Readylift is proud to introduce a new SST Lift Kit system for the 2007-2011 1500-series Chevy Tahoe, Chevy Suburban and Chevy Avalanche 6-lug 2WD. Readylift's goal is to provide a true 4.0 inch lift kit that is completely bolt-on; no drilling, cutting or welding required. This system significantly increases ground clearance while allowing for tire sizes up to 33 inch tire on an aftermarket wheel. The most common tire size for this application is 33 x 12.50 (max). In order to install a 33 x 12.50 (305/55/20) with aftermarket wheels, some minor trimming of the inner fender-well may be required. This kit is designed for use with aftermarket wheels.
