Shock Cap Reservoir (GPM & Stock) - Compatible w/ XRT & X-Maxx

Front or Rear Dampers

Designed for use on both front and rear shock absorbers depending on setup and application.

Product Major Functions & Usage

Reduces friction and absorbs driving impact forces to improve vehicle stability and overall balance during operation. This component supports smoother damper response and more consistent shock performance.

7075 Alloy Front L-Shape Piggy Back Body (Built-In Piston Spring) With Shock Cap For GPM L Shape Front Or Rear Dampers (Non-Oil Filled)

Major Advantages of Upgrading to This Part/Product

(1) Constructed from high strength, lightweight 7075 aluminum alloy, offering improved durability while maintaining reduced weight. Integrated shock cap design ensures a tight seal to help prevent leakage.

(2) L-shape piggy back configuration with a built-in piston spring allows adjustable rebound characteristics, improving pressure load response and damping behavior under dynamic conditions.

(3) Compatible with both original equipment shocks and GPM shock absorber systems, providing flexible upgrade integration.

Adjustable

Rebound hardness can be tuned by adjusting the red screw located at the bottom of the negative pressure oil cylinder, allowing changes to spring damping stiffness based on driving preference and terrain conditions.
