Shock Alum Twin Tube 7in Comp 4 Reb 4

The Shock Alum Twin Tube 7in Comp 4 Reb 4 by QA1 is a professional-grade suspension shock designed for serious vehicle builders and off-road enthusiasts who demand precision damping control. Built for custom chassis work, circle track racing, and high-performance street applications, this aluminum twin-tube shock delivers the tuning flexibility needed to dial in your suspension geometry precisely. Whether you're building a bracket racer, street rod, or competition truck, this shock's modular compression and rebound settings allow you to match your exact suspension requirements without compromise.

This shock features a 7-inch stroke length with independent 4-way compression and 4-way rebound adjustability, giving you granular control over damping rates across the suspension's full range of motion. The aluminum body construction reduces unsprung weight compared to traditional steel designs, improving responsive handling and reducing tire deflection during aggressive cornering or acceleration events. Twin-tube design inherently offers better heat dissipation and consistent performance throughout extended driving sessions, critical for maintaining predictable handling on the track or trail. The modular adjustment system allows mechanics and suspension tuners to fine-tune performance without disassembly, saving installation time and enabling quick setup changes between runs or events.

This QA1 shock pairs well with coilover kits, custom A-arm suspensions, and independent front end conversions common in circle track and street rod applications. Installation typically requires custom mounting brackets matched to your specific chassis geometry and suspension design. The lightweight 4.19 lb construction makes this ideal for weight-sensitive builds where every pound counts toward performance, particularly in competition vehicles where mass reduction directly impacts acceleration and braking performance. Consult your suspension tuner or chassis builder to ensure proper valving selection and installation for your intended application.
