2014 Denali - Dustin870
Easy Install
Gave my truck the perfect stance after pairing with RC 2” leveling struts. I’ve now got just under an inch of rake. Easy to install and no cutting required.

Good lift blocks
I needed to raise the back of the truck for two reasons. One I lifted the front 2" and wanted the back to be level but a tad higher. This made the truck level when towing.

ReadyLift 3 inch Block for Rear lift
I just had a front 2in eibach front lifted strut installed concurrently with this ReadyLift 3in block this week. The truck looks GREAT ?? The reason I chose these blocks was because I wanted to maintain some rake when lifting the truck, and it added around 1.5inches to the rear. I added some rear 0-2in rear fox adventure shocks last year, which I'm glad to say work great with the blocks, and I am now able to take advantage of the extra shock travel.

Raised just a touch
I wanted to raise the truck just a bit, so I put a leveling kit on. Wasn't happy with the look. So, I installed a 4" lift for the rear. Now the look is just as I wanted.

Sturdy
Pretty sturdy piece of block U-Bolts as well but too long if you are only using a 5 inch block, I had to cut mines to be able to use a long socket
