QA1 RCK52471 Proma Star Rear Coilover Conversion Kit Double Adjustable 550 lb/in

Transform your 1997-2013 Corvette C5/C6 rear suspension with the QA1 RCK52471 Proma Star coilover conversion system. This complete kit replaces the factory transverse leaf spring setup with a modern coilover design, delivering exceptional handling performance, suspension tunability, and adjustable ride height control.

Key Features:

• Double-adjustable design with 18 compression and 18 rebound settings (324 total valving combinations)
• Firm 550 lb/in spring rate engineered for track-oriented applications
• 8-inch shock body length with 2.25-inch ID springs
• Adjustable ride height: lower base models 1-2 inches, Z06 models 0.5-1.5 inches
• Aluminum construction with powder-coated finish for corrosion resistance
• Bolt-on installation using factory mounting points with basic hand tools
• No toe link relocation kit required
• Made in USA, serialized, and dyno-tested
• Limited lifetime warranty when registered at qa1.net/warranty

The firm spring rate option is ideal for enthusiasts who demand maximum performance on track days while maintaining excellent street manners. Independently adjust compression and rebound valving to dial in your perfect ride quality, reduce body roll during hard cornering, and achieve a more planted, confidence-inspiring feel through corners. The threaded shock body allows precise ride height adjustment for improved center of gravity and corner balancing capability.

Installation Note: Corvettes equipped with electronic ride control require Real Time Damping simulators (sold separately).
