QA1 RCK52470 Proma Star Rear Coilover Kit Double Adjustable 450 lb/in Medium Spring

The QA1 Precision Products RCK52470 Proma Star Pro Coil System transforms your 1997-2013 Corvette C5 or C6 from outdated leaf spring rear suspension to a modern, fully adjustable coilover setup. This conversion improves handling, suspension tunability and ride quality while gaining the ability to quickly and easily adjust ride height.

Double Adjustable Performance:

The double adjustable design offers independent compression and rebound valving adjustments with 324 total valving options (18 compression positions and 18 rebound positions). This rear coilover kit offers the perfect balance of street-ability and performance for cars used on the road and occasionally at the track.

Adjustable Ride Height:

• Lower base model Corvettes 1 to 2 inches
• Lower Z06 models 0.5 to 1.5 inches
• Improve handling by lowering center of gravity
• Enhanced corner balancing capability

Medium Spring Rate for Street Use:

The medium 450 lb/in spring rate is ideal for daily street use, providing a comfortable yet controlled ride. Multiple spring rate options are available for different applications, with firmer options suited for track-oriented performance.

Easy Installation:

These coilovers install easily with basic hand tools using factory mounting locations and do not require a toe link relocation kit. Models with electronic ride control require Real Time Damping simulators.

Quality Construction:

QA1 shocks are made in the USA, serialized, dyno tested and eligible for a limited lifetime warranty. Each kit includes a pair of aluminum double adjustable rear coilover shocks with springs. Register your purchase at qa1.net/warranty before installation to activate warranty coverage.
