Like many of our other IFS suspension systems for the Chevys, this 4.5" system is packed with the same features and benefits of the current 6.5" kit but designed for a lower lift height for those looking for a more modest setup. Like the 6.5" system, the 4.5" includes one piece crossmembers, differential drop brackets, ductile cast iron steering knuckles and bolt-on no torsion bar drop brackets that keep the torsion bars in the factory location at the frame. Also included are stainless steel front brake lines, extended sway bar links and differential skid plates. The front replacement steel splash guard with the BDS logo finishes out the front of the clean, high clearance design. In the rear, the system comes with a 2" block and u-bolt setup that levels the vehicle perfectly. For those looking for a little more height in the rear, the existing 3" rear block kits can be substituted in..
