I have an old truck bed trailer with a broken axle and am interested in upgrading it to an axle-less trailer with breaks. What should be the parts list needed to upgrade my trailer? Or is it even doable? Thanks

The Timbren Axle-Less Trailer Suspension System - 4" Lift Spindle w/ Brake Flange - 5,200 lbs # TASR5200S03 will work well for your old truck bed trailer. The Axle-less system will allow you to have a custom fit to your trailer frame. You will simply bolt the assemblies to the frame and then run a 2 inch square bar (not included) through the integrated holes in the assembly.

Then add the brakes and hubs and compatible wheels and you'll be good to go. The wheels in your current photo won't work because there are not hubs with that bolt pattern that fit this axle. For hubs that match this axle, you will want the Dexter Trailer Hub and Drum Assembly - 5,200-lb E-Z Lube Axles - 12" - 6 on 5-1/2 # 8-201-5UC3-EZ. Then I recommend the Electric Trailer Brake Kit - Self-Adjusting - 12" - Left and Right Hand Assemblies # AKEBRK-7-SA and hardware # BRKH12.

If you don't want trailer brakes, you can use the idler hubs # 8-213-5UC1-EZ instead.

Finally for tires and wheels, I recommend the Provider ST235/80R16 Radial Trailer Tire w/ 16" Silver Mod Wheel # TA59VR. These combinations will fit the hubs and are rated for 3,520 lbs at 80 psi as well as speeds up to 81 mph. They come with a 2 year Platinum Plus warranty that includes roadside assistance as well.

Let me know if you have further questions.

It won't cause the slightest bit of a problem. As long as the bearing numbers, wheel bolt pattern and grease seal dimensions match up, the #84545UC1-EZ would be an appropriate replacement. Several years ago, this hub model was…

Well shackle length is mainly based on the height difference between the front and rear hangers. The rear hanger normally doesn't hang as low as the front so that the shackle can offset the difference and add the ability to move. What is…

I definitely recommend replacing your 3,500 lb 26 inch leaf springs with the 26 inch 4-Leaf Double-Eye Spring for 4,000-lb Trailer Axles #e22YR. The 4,500 lb would be too stiff and your ride would suffer so the better option by far are the 4k…

When replacing the leaf springs on your 6 x 12 utility trailer you will need to match all of the dimensions and the spring capacity as closely as possible to the original spring. Usually the measurement from eye to eye will lengthen and the height…

The easiest way to determine the correct replacement parts for your trailer's suspension is by simply measuring its existing components. Looking at one of your current equalizers, you will want to measure from the center of the front hole to the…

Thank you for providing the specs for the suspension components that you already have. Correct hanger spacing really depends on the components being used such as springs, hangers and equalizers. Most of the hanger spacing dimensions that we have are…

The over-under conversion kit, #K71-384-00, is a bolt on kit, welding is not required for installation but the manufacturer instructions state that tacking the spring seat is strongly recommended. This kit is designed for 2-3/8 inch diameter axles.…

Answer 8

The first thing I would check on your trailer is the capacity of the springs. You need to be sure the spring capacity is rated at 1/2 the axle capacity. That way 2 springs equal the capacity of the trailer axle for proper fit. Check the arch of the…

There is not a specific torque spec for shackle bolts including the ones in the Tandem-Axle Trailer Hanger Kit part #APT3. They need to be secure but if they are too tight then the leaf springs will bind and cause problems in your trailer's…

Answer 10

I believe what you are saying is that your axle is mounted with the leaf springs underneath the axle, which is why your tie plate is mounted on the bottom. We have previously confirmed with Lippert that the Bolt-On Shock Kit #LC281281 cannot be…

Answer 11

You will want to remove your spring hangers and then weld them in a position that allows the shackles to hang properly. On a spring that is 26 inches eye to eye on center and a single axle trailer you will want the hangers to be up to 1/2 inch less…

Answer 12

Trailer manufacturers don't usually keep a record of parts like these that they install at the factory, so I cannot be sure as to the exact length of the shackle strap that would have come originally on your trailer. With this in mind, a 3-1/8…
