Specially Designed Conical Springs
These springs are designed so that the lower end sits on the coil-over shock's adjustable spring seat and the upper end sits in the original spring pocket in the frame. This allows for the use of a longer and lighter spring for more stored energy, offering increased weight transfer. Greater durability is also achieved by locating the spring pressure in the frame and not on a single stud.

Ride Height Adjustable- The threaded aluminum shock body allows for easy on-the-vehicle ride height adjustments.

(2) QA1 Proma Star 18 way single adjustable coil-over shocks Note our listing states 12 way
