2000-2006 Suburban & Avalanche Tahoe 2WD / 4WD 2 inch Front / 3 inch Rear Lowering Kit (Torsion Key)

Torsion keys actually re-index the ride height down 2" while maintaining factory pre-load and spring rate.  A pair of engineered drop coils replacing the factory rear springs produce a 3" drop. Shock extenders finish out the kit by keeping the factory shocks optimized for best performance or you can upgrade the rear shocks with shock number 2000.
