Shock Steel Twin Tube 7in Comp 5 Reb 13

The Shock Steel Twin Tube 7in Comp 5 Reb 13 is a high-performance twin-tube shock absorber designed for street and strip vehicles that require precise damping control and extended ride height capability. Built by QA1, a trusted name in suspension engineering, this 7-inch shock provides the tuning flexibility that serious enthusiasts demand when upgrading factory suspension geometry or tackling track-focused builds.

With its twin-tube construction and 7 inches of physical length, this shock delivers the compression and recovery characteristics needed for both highway cruising and aggressive cornering. The design helps prevent temperature-related performance fade by separating the piston rod from pressurized fluid, ensuring consistent damping across extended drives or track sessions. Weighing 5 pounds, this shock balances durability with unsprung weight savings, which is critical for those working within tight package constraints or pursuing weight reduction goals.

The 13-unit designation refers to QA1's internal valving matrix, specifically tuned for vehicles with moderate to stiff spring rates and ride height applications up to 7 inches of travel. This shock is best suited for double-A-arm or coilover-equipped vehicles, where the 7-inch envelope and twin-tube geometry fit well, allowing for optimal chassis dynamics and performance.
