Product Description

Tuff Country 4-inch Rear Block & U-Bolt Kit for 2006-2023 GMC Sierra 1500 4WD models. This rear lift kit uses cast-iron blocks installed between the factory rear leaf springs and axle, along with application-specific extended zinc-plated U-bolts.

Application: 2006-2023 GMC Sierra 1500 4WD.
Rear lift: 4 inches at the rear axle. This is a rear leaf-spring suspension kit, not a front-axle component.
Construction: Cast-iron rear blocks. The blocks fit between the factory leaf springs and rear axle to add height.
Included hardware: Rear lift blocks and extended zinc-plated U-bolts sized for this application.

A rear block kit is useful when you're matching the rear height to your Sierra's suspension setup for daily driving, worksite miles, towing, or occasional trail use. Confirm your truck's year, 4WD configuration, and current suspension setup before installation.

Custom, Forged, or made-to-order wheels: Typically take 12-16 weeks to arrive.
Wheel & Tire Packages: Usually delivered in 10 - 14 business days (freight delivery, signature required).
FAST and FREE Shipping wheels, tires, and packages: FREE freight shipping to the lower 48 states.

Multi-item orders may arrive in separate shipments depending on the warehouse location. Tracking info will be provided as soon as items ship.
