Could Timbren Axle Less Kit Be Installed on Truck Bed Trailer Frame

Question

Question:

Have a homemade pickup bed trailer, 1/2ton leaf springs. Trailer has a 7k 3inch round mobile home axle. The springs are rather soft and cause major body roll if the trailer isnt loaded down to the bump stops. Currently have a pickup-bed camper loaded on it, which is not heavy enough to sit the trailer on the bump stops. And body roll is at a dangerous tip over point. Part # TSR7KS02 seems like an excellent replacement to the soft springs...only question is are these able to be fitted on a Vehicle frame persay? or will they require further frame fabrication? Part# TSS-107-40 also seems like another alternative option, although im unsure how stiff they are, as in will they stop/prevent body roll before they are compressed 50 or more.

Helpful Expert Reply:

The Timbren Silent Ride # TSR7KS02 that you referenced was intended for attaching to a trailer frame, but could also attach to a truck frame too assuming it's a standard boxed frame. I attached a picture that shows how it typically bolts to a frame and shows relevant dimensions that you should check out and compare.

You really don't want to install suspension enhancement like the # TSS-107-40 you referenced on suspension that is showing signs or being worn out like yours. These kits should only be used on trailer suspension setups that are in good working order.

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…

I have attached for you below some common torque values needed for a trailer suspension system but a lot of these will vary by bolt size and other factors. U-Bolts: Varies by Size - 1/2" bolts: 45 ft/lbs - 70 ft/lbs, 9/16" bolts: 65 ft/lbs…

Answer 6

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 the…

Answer 7

The spring hanger placement is going to be determined by your axle spacing. For example, if your axles are spaced 33 inches apart, as shown in the attached diagram, a 7K axle slipper spring, like #e74SR, requires a distance of 28-1/2 inches between…

Since Grand Design is kind enough to list certain parts for their trailers I can confirm you have a 33" wheelbase on your 2020 Grand Design Transcend 27BHS. This means the MORryde Rubber Equalizers #MR87ZR will fit your trailer. Although I'm…

Answer 9

The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13 like…

Answer 10

A BT8 spindle would have a diameter of .99 of an inch where the bearings would both install and would have a diameter of 1.24 where the great seal would ride. That would require a hub part #AKIHUB-440-2-1K for an idler hub. A BTR spindle would have…

Answer 11

To determine the size of the hub assembly you need to purchase you have to determine which bearings are in the old assembly. If the old assembly has L44649 inner bearings, you would use the hub you chose #8-258-5UC1. If the inner bearings are marked…

Answer 12

Assuming your tires are in good shape without any bulges the easiest way to determine if you have a bent spindle is to take a straight edge that is longer than the tire and lay it across the tire parallel with your trailer frame and then measure the…
