The True Travel Dynamics long travel kit for 4WD Silverados and Sierras 1500 trucks is built tough to handle all types of off-road terrain. Our kit eliminates the factory torsion bars and utilizes a 2.5″ x 8″ coil-over shock and 2.5″ x 8″ bypass shock giving you more control over dampening and a far better ride. Since our kit is a total of 9″ wider than stock you’ll also need longer axles. Our axle set utilizes custom made CV adaptors to be able to use a 930 CV joint on the inner side to give you more articulation which translates into more wheel travel.
If you want 16″ of wheel travel with 4WD, more strength and a better ride then our Silverado/Sierra +4.5″ 4WD kit is exactly what you need.

Please note this kit does not fit 2500 or 3500 HD trucks
