The ReadyLIFT 2" Rear Block Kit raises the rear of the truck on its leaf springs. One taller block per side replaces the need to stack blocks. ReadyLIFT kit 66-3122 is engineered for the 2011-2024 Chevrolet Silverado 2500 HD and Silverado 3500 HD and GMC Sierra 2500 HD and Sierra 3500 HD.

What's Included:

Alignment, headlamp aiming and ADAS recalibration are not included.

Features

Rear lift for leaf springs
The kit raises the rear of leaf-spring trucks and is sized for each application.

Puts back towing rake
A slight rear rake helps a truck sit level once a trailer or a heavy load is on board.

Based on OEM designs
ReadyLIFT bases its blocks on factory designs and builds them from cast iron or fabricated steel, not lightweight extrusions.

No stacked blocks
A single taller block per side avoids stacking blocks, a practice ReadyLIFT notes may be illegal in some states.

Pairs with front leveling
The kits are designed to work alongside ReadyLIFT leveling kits, adding rear height to match a raised front.
