This Toyota 4Runner suspension system features Fabtech's proven IFS technology with extended length ductile iron steering knuckles for proper electronic stability control functionality. Heavy duty 1/4in thick steel lower control arm crossmembers provide superior ground clearance while the integrated front differential skid plate adds protection to the drivetrain for offroad use. The front suspension is controlled with Fabtech's legendary stainless steel Dirt Logic 2.5 Coilovers for outstanding damping capacity with a superior highway ride. Rear lift is accomplished with steel coil spring spacers that retain the Toyota 4Runner coil springs for a smooth ride. Heavy duty Fabtech control link arms replace the factory arms to re-position the tire in the wheel well with the additional ride height. A stout 1/4in thick steel bracket relocates the rear Track Bar to keep the vehicle tracking proper. Rear shocks include the Dirt Logic 2.25.
