Reviewer: Charley Brown (McKenzie, TN)

This kit is absolutely "Heavy-Duty" and the quality has to be second to none! Dan at RuffStuff shipped the parts out quick and we had a great line of communication throughout my order process. I will not hesitate to order from him in the future.

Wow! Wasn't expecting the kit to be so beefy, quick shipping, ordering was easy. The processing my order took the longest. I am very pleased at the quality of the craftsmanship, and would buy or recommend this to friends. And on a side note, love the little metal RUFFSTUFF logo!

Reviewer: Darren Lee (Waterford, Ontario)

I bought a simple swap for my Ford Explorer 8.8" 31 spline axle. Upon receiving the kit I can see why USPS wants so much to ship these from NorCal to Southwestern Ontario Canada. This kit is built for serious abuse. If you own a Ford Ranger, Bronco II, Jeep CJ/YJ, S-dime or anything else that has leaf springs and needs them over the axle you need this kit. I can't wait to get my 2000 Ranger std cab/flareside 4x4 rolling with a 31 spline 8.8" with disk brakes and a lsd.

Reviewer: Shawn Powers (South Euclid, OH)

Holy hell! This is one beefy kit. My axle will surely break long before any component of this kit. Excellent quality. I have a new favorite parts supplier.
