The Alpha 4" kits are intended for the customer looking for a comfortable street ride, excellent towing authority, and a stable rearend for higher hp platforms.
The Alpha series for the 1999.5-04 trucks is designed around improving the characteristics of the stock springs. The front end receives a shackle and hanger lift. The longer shackle allows the stock spring to flex easier and in turns improves the ride quality. In the rear, we supply a shackle flip kit to again soften the ride of the oem spring. With the Alpha Series, the rear spring will be supplemented with a traction bar kit to give it a stable base when towing or any other performance scenario.Trackbar:
