What are lift blocks?
Lift blocks raise a vehicle's back end. As you might expect from their name, they're a block that adds extra space between the leaf spring and the axle. Drivers use lift blocks to raise the backs of their vehicle either for cosmetic reasons or to provide some practical benefits like making more space for larger wheels or adding extra clearance space.

Installation

1.Inspect your lift block kit:

In your lift block kit, you should have the U-bolts, nuts and, of course, the lift blocks. Ensure that all of the parts you've purchased are there, while also checking to see the proper lift block for your vehicle.

2.Chock your front wheels:

You don't want your vehicle moving while you install your lift blocks. Since you'll be removing your rear wheels from the truck, you need to chock the front wheels so the vehicle doesn't move when you lift the rear.

3.Lift vehicle and remove rear wheels:

After securing the front wheels, you can then raise your vehicle off the ground and remove the rear wheels to access the area where you're going to place your lift blocks. Use a jack stand to keep the truck steady while you install the lift blocks.

4.Unbolt and lower rear axle:

The next step of the process is removing the nuts and U-bolts of the rear axle. Next, you lower your rear axle until you have space between your axle and the leaf spring.

5.Install lift blocks:

After you've made enough space for your lift block to fit, center your lift block using the two holes on the axle's top plate.

6.Complete installation:

With your blocks now centered and in the proper position, you'll lift your axle again. You'll bolt your lift block, axle and spring back, tightening the bolts to the manufacturer's specs. Finally, reinstall your wheels and lower the vehicle to the ground.
