QA1 Precision Products HD06 Proma Star Coilover Strut

The QA1 Precision Products HD06 Proma Star strut is a high-performance coilover strut designed for 1982-1992 GM F-body vehicles, including Chevrolet Camaro and Pontiac Firebird. This inverted-design strut delivers superior handling and performance for both street and race applications.

Key Features:

• Inverted cartridge design with large diameter shaft resists side loading for consistent performance during hard cornering and braking
• Lightweight aluminum body reduces unsprung weight, improving suspension responsiveness and handling
• Adjustable ride height capability (0" to 2" lower than stock)
• Available in single or double-adjustable valving configurations
• Compatible with QA1 lightweight aluminum caster camber plates for precision suspension tuning
• Bolt-in installation for hassle-free setup
• Proudly made in Lakeville, Minnesota, USA

The HD06 strut series offers custom-tailored spring rate and valving packages to achieve the ultimate level of ride quality, performance, and stance for third-generation F-body platforms. The inverted design provides smoother, more consistent damping characteristics while the aluminum construction keeps weight to a minimum for improved suspension response and traction.
