Disc Bypass 2 Notch 8mm ID

The BILSTEIN Disc Bypass 2 Notch 8mm ID shock valve is a precision-engineered internal component designed for builders and technicians upgrading high-performance suspension systems. This valve assembly is essential for controlling hydraulic flow within BILSTEIN monotube dampers, allowing for fine-tuned compression and rebound characteristics that serious enthusiasts demand when customizing vehicle ride quality and handling dynamics.

The two-notch disc design with an 8mm inner diameter provides calibrated flow passages that meter pressurized fluid through the shock body, directly influencing how quickly your suspension responds to bumps and body roll. BILSTEIN's manufacturing standards ensure tight tolerances on the disc geometry and notch angles, which determine the valve's opening pressure and flow rate curve. This component is designed to maintain OEM-spec hydraulic efficiency while allowing tuners to swap valves and adjust compression settings without full shock disassembly or fluid changes.

Mechanics and suspension builders working on BILSTEIN B46 damper kits, motorsport applications, and high-end street vehicles will benefit most from this product. Its compact design fits within BILSTEIN's B46 and compatible monotube shock platforms, making it an ideal choice for those looking to enhance their vehicle's suspension tuning. Installation requires basic mechanical skills, making it accessible for both professionals and dedicated enthusiasts.
