Description
Check valves are critical flow-control components in high-performance suspension systems, directly influencing damping characteristics and ride quality. A worn or incorrectly sized check valve compromises shock performance and can lead to unpredictable handling on track or street. The Bilstein Disc 31/20 ensures precise pressure regulation and consistent damping response across your entire suspension package.
