How to Pick Out the Correct Replacement Leaf Springs for a Tagless Axle

Updated 08/06/2024 | Published 08/04/2024

Question:

I have a single axle utility trailer that was converted to hold a smoker pit that is pretty heavy. I feel the springs have flattened out a bit and could be upgraded slightly. I assume the axle is a 3500 lb axle but I do not know how to determine this for certain. There are no markings. I took all weight off one side and measured the leaf springs. They are 4 leaf double eye with eyes 25.5” apart. How do I know which I should order?

It probably is a 3,500 lb axle, but you can verify this by measuring the axle tube diameter. For instance, a 3,500 lb axle will measure 2 3/8" in diameter, and would make the 4-Leaf Double-Eye Spring for 3,500-lb Trailer Axles # DX23CR the best replacement.
