QA1's single or double-adjustable front coil-over conversion shocks feature a forged and machined aluminum shock body that has been threaded for the ultimate in ride weight adjustability. Each shock body is also clear anodized for award winning looks and durability. Specially designed conical springs come with each kit, allowing for use of the factory upper spring pocket, while the lower portion rides on plates with the shock body. Choose either single or double adjustable shocks, depending on your needs. The single adjustable series provides 24 positions that simultaneously adjusts both compression and rebound with one knob. Double-adjustable shocks offer a much wider range, with separate knobs for compression and rebound. Each set is designated by vehicle type as well as total front end weight for the best ride quality possible.
