Replacing 24-1/4" Slipper Springs On A 4x6 Carry On Trailer

Updated 01/12/2026 | Published 09/03/2024

Question:

I have a 4x6 Carry-on trailer that i bought from Tractor Supply years ago. my slipper springs measure 24-1/4 from center eye to end, which is in spec with Carry -On direct replacement . Im looking for a softer ride because i never have anywhere close to that on the trailer. Will your 24-5/8 inch slipper spring work in this application , its slightly longer but rated well below what my 200 axle is rated for ? I assume its fine but wanted to ask before i order. My spring hangers measure like 22-1/2inch from the front hole center to the front face of the slipper bracket

Hello JT, thanks for reaching out. Yes, the 24-5/8" long 3-Leaf Slipper Spring # e99SR will indeed work to replace your 24-1/4" long springs. When replacing leaf springs there is a small amount of tolerance, and a 3/8" difference is not going to throw off your suspension or anything. Just keep in mind these springs are for a 1,500 lb axle and each spring is rated for 750 lbs so please just be aware of this and make sure your don't overload the springs.

Hey JT, how did the swap to the 24-5/8 inch slipper springs work out on your Carry-On trailer? Did they give you the softer ride you were hoping for? Your feedback could really help others trying to fine-tune their trailer suspension.
