Recommended Clearance Between Trailer Frame and Axle

Question

Question:

I have a tandem trailer and have the axles over the springs, I have only 2 1/2inch clearance between the trailer frame and the top of axles. Is this enough clearance so when the trailer is loaded the axle and frame will not hit each other?

The recommended clearance with leaf spring suspension on an unloaded trailer is between 2 - 2-1/2 inches. You should have sufficient clearance with your loaded trailer, as leaf springs only tend to deflect 1-1/2 inch when carrying a load.

Channel Tongue Trailer Coupler #CT-3001-Z requires a 2 inch wide tongue but I recommend a boxed tongue and not C-channel so there is more support where it counts. Steel tubing at least 1/8 of an inch of wall thickness will do the trick. The length…

Correct, you will need to have a spring set installed on the axle tube to hold the leaf springs in place and prevent them from sliding back and forth. That said, although we do not have any spring seats specifically for a square tube axle you can use…
