Shock Steel Twin Tube 7in Comp 4 Reb 13

The Shock Steel Twin Tube 7in Comp 4 Reb 13 by QA1 is a professional-grade shock absorber engineered for serious vehicle suspension builds, restoration projects, and performance modifications. Built for mechanics and enthusiasts who demand precision damping control, this twin-tube design delivers the tuned response needed for both street and competition applications. The 7-inch compression and 4-inch rebound stroke configuration makes this shock ideal for vehicles with moderate travel requirements and aggressive driving conditions.

QA1's twin-tube construction features a robust steel housing that separates compression and rebound circuits, allowing independent tuning of both dampening curves for balanced suspension geometry. The 7-inch compression travel handles bump absorption effectively, while the 4-inch rebound circuit maintains controlled wheel recovery without harshness or wallowing. At 5.14 lbs and measuring 19 inches in overall length with a 3.75-inch mounting diameter, this shock integrates into tight engine bays while providing adequate stroke for modern suspension linkages. Twin-tube design inherently resists cavitation better than single-tube alternatives, ensuring consistent performance across extended driving sessions and temperature fluctuations.

Mechanics installing the Shock Steel Twin Tube 7in Comp 4 Reb 13 will appreciate QA1's attention to mounting versatility and construction quality. This shock suits classic car restorations, street rod builds, and modern performance platforms requiring factory-compatible dimensions with aftermarket valving. Installation requires proper spring selection and ride-height adjustment to maximize the shock's 7-inch/4-inch travel envelope. For best results, pair this unit with matching shocks on opposite corners and verify mounting clearance within your vehicle's frame geometry before final installation.
