Like most IFS (independent front suspension) trucks, the Toyota uses upper and lower control arms supported by torsion bars. What makes the Toyota IFS suspension unique is that the torsion bars run along the top of the frame rails and connect to the upper control arms which means the torsion bars cannot be relocated.
Front lift is achieved by lowering the lower control arms via one-piece crossmember assemblies. Since the upper control arms must remain in their factory location, new precision cast knuckles bridge the increased distance between the upper and lower control arms. The front differential housing is lowered to keep CV axle angles in check, sway bar relocation brackets, bump stop extensions, brake hose and E-brake relocations brackets are also provided. The kit is packaged complete with Superlift'superide shocks.
