QA1 GD501-10400A Front Coil-Over System | Double Adjustable Shocks, 400# Springs
Item Description


Application: 1964-1967 GM A-Body - Chevelle, Malibu, GTO, etc.

Part# Q-GD501-10400A

Easy Bolt-In Installation!
Remove the existing front shocks and springs and the QA1 Pro Coil System bolts right in.

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.

Double Adjustable Shocks
Aluminum shocks with 324 valving options. Allows truly independent adjustment of compression and rebound. 18 positions of compression adjustment on one knob, and 18 positions of rebound adjustment on the other knob. Each knob is clearly labeled with an "R" for rebound or a "C" for compression, as well as plus and minus symbols for ease of adjustment.

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

The QA1 Pro Coil System Includes:

(2) QA1 Proma Star 18 way double adjustable coil-over shocks
(2) Conical springs
All required mounting hardware
