Question:

Im looking for a spring kit with hardware to replace my leaf springs on a single axle 3500 lbs trailer. The eye to eye measurement is 25 1/4. There are 4 leaves measuring 1 3/4 wide. And there is a bracket ping down from the back hanger that measures 4 1/4 long. Do you have a kit like this?

Hey Mike, thanks for reaching out. Yes, we have just the thing. The 25-1/4" long 3,500 lb leaf springs are basically standard, so we can definitely provide those along with a bolt/shackle kit for your single axle trailer. Here is what I recommend:

- 4-Leaf Double-Eye Spring for 3,500-lb Trailer Axles - 25-1/4" Long - EMCO # EM88UJ

- Dexter Heavy Duty Suspension Upgrade Kit for Single Axle Trailers -3-1/8" Shackle Straps # K71-358-00

- U-Bolt Kit for Mounting 3,500-lb, Round Trailer Axles - 5-1/2" Long U-Bolts # APUBR-1

That will cover everything you need. The suspension kit comes with HD shackles, wet bolts and bronze bushings which will be a nice upgrade over the stock suspension. Hangers are not included with this kit, so you will just be reusing the old ones. Also, since you are replacing the leaf springs, new U-bolts will be required.

What kind of trailer are you servicing?
