Shock Rear GM Monotube 12-2 valve w/Hyperscrew

The QA1 Shock Rear GM Monotube 12-2 Valve with Hyperscrew is a performance suspension upgrade designed for serious enthusiasts and builders who demand precise damping control in their GM vehicles. This monotube shock absorber addresses the limitations of factory rear suspension by delivering adjustable damping through its proprietary 12-2 valve configuration, making it an ideal choice for street machines, drag cars, and vehicles experiencing harsh ride quality or excessive chassis roll.

The monotube design eliminates the traditional twin-tube architecture, replacing it with a single pressure tube that houses both the piston and floating separator. This engineering approach minimizes fade under sustained heat and maintains consistent damping force during aggressive driving or racing conditions. The integrated Hyperscrew adjuster enables on-vehicle fine-tuning without removal, a feature that distinguishes purpose-built shocks from basic components.

Constructed to withstand shock loads common in performance driving, this unit is designed for straightforward fitment into most GM rear suspension applications while maintaining proper ride height and geometry. Whether you're tuning a classic Chevelle, modernizing a Camaro, or perfecting a custom build, this shock provides the foundation for a properly controlled suspension geometry.
