Bladders

Shock Bladders – Motorcycle Rear Shock Reservoir Membranes

Shock bladders are flexible internal membranes installed inside rear shock reservoirs to separate nitrogen gas from damping oil. This separation maintains stable internal pressure, prevents oil aeration, and ensures consistent damping performance under high-speed compression and extreme temperature conditions.

• Application: Rear shock absorbers with bladder-type reservoirs
• Function: Oil and nitrogen separation
• Purpose: Maintain consistent pressure and damping stability
• Use: Shock rebuild, service interval replacement, race preparation

Over time, bladders can harden, crack, or lose elasticity due to heat cycles and continuous pressure. A degraded bladder may cause pressure fluctuations, cavitation, inconsistent rebound/compression response, or oil contamination.

Replacing the bladder during scheduled shock service restores proper hydraulic function and improves long-term reliability. Available in various diameters and heights to match specific reservoir designs and shock brands.

Important: Confirm your shock uses a bladder-type reservoir (not floating piston) and verify exact dimensions before ordering. Professional installation and correct nitrogen recharge are strongly recommended.
