Readylift 66-3003 3" Rear Block Kit - GM Silverado & Sierra 1500 6-lug, silver

You can't get any easier than this kit. It was easy to install with an impact gun but wrenching could take some time because the U bolts have really long threads. I thought it was odd how the manufacturer's nut torque setting was 100ft/lbs, I checked before taking them off, but the instructions stated 120ft/lbs for the new nuts. Either way, I torqued them down to 120ft/lbs with no problem. Ready lift makes some of the best level kits. I am extremely happy with the way my truck looks and there's less body roll around corners. I also bought the front leveling kit that's recommended with these rear blocks as a setup. I'm now ready for my 33inch tires.

I put these on my truck a few years ago to go with the 2.25” leveling kit from Readylift. It kept a slight rake for towing, which is exactly what I wanted. Had some fun with the super long threads on the U-joints, but it was a simple install overall.

The box was damaged and the product was used. In addition the U-bolts are stripped.

Great looking. Easy install

I installed these on my 2014 chevy silverado along with the front leveling kit. These blocks worked great the quality is excellent. They were easy to install and didn't effect ride quality at all.

Nice blocks! Made and fit just like OEM.The only pain in the A was the u-bolts are way way too long.Which means you cant tighten them with a deep well socket.Have a sawzall or cutoff wheel handy.

Great extra lift to maintain the factory rake after installing a front leveling kit. Includes all required hardware.

Missing most important part
