63 Series Shock 7in Front 5C/400R

The QA1 63 Series Shock 7-inch front suspension component delivers precision damping control for vehicles requiring independent front suspension tuning. This 7-inch stroke shock features a 5-rate linear compression curve paired with 400-weight digressive rebound valving, engineered to balance ride compliance with responsive handling across varied driving conditions. The twin-tube design with threaded aluminum body and black anodized finish provides durability in both street and competition environments.

The 13.38-inch compressed length and 20.30-inch extended length accommodate typical front suspension geometry in street rods, muscle cars, and vintage performance builds. The 2.00-inch outer diameter housing integrates with standard shock mounts and control arm brackets. The 5-weight linear compression rate provides progressive load support as the suspension compresses, while the 400-weight digressive rebound prevents oscillation and settling time. This combination creates stable cornering behavior and controlled spring extension without excessive harshness on road imperfections.

QA1 shocks are favored by builders who require application-specific damping without the cost of full custom valving. The 63 Series suits front-end installations where independent tuning from the rear shock is desired—common in dual-purpose vehicles that see both highway cruising and autocross duty. The threaded body allows for ride height adjustments when paired with compatible coil-over applications, offering flexibility in suspension geometry setup.

Sold individually. Verify compatibility with your vehicle's suspension architecture, control arm design, and desired ride height before ordering. This front shock pairs with a matching rear unit for complete suspension control.
