet window.

It looks like a wonderful, well built system. The shipment was partial, turns out they forgot the rest. Customer service corrected the matter, still took almost 2 additional weeks to get the rest. The packaging for shipping - The suspension pieces should be packed individually not together. The box was torn in half and falling out, scratched up like it had fallen out of the box during shipping when it arrived. There were no installation / alignment shims or mounting hardware in the box, don't know if they were included and missing or they forgot that as well. I found no information on the paperwork for the inventory expected to be in the box. 424016

Review from a similar Timbren Axle-Less in Trailer Leaf Spring Suspension


I think their axle-less design is very clever. The build quality of the suspension part looks good. I have heartburn over the spindle build quality. The spindle is mounted to the suspension and then the trailer wheel mounts on the spindle. The spindles I received are warped from welding. The plate that bolts onto the suspension does not mount flat due to this warping. I called Timbren. The gentleman that helped me was very pleasant. I described the problems and he said he would check his inventory and call me back. He did call me back and said they are all like that. He said get out the grinder and fix what you can and just tighten the bolts super tight, maybe the gap will go away. Really? Wow. The other problems are a LOT of weld spatter where the bolts are supposed to fit and they made a bend in the plate too close to the bolt holes so two bolt heads hit the bend and dont fit flat against the part they are supposed to hold together. Yikes! I am taking the spindles to a machine shop to fix them but I would not have ordered this Timbren stuff had I been warned before hand. So, fair warning. 100490


Comments
Your comments regarding the Axle-Less Suspension are greatly appreciated. To address the issues you have pointed out, we have carefully reviewed our assembly. While we did not come across any major issues, we did however discover a few areas where the quality could be improved, specifically in the areas you brought to our attention. The following improvements have been made to improve the manufacturing process: - Robotic welder gun re-programmed so that it stops from getting too close to the areas adjacent to the mounting holes of the outboard arm and control arm. This will minimize weld spatter. - The distortion of the flat plates is due to the high degree of heat generated during welding. We conducted experiments, changing the sequence of welding operations until we were successful in minimizing the distortion. We apologize if our customer service in addressing your concerns was insufficient at the time of your phone call. Timbren is an ISO 9001:2008 company with an excellent reputation for providing customers with quality products that are well-performing and easy to install.

Ask the Experts about this Timbren Trailer Leaf Spring Suspension

  • Should 3,500 lb or 5,200 lb Timbren Axle-Less System be Used for over 3,600 lbs of Loaded Trailer
    Since your axle will ultimately be under the weight of your trailer and it's contents you definitely need to make sure that it is rated for more than what you will be carrying. You need to go with the 5,200 lb weight capacity. For this we have the Straight Spindle # ASR5200S01, 4" Lift Spindle # TASR5200S03, and 4" Drop Spindle # ASR5200S04. This is compatible with the idler hub # 8-213-5UC1-EZ or the hub and drum assembly # 8-201-5UC3-EZ. I recommend going with the hub and drum assembly...

  • Recommended Replacement Axles for Old Dexter Axle #11 5,200 lb Torsion Axles
    I reached out to my contact at Dexter Axle who said that based off of the numbers you sent in it sounds like you have a #11 Torsion axle rated for 5,200 lbs that is on a Haulmark Trailer manufactured back in 2001 (at least the axle was). Your axle should use 6 lug hubs with EZ-Lube spindles and that it has a 95" hub-face measurement with a 75-3/4" outside bracket measurement (which would be equivalent to spring-center). The closest thing that we have to this is the Dexter Trailer Axle...

  • Can 3,500 lb Axles be Changed to 5,200 lb Axles and Parts Needed
    The short answer is yes, you can replace your 3,500 lb axle with a 5,200 lb axle. The longer answer is that while you can change to a higher-rated axle, that does not mean your trailer has a higher weight capacity. The reason is, weight ratings are determined by the lowest-rated component, which can be something other than the axle, like the trailer chassis, for example. So you would need to ensure via the trailer manufacturer what the lowest-rated component is. With that said, in order...

  • How to Raise a 2005 Jayco Jay Feather 18F
    I do have an option for you but there would be no way to lift your trailer using your existing half torsion axle system as they just don't make anything to allow for this. The only option you have to raise the trailer would be to install a new system with built-in lift like the Timbren Axle-Less Trailer Suspension System part # ASR3500S06 which will retain the same torsion axle design and install in a very similar fashion which you can see in the attached install video. This will be the...

  • Parts Needed to Convert Trailer to Timbren Axle-Less Suspension System
    The Timbren Axle-less System, part # TASR5200S03, you've picked out works great with the wheel, part # AM20535, and brake assemblies, part # 23-458-459, that youv'e also selected. In addition to those you also need 12 inch hub and drum assemblies, part # AKHD-655-6-EZ-K, that fit the Timbrens. You also may want to get new hardware for the brakes using part # BRKH12. Other than that all you may need is a support beam to go across the trailer between the Timbrens. This depends if...

  • Recommended Axle Replacement For 5200 lb Dexter Axles With Electric Brakes
    The only axles we carry that are that 5200 lb capacity are the Timbren Axle-less Suspension System. For your application, I recommend the Timbren Axle-Less Trailer Suspension System - 4" Lift Spindle w/ Brake Flange - 5,200 lbs # TASR5200S03. This will replace your leaf springs and your axle. It has a brake flange and is compatible with standard hubs and drums. If there isn't a crossmember where you install your axle, you will need to use a 2 inch by 3 inch steel tubing to connect the...

  • 5,200 Lb Timbren Axle-Less System With Compatible Hub, Drum and Electric Brakes
    The Warner-style brake assemblies are no longer made and replacement parts are essentially non-existent at this point, so really your best option is going to be replacing your hub and drum as well as brake assemblies. You may also need to weld on a new brake mounting flange, which will be determined by the diameter of your axle. In order to find the correct replacement hubs for your trailer you need to know the weight rating of your axle, and also what bearings your current hub has....

  • Recommendation for Converting Fleetwood Neon Pop-Up to Axle-Less Suspension System with Jeep Tires
    To convert your offroad trailer to the Timbren Axle-Less Trailer Suspension System - 4" Lift Spindle w/ Brake Flange - 5,200 lbs # TASR5200S03 you will either use a crossbrace for your trailer frame at the axle location or you will add a 2 inch square tube between the assemblies (not included) into the integrated holes of the assemblies. This will give you much more ground clearance than a standard axle and will also include the suspension needed. Unfortunately that 5,200 lb Timbren...

  • Timbren Axle-Less Suspension System with Lift for Single 5200-lb Axle Trailer
    Timbren axle-less trailer suspension # TASR5200S03 is rated for 5200-lb applications, has 4-inch lift spindles and includes brake flanges. With this kit you can use 8-on-6-1/2 bolt pattern hub/drums that use inner bearing # 25580 and outer bearing # 15123 or # LM67048. You can use galvanized hub/drum # 8-219-50. For electric brakes you can use left- and right-hand kit # AKEBRK-7-SA which are self-adjusting and that work with 14-1/2, 15, 16, and 16-1/2-inch wheel diameters. Some...

  • What Tire and Wheel Size Fits Timbren Silent Ride Suspension TSR10KT02
    Timbren Silent Ride Suspension # TSR10KT02 is designed for 3 inch axles and those are usually rated for 6,000 to 7,200 pounds. So basically provided the tires are an appropriate size and capacity for the trailer you will be able to use them. On the low end (6,000 pound axle) that would be at least a 235/80-16 tire size. And on the higher end it would be a 235/85-16 or larger. I have included a link to all of the 16 inch tires, wheels, and tire and wheel combos we carry.

  • Raising Trailer with Welded On Torsion Axles
    There is a solution for you, but the lift kits you referred to such as # K71-725-02 will not work with welded on torsion axles. The best option is for you to simply remove your torsion axles and use the Timbren Axle-Less Trailer Suspension System # TASR5200S03, which is rated for 5,200 lbs and has a 4" lift spindle. With these you would need Hub and Drum Assembly # 8-201-5UC3-EZ or Idler Hub Assembly # 8-213-5UC1-EZ. With the Timbrens there is no alignment needed; the system does...

Instead, you will want to use the Timbren Axle-Less Trailer Suspension System part # ASR3500S06 with the Trailer Idler Hub Assembly part # AKIHUB-550-35-EZ-K as this will allow for the 4" lift with 5 on 5" bolt pattern.

  • Recommended 4 inch Lift Spindles or System to Raise Deck Height of Trailer
    For your specific application, we really only have one style of trailer axle and suspension that will work with your spring center to spring center dimensions.

  • Stainless Steel Disc Brake Kit Recommendation for Use with Timbren Axle Less Kit TASR5200S03
    The disc brake kit you mentioned does not include hubs so for use with the Timbren Axle Less kit part # TASR5200S03 that you mentioned running two of the part # K1HR526DS would be your best option. This kit includes a Dacromet-plated hub-and-rotor assembly, as well as a stainless steel caliper and Dacromet-plated mounting bracket.

  • Wheel/Tire, Hub and Drum, and Brake Assembly Recommendation for Timbren Axle Less Kit TASR5200S03
    For a brake drum to fit the Timbren kit part # TASR5200S03 that you referenced you would want the part # 8-201-5UC3-EZ. Then for a matching assemblies you would need # AKEBRK-7R-SA and # AKEBRK-7L-SA for either side. The part # AC225R6SMQ would be a great fitting wheel and tire combo that has a 2,540-lb max load at 65 psi for each wheel/tire.

  • Will Adding 4" - 5" Lift Axle Impact how a Trailer Tows
    Installing an axle that gives you more height on your trailer isn't necessarily a bad thing. The most important thing to remember is that too much height can cause your center of gravity to sit high enough that crosswinds and corners at higher speeds could cause adverse effects to your towing experience. With that being said, 4" - 5" of lift alone shouldn't be enough to make your trailer dangerous to tow. If you were to try lifting your trailer much more than that though is when you...

  • Recommended Ways To Lift 2008 StarCraft Centennial Trailer
    Since you have a torsion axle you can use spacer blocks to get more ground clearance. There are lift kits available if you have Dexter axles. Normally, people use 2 inch by 3 inch, or 2 inch by 4 inch steel tubing with 3/16 or 1/4 inch wall thickness. Raising the trailer will change the geometry of your trailer making it more top heavy and you may have more trailer sway. If you have leaf springs on your trailer you can add longer hangers. You would need to cut off the old ones and have...
