QA1 has added a new line of front coilover Pro Coil Systems for owners of 1971-1996 full-size GM vehicles such as full size Chevy, Buick, Oldsmobile and Pontiacs that are looking for fully adjustable ride height and valving control. Choose from double, single or Drag “R” Series.

Official Release:

QA1 has expanded its line of front coilover Pro Coil Systems to include 1971-1996 full-size GM vehicles, including Full Size Chevy, Buick, Oldsmobile and Pontiac models. These kits are ideal for drivers of Impalas and other Full Size GM vehicles who are looking for fully adjustable ride height and valving control.

QA1 Front Pro Coil Systems include adjustable aluminum shocks, high travel springs and all necessary mounting hardware. These shocks have a threaded body that allows the car to be lowered from stock ride height to -2 inches while on the car. This allows you to get the stance exactly where you want it for your driving style or wheel and tire combination. Multiple spring rate options are also available to choose from for casual street driving to hardcore autocrossing or drag racing.

Choose from double, single or Drag “R” Series adjustable valving options to get the ride you want. The double adjustable shocks provide 18 positions of independent compression adjustment and 18 positions of independent rebound adjustment for a total of 324 possible valving combinations. Single adjustable shocks provide 18 positions of simultaneous rebound and compression adjustment. The Drag “R” Series shock provides 18 levels of simultaneous adjustment while maintaining a “90/10” style valving in each adjustment, allowing the front of the car to rise easily and come down softly for a smoother, more controlled launch.

QA1 offers both front and rear coilover systems for many vehicles. All QA1 aluminum shocks are made in their Lakeville, Minnesota facility, are 100% dyno tested and serialized and are rebuildable and serviceable by QA1 Authorized Service Centers.
