Description
Provides a 1-Inch Lift. Put a slight rake on your truck by installing this ReadyLIFT 1-Inch Rear Lift Block Kit. This kit provides an additional 1-inch lift to your vehicle’s rear, which then helps improve its hauling capabilities. Even if your truck bed is loaded with heavy cargo, its rear end won’t sag and hit the ground, keeping its components safe.
Durable Cast Iron Rear Lift Blocks. To lift your truck’s rear, this kit comes with rear lift blocks. These components are made of cast iron, making them stronger than the standard lightweight extrusions. What’s more, these blocks sport an OEM style, allowing for easy and direct fitment.
With E-Coated and Longer U-Bolts. This rear lift block kit comes with e-coated and longer U-bolts. With their e-coating, the U-bolts can resist rust and maintain their pristine condition for a long time. Meanwhile, their longer build allows them to match the new height of your truck and provide improved handling characteristics.
Direct Installation. Setting up this rear lift block kit is easy for anyone with some mechanical expertise. This kit’s components are built with a bolt-on design, so you can directly mount them to your vehicle’s existing points.
Supported by a Lifetime Warranty. This rear lift block kit is supported by a lifetime warranty, so you can be assured of its quality. But in case your purchased item exhibits any factory flaws, you can return it and have it repaired or replaced. Terms and conditions apply.
Application. This ReadyLIFT 1-Inch Rear Lift Block Kit is made 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.
