Description
Better Hauling Performance. Equipping your truck with this ReadyLIFT 4-Inch Rear Lift Block Kit will help improve your truck’s hauling performance. With this installed, your truck’s rear will be able to achieve an extra 4-inch lift. The increased ride height prevents your vehicle’s rear from sagging, giving you greater confidence in hauling big and heavy cargo.
Features Cast Iron Rear Lift Blocks. This kit’s rear lift blocks serve as your vehicle’s primary lifting components. These lift blocks are crafted based on OEM designs but instead of lightweight extrusions, ReadyLIFT made these blocks out of cast iron. With this material, the blocks can exhibit incredible toughness, allowing them to lift and support the weight and load of your truck without breaking.
Comes with Longer U-Bolts. Unlike standard rear lift block kits, this kit comes with longer U-bolts. Having a longer build allows the U-bolts to match your vehicle’s new ride height, resulting in better handling characteristics. Furthermore, these components have an e-coated finish to prevent rust and maintain their pristine condition for a long time.
Bolt-On Installation. Setting up this rear lift block kit is made easier with its bolt-on components. Using simple garage tools, you can directly mount each piece to your truck’s factory location points. No difficult modifications are required.
Covered by a Lifetime Warranty. For your assurance, this rear lift block kit is covered by a lifetime warranty. When filing a warranty claim, please present your proof of purchase and include the details on how your purchased item got damaged. You may also be required to return the defective item for inspection and verification.
Application. This ReadyLIFT 4-Inch Rear Lift Block Kit is created to fit 2011-2019 GMC Sierra 3500 HD models.

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

Perfect!
I had already installed the Bilstein leveling struts at the highest setting and lost all the rake the truck had. In my case, the nose looked higher than the rear. These lift blocks were the ticket! Great quality and easy install.

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.
