Stocker Star Shock- Double Adjustable

The Stocker Star Shock - Double Adjustable by QA1 is engineered for enthusiasts and mechanics who demand precise suspension control without breaking the budget on a street or strip application. This double-adjustable shock absorber addresses a critical gap in the market: affordable tuning capability for bracket racers, weekend warriors, and restomod builders who need independent compression and rebound damping settings. Unlike fixed-rate OEM shocks, the Stocker Star delivers measurable adjustability that translates to better weight transfer, reduced chassis squat, and improved lap times on the track.

QA1's double-adjustable design isolates bump and rebound circuits, allowing you to fine-tune compression stiffness independently from damping recovery. This separation is critical for dial-in work: stiffer compression controls body roll and front-end squat during acceleration, while adjustable rebound governs how quickly the chassis settles after a bump or weight transition. The Stocker Star's monotube construction minimizes heat fade during sustained driving, maintaining consistent performance across multiple passes or lap sessions. At 4.35 lbs per unit, the lightweight construction helps reduce unsprung mass—a direct contributor to improved grip and reduced tire wear during sustained cornering.

This shock is ideal for bracket racers dialing in ET consistency, street-strip dual-purpose vehicles, and classic car restorations where modern handling is non-negotiable. Mechanics and build shops appreciate the granular adjustment range, which eliminates the need for multiple shock purchases to dial in a platform. The compact 3.9 x 3.6 x 19.1 inch envelope fits most factory and bolt-on suspension locations, making retrofit installation straightforward for single-adjustable to double-adjustable upgrades. Installation and initial setup require a damping meter or baseline testing; QA1 documentation provides step-by-step tuning guidance for common platforms.
