Quality product was not expecting the leaf springs and hangers to be so well made for the price.

Kit provided all fasteners and parts needed to replace a very old system. Was impressed with how easy it was to install. Loose assemble ALL parts before tightening to aid in aligning. You will save :10 off the :65 it took me to finish the installation.

Broke a main spring in my First Out Work Trailer, ordered this kit, came quickly, replaced both sides in under a hour and back to work. It honestly worked perfectly. There was a extra leaf then my other spring pack had, but a little heavier duty never hurt anything

Edit: hopefully this bad review hits Libra the seller and not Amazon, when I attempted to contact both Covercraft (the company the product support links directed me to) and Libra regarding this issue Covercraft wanted nothing to do with it and Libra never contacted me back. When I contacted Amazon however they issued full refund without return of the kit. 5 stars Amazon. Zero stars Libra. Now I have to purchase my own U-bolts...When torquing down one of the u-bolts to 70 lb-ft the nut stripped all the thread off the u-bolt. U-bolt had to be cut off and replaced, tells me all the u-bolts are way too soft of metal

Libra's customer service is very good. Unfortunately they shipped my order UPS, and part of it went missing.UPS out of Las Vegas is terrible. No local customer service available, no live bodies to talk to which I think is unethical.I am telling all of my suppliers not to use UPS to ship me stuff anymore..... and if they do, I will drop them as a supplier.A seller like Libra was excellent to deal with, and UPS makes them look bad. NO MORE UPS!!!

Not the exact part for my trailer but i made them work. Trailer sits a lot higher then before on the old springs.

The leaf spring kit was awesome, but…..The U-Bolts were subpar. When I torqued to spec, the threads stripped out. I had to get different ones to replace.
