Review on 🔧 Enhance Performance with Readylift 66-3003 3" Rear Block Kit - GM Silverado & Sierra 1500 6-lug, silver by Joe Medlin

Nothing could be simpler than this kit. It was easy to install with a percussion gun, but a screwdriver might take a while because U-bolts have very long threads. I found it odd that the nuts are factory set at 100 ft/lbs, I checked before removing them, but the instructions for the new nuts say 120 ft/lbs. In any case, I tightened them to 120 ft/lb with no problems. The finished lift is one of the best level kits. I am very happy with the look of my truck and there is less body roll in corners. I also purchased a front alignment kit which is recommended as a setup with these rear units. Now I'm ready for my 33 inch tires.
