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

Installed them in the cockpit of a 2007 Chevy Silverado 1500 LT with a 3.5" leveling kit and the truck looks great! It looks leveled and slightly raised without the need to purchase a lift kit.

I installed these on my truck a few years ago along with a Readylift 2.25 inch leveling kit. It retained a slight tendency to tow, which is what I wanted. It was a bit fun with the very long threads on the U-joints, but overall installation was easy.

Excellent quality. Solid blocks and bolted fittings. My complaint would be the length of the U-bolts. I ordered a 3" blockset. I could mount a 6" with the screws provided. You should cut them off unless you want the large stems to hang down under the truck. A job I didn't expect. Otherwise a good sentence.

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…
