My boat is finally riding right! Easy install, a bit shorter than I needed but just added a couple of brackets and bam!

A really great set of leaf springs, at a fair price and FAST shipping! I recommend NEVER using USPS when possible as they SUCK! Use FED-EX or UPS every chance you can!

Checked locally for springs and the shops wanted at least twice as much. Springs were as advertised and are working great on my pontoon boat trailer. If the salt water eats these I will purchase another set to replace them.

I returned these.. I needed them for a truck, and these was for a trailer..

Just doing some maintenance to my boat and trailer during all this covid-19 shutdown. They took about 30 to 45 minutes to put on. worked great

Had to replace our two springs on our pop up trailer. Fit perfectly. On driving to Yellowstone, the springs were so smooth we forgot we were towing the trailer!

Exactly what I needed. Installation was easy and matched up perfectly. Product came in quicker than expected. No negatives here.
