QA1 Economy Pro Coil-Over Conversion System - Drag Racing

Easy Bolt-In Installation
Minimal modifications to be made. Remove the existing shocks and springs and QA1 Economy Pro Coil System bolts right back in.
Specially Designed Conical Springs
This spring is designed so that the lower end sets on the coil-over shock and the upper end sets in the original spring bucket in the frame. This allows for the use of a longer and lighter spring for more stored energy, offering increased weight transfer. Greater durability and safety is also achieved by locating the spring pressure in the frame and not on a single stud.
Ride Height Adjustable
Steel body allows ride height adjustment. Allows up to 3" lowering of car.

The QA1 Economy Pro Coil System uses the Economy Stocker Star® shocks as the foundation. The Economy Pro Coil System includes:
(2) Economy Stocker Star® shocks
(2) specially designed conical springs. Spring rates vary based on application
All mounting hardware

For drag racing applications (300-350lb. springs)
