Timbren Trailer Axles - ASR2000S01

Highlights

2,000 lb Capacity: Supports small to mid-size trailers while keeping towing stable and smooth.
Axle-Less Design: Removes the axle beam for more ground clearance and frame flexibility.
Rubber Jounce & Rebound Springs: Absorb shock and reduce bounce for a quieter, steadier ride.
Independent Suspension Arms: Each side moves on its own, improving cornering and handling.
E-Z Lube Spindles (L44649 Bearings): Simple greasing and easy hub maintenance.
Standard-Height Spindles: Keep trailer deck height unchanged while improving clearance.

Features to know about

Smooth Ride on Rough Roads: AEON Rubber Jounce and Rebound Springs Absorb Shock

Bumps and potholes don’t have to mean a harsh ride. The Timbren Axle-Less Trailer Suspension uses AEON heavy-duty rubber jounce springs to soak up road shock and support the load, while rebound springs keep the trailer steady by minimizing roll, bounce, and bottoming out. The setup stays quiet and smooth whether you’re hauling gear or running light, keeping the trailer stable mile after mile.

More Clearance Without Raising the Deck: Axle-Less Design Keeps Standard Height

Traditional axles hang below the frame and eat up ground clearance. This Axle-Less design eliminates the beam axle so nothing hangs low, giving you more room under the trailer to clear dips and uneven ground. The standard-height E-Z Lube spindles keep your deck height the same, so loading stays easy while the frame gains extra clearance for plumbing and other underbody parts.

Independent Suspension for Better Handling: Each Side Works on Its Own

When one wheel hits a bump, the other side shouldn’t feel it. Each of the two suspension units works independently, improving handling and reducing stress on the frame. Built-in camber and toe-in help protect tires from uneven wear, so they track straight and last longer. The result is a stable, balanced trailer that doesn’t sway or twist through corners or rough spots.

Built Strong for Everyday Use: Steel Construction with E-Z Maintenance

Each suspension arm bolts directly to the trailer frame for a secure mount. The steel construction is finished with a black powder coat that resists rust and corrosion. The integrated E-Z Lube spindles make bearing maintenance simple with built-in grease zerks, and if a spindle ever gets damaged, it can be replaced without welding or buying a whole new axle.

Flexible Fit for Custom Builds: Fits Any Frame Width and 2,000 lb Capacity

This system replaces one standard axle and all related suspension parts, fitting any trailer frame width. It’s rated for a 2,000 lb total capacity and uses compatible hubs with inner and outer bearing L44649. Each unit offers 2-7/16" of suspension travel and accepts 14" or smaller wheels with ST195/75R14 or smaller tires. Whether you’re upgrading worn leaf springs or building from scratch, it’s a versatile setup that’s easy to configure and built to last.

Note

This Axle-Less system requires crossbeam support.

You could also add a steel reinforcement bracket to the inside of the trailer frame.

I used this on my sailboat trailer to lower the height on the boat. A traditional drop axle would interfere with the fin keel. I used the box tube to connect the two units together for added strength and protection. The tube is well ahead of the keel and where the drop axle would have been. I'm also thrilled to have the Timbren elastomer shocks which give a super smooth ride and are immune to corrosion of the salt environment. Multi-leaf springs just don't last when immersed in the ocean, no matter how hard you try to flush them.

Best axle system for overland trailers and their travels, great independence system for those 1-6 trail ratings, simple to work on , easy bolt on system. I would recommend to grease after each trip . The standard Duty -4" Drop- 4Bolt Flange- 3500 lbs give me about 21" clearance with 35" x 12.5 tires

Hey Alan. I love seeing all your progress pics. However, I think my favorite part is the camper art on the back! Do you have a bucket list location you want to take it to?

by: dale 04/21/2021 One Year Later

The trailer rides great down the road and no more worries about saltwater and rusty leaf springs. Not a cheap option but I’m very happy with the setup. When installing, just be sure to measure accurately and have sharp drill bits. A drill press type of guide also helps ensure correct drilling angles. The first picture is of a mounting gusset a local welding shop made. One is needed for each side and necessary to provide needed mounting strength-at least on my trailer frame. Pics 2 and 3 show the mounted suspension on one side of the trailer. Pic 4 shows the suspension on one side of the trailer with the axle attached and a separately purchased disc brake assembly mounted on it. Finally, pic 5 shows a 2” box channel between both suspension assemblies. Independent suspensions would have been nice, but I wanted to ensure trailer rigidity was maintained. So, after one year, so far, so good. It’s all smooth sailing down the highway.

Actually over a year, and still working great.

by: Jake 08/21/2023 One Year Later

Installed the Timbren Axle-less suspension a little over a year ago and approximately 5000 miles ago. I have been extremely satisfied with the installation and performance thus far and have had no issues. I also chose to install an optional crossmember for more strength using a 1/4" thick piece of 2x3 steel. I had to increase the weight capacity of my campers suspension due to renovating the interior completely and adding more weight. I also strengthened the frame to accommodate the extra weight. In addition to installing the Timbren 5200LB system I installed new 12" electric brakes and upgraded to 225/75R15 tires with E load range rating.

by: Scott 02/12/2021

Very exicited about these axels, I have been eyeing these for over a year. (Excellent service from etrailer, they had my parts to me in 1 day from the time of placing the order.) These axles seem to be well made and fit nicely with the Dexter hub and drum assembly and the 12" electric brake kit. I installed this all on a M1101/M1102 trailer frame after removing the factory axel assembly. I have not ran these on the road or off as of yet but will give another review at that time. The fit and finish are great and the packaging was good, a little banged up from shipping (missing 1 washer)

Timbren saved our RV road trip! The leafs on the axle on our 2018 Jayco TT came apart while driving in Maryland. We tried going to the manufacturer, but they were useless. Going to a RV mechanic meant being grounded for at least 2 months. Then we found Timbren. With the help of Timbren's excellent staff we purchased axle-less system through etrailer, who made sure we got as quick as possible. It came ahead of schedule, my husband installed the Timbren system and we were back on the road! The axle-less system is better than the original manufacturers. If you plan on taking your RV or TT farther than 100 miles GET THIS INSTALLED and get it through etrailer.

The order came in on time and the customer service at etrailer.com (Ashley) and Sean from Tmbren was outstanding. They both were very helpful in my choosing the right product for my needs. The axle less suspension's performance is absolutely superb. It vastly improves ride quality. I am using it on a teardrop camper that often goes on gravel roads and the raddling sound from the leaf axles was horrible. A couple of points to consider before you settle on the axle less suspension: keep in mind that you will lose some hight of the trailer. While you will gain clearance from the lack of the axle, the suspension will make the trailer sit lower than before.i had to lower my hitch by an inch to maintain the trailer leveled. Also it does appear to compress at higher rate than the leaf springs, which makes it softer but easier to reach it's limit. Overall this product is absolutely a must if you are looking to improve the safety and the quality of your towing.

Hi Amy,,
I got my order yesterday, it is perfect for what for my off road camper trailer project.
Maybe a little (lot!) Over kill, but where it will be going I don't think over kill is a bad thing.

I have made a lot of purchases from you guys and have never been disappointed.

I will probably need to purchase the hub/break assembly next.
Thanks for everything,

Actual trailer weight 1540#, 210# tongue weight. 1310# suspension load. After 600 miles, both springs collapsed making the suspension rigid. Have received replacement springs from Timbren but haven't had a chance to try them out.

Can Brakes be Used with 2k Timbren Axle Less Kit
Hey Devin, there is a way to use the Timbren Axle Less kit you mentioned and have brakes but you would want the kit part # ASR2000S01 that doesn't come with hubs so that you could use the hub/drum part # AKHD-545-2-EZ-2K and the brake assemblies you referenced AKEBRK-2.

Recommended Higher Speed Rated Tires For Harbor Freight Trailer W/ 4.80-12 Tires
Typically on a trailer the only part that has a speed rating is the tire itself, though you will need to contact the manufacturer of the trailer to confirm this. Based on the tag shown in your picture your trailer uses a 4.80-12 so for a high speed replacement we have the Taskmaster 4.80R12 Radial Trailer Tire - Load Range C # TT48012C which will be an exact replacement, but has an 81 MPH speed rating. Should you find that the hub has a speed rating, just let me know the bearing combination...

How to Find Replacement Axle for Hammerblow Trailer
Hi Ryan; to find a replacement axle you need to know the capacity as well as the hub face to hub face measurement (which is considered the length). It is also helpful to know the spring seat measurement but the spring seats on a replacement can be cut off and moved if need be. I would check to see if there is an axle tag with the capacity if you aren't 100% sure. I also attached a video below which shows how to measure. Assuming you have a 2k axle we have the following lengths available: -Trailer...

Replacement Axle for a 77" Hub Face
Hey Ron! We do not have an axle that comes even close to matching your dimensions. The only solution I have to offer you is one of our axle-less systems like the Timbren item # ASR2000S01. This is an independent system that has no axle beam. They come in many capacities and set ups like idler hubs or electric brakes. If you would like a more specific recommendation, I would just need to know your axle capacity, lug pattern, and whether or not your trailer has brakes. You can comment this...

Replacement Option for 2005 Yacht Club Boat Trailer Axle
Hey Curtis! I do have a solution, but I can tell you based on that design we do not have a standard replacement.

This would be 1/4" shorter on each side and has a 2,000 lb capacity. You would also have to cut off the spring seats and weld on # TRSS175 to match your 60" measurement.

Timbren Axle-Less System vs. Torsion Axles for a Sail Boat Trailer
I recommend the Timbren Axle-Less Suspension System # ASR2000S01 over a torsion axle for your trailer for a few reasons.

They also operate independently of one another to minimize bounce for a smoother ride compared to the torsion axle system. An E-Z lube spindle is included with the system, but a Trailer Hub...

Replacement Axle Recommendation for Yachtclub Snowmobile Trailer Rated for 1,880 Pounds
For your snowmobile trailer I recommend going with a Timbren Axle-Less system such as # ASR2000S01. I have included a link to all the options rated for 2,000 pounds. The benefit is that you won't have an axle beam to rust and you still get the rubber, torsion-style suspension. To determine if the hubs you have now will fit I just need to know the inner and outer bearing numbers stamped into the sides of the bearings.

Can Timbren Axle Less Suspension System Install on C-Channel Trailer Frame
We've had this question sent into us before and when we spoke with Timbren they told us that the C-channel frame design will be fine assuming that he open part of the C is on the inboard side and not the outboard side of the frame. If the C opening is on the outboard side you would need to box out the frame by having a professional welder weld the C-closed. Since your C-opens to the inside of the trailer frame you do not need to do this to install the # ASR2000S01.
