How to Pick Leaf Springs for a Trailer

Updated 05/07/2014 | Published 05/06/2014

Question:

I have a broken leaf spring on a 10 ft big dog manufacturing trailer made in 1995. I know it is a 4 leaf double eye but do not know the axel size. I am in Vegas and the trailer is in Utah. How do I order the correct leaf springs. Thankyou for your help.

If you look on the frame of your trailer there should be a plate with the trailer VIN number and the axle capacities of the trailer. You will want to pick leaf springs that are as close to the axle capacity as possible.

You will want to also measure the distance from eye to eye of your old leaf springs and then pick a leaf spring with the same weight capacity of your trailer axles and that is slightly shorter (around 1 inch) to compensate for the sag and wear of the old leaf spring.

Leaf springs should be replaced in pairs to help keep your trailer stable while being towed.

I have attached an FAQ articles that reviews trailer suspension components for you below to check out.
