Expert Answers about Timbren

  • Best Way to Prevent Sagging Suspension When Towing a Trailer
  • For sag from towing a trailer the best recommendation I can make is actually a weight distribution system. Suspension enhancement will help level your truck while towing. But the advantage to a weight distribution system is that it levels the vehicle by distributing the tongue weight of the trailer up to the front axle of the vehicle as well. This will help greatly with handling and braking, especially in an emergency situation. The best way to pick out a weight distribution system is...

  • Rear Suspension Enhancement Options for a 2004 Cadillac Escalade EXT
  • I may have a solution that will work for you, however, we do not offer replacement air shocks for your 2004 Cadillac Escalade EXT at this time. We do offer coil spring air bag inserts like the AirLift 1000 Air Helper Springs, # AL60769. These air bags fit in the rear coil springs and can be manually inflated for additional support. Another option would be a bump stop replacement like the Timbren Rear Suspension Enhancement System, # TGMRG25C, that you referenced. These are rubber springs...

  • Comparing The Timbren Axle-Less Trailer Suspension System To The FlexiRide Half Torsion Axle System
  • For an off road overland trailer, I recommend you go with the Timbren Axle-Less Trailer Suspension System with Hubs - 5 on 4-1/2 - Off-Road Tires - 1,200 lbs # A12WS545 and not just because we carry them...as I know seems like a conflict of interest. The Flexiride system even with a 1,400 lb capacity is not made for off road and the suspension is a torsion system with rubber cartridge on each side. The Timbren system uses more of a jounce style bumper that the company is known for regarding...

  • Replacement Axle Recommendation For Small Popup Camper
  • The axles we offer are available in 3 lengths. They are 60 inch, 72 inch, and 89 inches hub-face to hub-face, but I may have a solution for you. We do offer axle-less systems that are either bolted or welded to the trailer frame. This would replace the axle and suspension system you currently have on your camper. If you are looking for a system that has a 3,500 lb weight capacity, I recommend part # A35RS545. This is a straight spindle and has a 5 on 4-1/2 bolt pattern. For a system...

  • What would I Need to Upgrade from 3,500 lbs Tandem Axles to 5,000 lbs Tandem Axles
  • We carry the Timbren Axle-Less System rated at 5,200 lbs part # ASR5200S01. The axle-less system mounts to your trailer frame and takes the place of your old axle and springs.# ASR5200S01 is a straight spindle design. Timbren also offers these axles with a 4 inch drop spindle part # ASR5200S04. The Timbren Axle-Less can be mount tandem to repalce your tandem axles. There is no need to install leaf springs, because the Timbren axles have built-in spring system on each axle. However,...

  • Recommended Trailer Axle Kit for Fabricating Off-Road Utility Trailer
  • If you are building your own firewood hauling trailer you might want to consider one of our Timbren axle-less suspension kits. These are available with idler hubs and some also have lifted spindles that can give you better ground clearance (for use in the woods when gathering your firewood). We do have standard beam axle kits too but the Timbrens can be the ideal way to go for fabricators that want an effective but simple installation of their trailer suspension. The linked page will...

  • Rear Axle Suspension Kit Recommendation for 2013 Ram 1500 Quad Cab with Coil Springs
  • The Timbren rear axle jounce spring kit you referenced, part # TDR1500DQ, is a fit for your 2013 Ram 1500 Quad Cab. This rear axle kit fits both 2WD and 4WD models. There are several types of rear axle kits available for your Ram 1500. These include rubber jounce springs like the Timbrens, air bag kits from AirLift and Firestone, and coil springs such as the SuperSprings Sumo urethane coil helper springs. The link provided will take you to our page showing all of these products. The...

  • Timbren Axle-Less Trailer Suspension System Recommendation for a 1977 13 ft Scamp Trailer
  • Converting a torsion axle trailer to a trailer with a Timbren Axle-Less Trailer Suspension System has been done before and most people who have done this really prefer the smoother ride and increased ground clearance. Timbren 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...

  • Adding Trailer Brakes to a Timbren Axle-Less Trailer Suspension System
  • Yes, it is possible to add brakes Timren Axel-Less Trailer Suspension System. The Timbren Axle-Less Trailer Suspension System - 4" Lift Spindle w/Flange - Off-Road Tires - 2.2K, # ASR1THDS03, that you were looking at has the brake flange mounted, so it is ready to add brake assembly and hubs to. I'd recommend getting the Electric Trailer Brake Kit - Self-Adjusting - 10" - Left and Right Hand Assemblies - 3,500 lbs # AKEBRK-35-SA . You would then pair these with the Trailer Hub...

  • Reducing Rear End Squat when Towing Trailer with 2014 Ram 1500 Crew Cab 2x4
  • Normally weight distribution is the best option when squat is caused by a coupled trailer. But since the manufacturer of the trailer specifically said not to use it the next best option would be suspension enhancement for your 2014 Ram 1500. I do recommend the Timbren springs # TDR1500DQ because they do work well. They may allow the suspension to travel some before they engage but the squat should be reduced if not eliminated. I have included a link to a video showing installation of...

  • Can Timbren Axle-Less Suspension System Work With Off-Road Tires?
  • There is a 2,000 lb capacity Timbren Axle-Less Suspension with 4" Drop Spindle # ASR2KHDS09, though not a 1,200 lb one. I am not certain what you are referring to in terms of "strong enough" but it will work with 3,500 lb rated hub and drum assemblies # 84546UC3-EZ as well as 3,500 lb brakes. If you were referring to your trailer being strong enough, if you do not have a crossmember above where you want to install the Timbren one will need to be added, or you can reinforce your trailer's...

  • Suspension Enhancement Recommendation for a 2011 Dodge Ram 1500 Towing a Gooseneck Trailer
  • For occasional towing with your 2011 Dodge Ram 1500, I would go with the Timbren suspension enhancement system. If you do not have a Quad Cab, use # TDR1500DS. If you do have a Quad Cab, use # TDR1500DQ (instructions linked for reference). The Firestone systems are good when you carrying varying sized loads and have to adjust the ride accordingly. But for occasional towing of the same trailer, the Timbren system would be the way to go.

  • Hub Recommendation for Timbren Axle-Less System ASR1THDS03 with Jeep Bolt Pattern
  • Typically the Jeep wheel bolt pattern is 5 on 5 inch. For an idler hub that will fit the spindles of the part # ASR1THDS03 and have the correct bolt pattern we have the # AKIHUB-550-35-K. This is a 3,500 lb trailer hub. The # ASR1THDS03 has a 4 inch lift built into it so it would work well for you since your Jeep is also lifted.

  • Tips for Reducing Sway When Towing Ice Castle Fish House RV Trailer
  • I looked up pictures of the coupler setup of your trailer and it would not be compatible with a weight distribution system since it basically uses a pole tongue and has a pipe that runs on top of the pole tongue as well. What you can do to fight sway is make sure that you have the trailer setting as level as possible when you are towing. (See help article on how to pick out the correct ball mount to allow this). Most sway is due to not having enough tongue weight relative to the...

  • How to Decrease Sag on 2016 Ram 1500 When Towing
  • A Timbren Rear Suspension Enhancement System is a great way to reduce sag on your 2016 Ram 1500. They're easy to install without any drilling by replacing the factory bump stop. If your Ram is a Regular Cab, you will need # TDR1500DS. If you have the Crew or Quad cab, then you'll need # TDR1500DQ. I've included an installation video on a 2014 Ram which is a very similar process to yours. The best way to reduce sag is with a weight distribution system. A weight distribution system...

  • Is the Timbren Axle-Less Trailer Suspension System a Good Choice for a Motorcycle Trailer
  • The Timbren suspension system, like # A20RS440, is designed to be toe-in when there is no load on it. So when the load is placed on it it will push the tire out so that it is riding straight on the ground. Provided the trailer is not overloaded and the tires are trailer tires and inflated to the maximum psi as indicated on the tire, then you should not see excessive wear and get more than just a few thousand miles out of a set. A regular axle has a bow in it. That bow should be pointed...

  • Suspension Enhancement or Weight Distribution for 2012 Dodge Grand Caravan Towing 21 ft Camper
  • The Timbren Rear Suspension Enhancement System you mention is primarily meant to suspend weight carried in the cargo area of the vehicle itself, but it would not necessarily be the best choice to act against the sag caused when the trailer is hitched to the vehicle. While the tongue weight does compress the rear suspension of the vehicle, it also unloads the front suspension which will reduce braking and steering performance. As you can see from the video I have linked you to, the Timbren...

  • Parts Needed to Add Timbren Suspension and Electric Drum Brakes to Tear Drop Trailer Build Project
  • Timbren offers their axle-less trailer suspension systems in many configurations, some with brakes and drums, others with idler hubs for applications without brakes. All of their kits are shown on the linked page. A trailer can require brakes based on its gross weight, GVWR. You want to choose the Timbren kit that matches the trailer's intended GVWR. You do not want to pick a system that is rated for more weight than your trailer will have as this will tend to produce a rougher ride....

  • Replacing 3500-lb Axles with 5200-lb Axles on Enclosed Cargo Trailer
  • You can change out the 3500-lb axles on your enclosed trailer with higher-capacity 5200-lb axles but this will not necessarily increase the weight capacity of the trailer. The trailer manufacturer should be consulted (giving them your trailer's VIN) to allow them to determine if the other components in it, such as its frame, have the capacity to allow you to benefit from increasing the axle rating. Also, it will likely be necessary to change your hubs to ones that are higher rated to...

  • Removing Factory Suspension Bump Stops on 2011 Chevy Silverado to Install Timbren Rubber Springs
  • The bump stops are compression fit into the cups on the truck frame, therefore they aren't designed to come out easily. I have spoken with one of my contacts at Timbren, who tells me that the bump stop can be removed with a pair of channel lock-type pliers. Grasp the bump stop with the pliers and pull down on it while twisting back and forth. In case you do not have them handy, I have provided a link to the install instructions.

I recommend using the Lionshead Trailer Wheel Lug Nut - 1/2"-20 - Stainless Steel - Qty 1 # LHLR103 and wheel locks # RG01-150. I also recommend the Trailer Wheel Center Cap, Stainless Steel, 3.19" Pilot Size # 319EZ-SS for a finished look. You can use the rubber valve...

  • Components Needed To Build A Utility Trailer
  • Building a trailer can be pretty involved. You need to consider the materials you want to use and the weight capacity of the trailer when you build it. You said you have access to a welding shop. You will need to design the trailer frame and decide what kind of tongue you plan on using. We do have several of the components you can use. For a suspension system I recommend using an axle-less idler hub system like part # A20RS545. This system has a 2,000 lb weight capacity and includes...

  • 2015 Ford F-150 Sags at the Back When Coupled to Trailer with 550 Pounds Tongue Weight
  • Sag at the rear of a vehicle such as your 2015 Ford F-150 can happen from 1 of 2 ways. First, weight in the actual truck bed can cause sag. Second, the tongue weight from a coupled trailer can cause sag. The ways to deal with the sag are different. When sag is caused by a trailer the recommended solution is weight distribution, not helper springs. Weight distribution will more evenly distribution the force of the tongue weight to all of the axles on the tow vehicle and trailer so it...

  • Timbren Axle-less Trailer Suspension Kit That Includes Spindles and Hubs
  • I recommend using one of the Timbren axle-less suspension kits to build your ice house trailer. These kits are shown on the linked page and are available with or without idler hubs. Both 4-on-4 and 5-on-4-1/2 wheel bolt patterns are offered. Kit # A20RS545 is rated for 2000-lbs, includes 5-on-4-1/2 idler hubs and spindles and can bolt or weld on. Please refer to the linked video for more information on this kit. I also linked 15-inch wheel/tire items that will fit these hubs.

  • Height of Timbren Helper Springs for a 2017 Ford F-250
  • There are actually just 2 Timbren helper spring kits for the 2017 Ford F-250. First we have # TFR250SDJ which has an 8,600 pound capacity and fits 2- and 4-wheel drive models. And second we have # TFRTT350J which is rated for 8,000 pounds and also fits 2- and 4-wheel drive models. So each of those part numbers appears twice because of the 2-wheel drive and 4-wheel drive categories. The springs in kit # TFR250SDJ are 4-1/2 inches tall and for kit # TFRTT350J they are 3-9/16 inches tall....

  • What Brake System is Recommended to use With Timbren Axle-Less Suspension?
  • If you plan on using the Timbren Axle-Less Trailer Suspension System # ASR2000S02, I recommend using electric brakes with your teardrop trailer. To add these, you would first need the hub and drum assembly that is compatible with the Timbren, # AKHD-545-35-EZ-K. For electric brakes, I recommend the Electric Trailer Brake Assembly - Left Hand # AKEBRK-35L-SA and Electric Trailer Brake Assembly - Right Hand # AKEBRK-35R-SA. You would need an electric brake controller for these brakes,...

  • Will a Kenda 215/60-8 Bias Trailer Tire and Wheel Fit the Timbren Axle-Less System part # A12WS545
  • Yes, the Kenda 215/60-8 Bias Trailer Tire with 8" White Wheel # AM3H310 is going to fit on the Timbren Axle-Less System part # A12WS545. If you check out the picture I attached you will see that when the Timbren is installed you will have a distance of 6-7/8 inches from the hub face to the trailer frame and the backspacing of the # AM3H310 is 4 inches so there would be more than enough clearance.

The contents of the kit are designed for the stop over the axle as seen in the attached diagram. This kit includes 2 aeon rubber springs. The # TDR5500 can be installed whether you vehicle was equipped with or without factory top overload springs. What it sounds like you are describing is the upper overload springs.

  • Methods of Improving Sway Control on 31 Foot Rockwood Camper towed Behind Ford F-150
  • The Timbren Rear Suspension Enhancement System you mentioned, # TFR1502D is primarily designed to suspend the load of cargo stored in the bed of your truck, and will not have much if any effect on trailer sway. First and foremost, if the trailer has insufficient tongue weight, it will be more susceptible to sway. The tongue weight of the trailer should be at least 10 percent of the weight of the trailer. If it is less, try moving some of the gear stowed in the trailer forward of the...
