Designed for the serious off-road adventure seeker, the all new Bilstein B8 6112 kit is the ultimate suspension solution. The Bilstein B8 6112 kit optimizes off-road and on-road capabilities with a 60mm digressive piston for increased damping control. This kit features specially designed cold wound springs and an adjustable spring seat which allows for vehicle leveling, larger tires, and increased ground clearance. The kit comes with (2) 60mm shock absorbers (2) springs and (2) billet spring seats. Bilstein B8 6112 kits are a direct bolt on for late model half-ton trucks and SUVs which utilize a front factory coilover suspension design. The Bilstein B8 6112 kit is for front applications and reuses the OEM top mount and spring isolators. To maximize performance, Bilstein recommends a B8 5160 remote reservoir shock absorber for the rear application.
