Base Valve Medium

The Base Valve Medium from QA1 is a precision-engineered shock component designed for performance suspension systems that demand refined damping control. This valve assembly is essential for builders and enthusiasts upgrading to adjustable coilover setups or air suspension platforms. It is particularly suited for high-performance applications requiring tunable compression and rebound characteristics.

The Base Valve Medium serves as the foundation for custom shock tuning, allowing users to dial in the exact hydraulic response needed for their vehicle's intended use. QA1's engineering delivers micro-precision valve internals that manage fluid flow rates through the shock's compression circuit with minimal friction and maximum consistency. Constructed from high-grade steel and precision internals, this valve resists cavitation and maintains stable performance through extended heat cycles.

Professional suspension tuners, DIY performance builders, and customers upgrading their QA1 shock systems will benefit most from the Base Valve Medium. Its compact form factor—measuring 2.85 x 0.7 x 3.5 inches and weighing just 0.07 lbs—integrates seamlessly into tight shock body configurations. This valve is ideal for achieving balanced suspension geometry across a wide range of vehicle weights and spring rates.
