63 Series Shock 7in Front 5C/650R

The QA1 63 Series Shock 7in Front 5C/650R is a premium twin-tube front suspension shock designed for high-performance vehicles that demand precise damping control and durability. Built for enthusiasts and professional tuners who require adjustable compression and rebound characteristics, this front shock delivers the responsiveness needed in street, strip, and road course applications. The 7-inch stroke paired with a 13.38-inch compressed length and 20.30-inch extended length makes it ideal for vehicles with limited suspension travel or aggressive stance requirements.

This shock features a robust twin-tube design with a 2.00-inch outer diameter tube, engineered to handle sustained performance demands while maintaining consistent oil flow and heat dissipation. The 5-position linear compression adjustment allows fine-tuning of impact absorption across varying road conditions, while the 650-digressive rebound setting progressively controls extension forces—critical for preventing bottoming and maintaining tire contact during aggressive driving. The threaded aluminum construction with black anodized finish resists corrosion and provides a lightweight yet rigid platform, reducing unsprung weight while enhancing durability in both wet and dry environments.

Professional builders and performance-focused drivers benefit most from this QA1 shock when upgrading suspension geometry or implementing coilover systems on street cars, drag racing platforms, or autocross competitors. Installation is straightforward when integrated into a complete suspension package, and the adjustable damping characteristics allow real-time tuning without component replacement. Sold individually, this front shock pairs with a corresponding rear unit to create a fully balanced, performance-tuned suspension system capable of handling repetitive cornering, acceleration, and braking cycles.
