1964-1967 GM A-Body QA1 “R” Series Pro Coil-Over System

Description

These R Series Pro Coil systems from QA1 are engineered just for drag racing. Their R Series shocks offer firm compression with a wide range of rebound adjustment for front drag racing applications. Also featured are specially designed conical springs that allow the use of a longer and lighter spring for more stored energy and increased weight transfer.  The QA1 R Series coil over system replaces the factory shock and spring while adding ride height adjustment and reducing front end weight by 10lbs. This kit is a bolt on application and requires no modifications to complete installation.

The R Series Pro Coil Over System includes:

• (2) R Series coil over shocks
• (2) Specially designed conical springs

Spanner Wrench- Spanner wrench tool is used to adjust vehicle height while shock stays mounted. This wrench is needed to make height adjustments.

Thrust Bearing Kit- Thrust bearing kit is designed to be placed between the spring and the spring seat attached to the shock. This makes for easier adjustments since the spring seat is rotating on a bearing. This kit is recommended for easy adjustments but is not needed to complete the installation.
