ReadyLIFT is proud to offer a SST Lift Kit system for the Chevy Colorado 2WD/4WD (Torsion bar) pickups and Hummer H3.  Using ReadyLIFT’s popular engineering methods, our research and development team released a true bolt-on, no modifications required, front and rear lift kit system for 2004-2012 Chevy Colorado pickups.  The front of this popular truck receives a 2.25″ lift in front using the ReadyLIFT adjustable torsion keys. To lift the rear, new rear leaf spring shackles are included which provide a 1.5″ lift. This equates to a nice all-around lift suitable for up to 32″ tall tires while providing a bit of a rake to towing or hauling.  In addition to the highest quality torsion keys and shackles on the market, this kit also contains front and rear shock extensions so you will not have to change your stock shocks.

Tire Size Note: ReadyLIFT wheel and tire fitment recommendations are typically based on Wheel Pros wheels and Nitto tires. Due to product differences among tire manufacturers, tire specifications and dimensions including, but limited to, overall diameter, rolling diameter, tread width, aspect ratio, lug pattern, sidewall construction and inflation pressure, will vary meaningfully by tire and wheel manufacturer. Every tire and wheel combination should be test fit prior to installation. Consult your local installer to learn more about the right tire fitment for your application.

Ride Quality Note: When lifting a vehicle and installing aftermarket wheels and tires, a tire manufacturer’s construction and material quality can alter vehicle ride quality. When increasing a vehicle wheel and tire size, most larger aftermarket truck and SUV tires are 10-ply (or more) E tires compared to typical OEM 6-ply C tires. This more rigid sidewall construction increases the perception of suspension stiffness often described as ride harshness. The ride, handling, traction, noise, fuel economy, and wear differences between All-Season, All-Terrain, Mud-Terrain, or Trail-Terrain type tires can be significant. Please take into account tire and wheel choice will generally have a meaningful impact on the ride & handling experience.
