QA1 Floating Piston - 46mm Monotube

This QA1 46mm Monotube Floating Piston is what you get when you order part number 9057-216. It's a key component for rebuilding or repairing certain monotube shock absorbers, specifically those using a 46mm body. This piston helps manage the separation of gas and oil within the shock, which is crucial for consistent damping performance.

The design of this floating piston is intended to work within a monotube shock absorber system. In these systems, the piston separates the high-pressure nitrogen gas from the shock fluid. This separation prevents aeration, which can cause shock fade under heavy use or high temperatures. A well-built piston like this one ensures that separation is maintained, leading to more reliable damping characteristics for your vehicle's suspension.
