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 inch 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 inch lift. This equates to a nice all-around lift suitable for up to 32 inch 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.
