Valve Disc 8pk 1.300 OD x .012in

The QA1 Valve Disc 8-pack (1.300 OD x 0.012 in) is a precision shock tuning component engineered for adjustable suspension systems that demand fine-tuned damping control. These steel discs function as flow restrictors within shock absorber valve stacks, allowing technicians and builders to dial in compression and rebound characteristics with repeatability and precision that fixed-orifice designs cannot match.

Each disc measures 1.300 inches in outer diameter and 0.012 inches in thickness—specifications that directly control oil flow rate through the valve. The eight-piece set enables builders to stack discs in various combinations, creating custom damping curves tailored to vehicle weight, spring rate, track conditions, and driving style. Steel construction ensures dimensional consistency and resistance to deformation under the high pressures generated during compression and rebound cycles. This is the standard approach used in high-performance and race-oriented shock tuning, where millimeter-level adjustments to valve stack geometry translate to measurable changes in handling balance and comfort.

These discs are intended for users rebuilding or servicing QA1 adjustable shocks, or for suspension shops and enthusiasts who work with modular valve systems. Applications range from road-course racing and autocross to off-road competition and street performance vehicles. Proper disc selection requires understanding spring rates, ride height, and intended use; incorrect stacking can compromise both comfort and control. QA1 recommends consulting suspension geometry and shock tuning guides specific to your vehicle platform before modifying valve configurations.
