The QPQ Technology

We integrate surface treatment—the QPQ (Quench-Polish-Quench) Compound Treatment—to transcend the limitations of conventional chrome plated rods:

Extreme Wear Resistance: The QPQ surface boasts exceptional hardness, dramatically reducing the coefficient of friction against seals and bushings. This translates to smoother damping action, minimal friction loss, and a service life extended multiple times!

Ultimate Corrosion Immunity: Fully impervious to sweat, mud, road salt, and harsh cleaning agents. Even in the most demanding, wet, or aggressive off-road environments, your damping rod maintains peak performance indefinitely.

Aesthetic and Structural Integrity: The distinctive, high-end matte black finish is the visual signature of a deep nitriding hardening layer, providing robust structural support from the inside out.

Advantages OF Damping Rod

Damping rods with a diameter range from Ø6mm to Ø30mm, we provide a precise fit for virtually all fork types and sizes (MTB, E-Bike).

Exceptional Tthe QPQ layer maintains its stability, effectively preventing damping fade.

Reduced Friction: Ultra-smooth surface (Ra ≤ 0.2μm) minimizes seal wear
