The 6061-T6 alloy shock absorbers filled with oil (Injected with 1000cSt silicon oil) and sealed cover,which is durable and has a good resistance effect.
The black progressive spring installed on the shock absorber（wire diameter of 1.2mm）. GPM will also include an additional silver progressive spring（1.3mm wire diameter） in the package, which can be replaced according to your own needs
The front or rear shock absorber centre distance is 63mm, the shock shaft is thickened from the original 3.0mm to 3.5mm, and it is more wear-resistant when stretched back and forth, and not easy to bend and break.
Progressive spring design, more dynamic adaptability, spring stiffness changes with load (soft first and then hard), can better adapt to different road conditions or load conditions.
