This unique High Clearance suspension lift kit utilizes high arched crossmembers that blend perfectly with the angle of the factory installed lower control arms for a completely integrated look while lifting your vehicle a full 4-1/2" dramatically increasing ground clearance at the front crossmembers and improving operating geometry. A front differential skid plate comes standard, for increased off road protection. This system is available with two different knuckle designs. The standard knuckle widens the track, but does not affect the turning radius. The narrow track knuckle reduces the total track width change by about 1.5" overall, but does increase the turning radius slightly.

The rear is lifted with a tapered 3" block for easy installation.

This highly customizable kit gives you the choices you need to build your rig your way. Standard or narrow track knuckle kits, gas shocks, and dual steering stabilizers are just a few of the options and upgrades available for this 4-1/2" Chevy/GMC suspension lift kit.
