Our Tundra systems feature extended length ductile iron steering knuckles that have been designed to operate within the factory steering geometry. This geometry provides proper turning radius with oversized tires and wheels. The factory lower control arms are relocated with high arched 1/4in thick steel crossmembers with an integrated differential skid plate for protection against offroad obstacles. The factory front sway bar is retained and utilizes sway bar drops. The Basic system features a heavy duty shock spacer system that retains the stock coilover shocks without disassembly for a factory like ride. This system utilizes a 3in block and u-bolt system for rear lift. Includes rear Stealth Shocks.
