Determining Replacement Leaf Springs For a 5TH Wheel Camper Trailer With 12,000LB GVWR

Question:

I have a fifthwheel trailer with a 12000 gvwr, my questions are 1. What leaf springs do I need and 2. Is there any difference in a length of 251/8 and 251/4.

I have linked an article below which will help you to accurately measure your leaf springs to ensure you get the correct length. With your 5th wheel trailer having a 12,000lb GVWR you will most likely have 6,000lb double eye leaf springs like # e34SR. While you can use either this Spring # e34SR which is 25-1/4" and the Spring # e47SR which is 25-1/8" on the same trailer as they are so close in size the particular difference in these springs is the amount of leaves they use. Having more leaves on the springs allows for the spring to flex more easily which typically gives a better ride quality for the trailer.
