6" Standard Series Knuckle Lift System

The systems were modeled using the most current computer design software, allowing our engineers to tweak each component for optimum performance, thus ensuring that the various sub-systems work in concert to create the absolute best lift products available for the ½-ton GM. Superlift’s replacement knuckle systems install quick and easy. Also, the vehicle can be returned to stock later if desired.

Superlift offers three rear lift solutions for pickups: tapered blocks, a block / add-a-leaf system, or replacement rear spring packs. The SUVs utilize replacement coils for rear lift. Shock options include: Superide (gas front, hydraulic rear), Superide Select Series (SS) high-pressure monotube gas-charged shocks produced for Superlift by Bilstein, or SSR remote reservoir gas monotube shocks.

The Standard Series system is designed to outperform the competition, and priced to be the value leader.
