The 6061-T6 alloy shock absorbers filled with oil (Injected with 350cSt silicon oil) and sealed cover,which is durable and has a good resistance effect.
The original spring wire diameter is 1.0 mm, The black progressive spring installed on the shock absorber(wire diameter of 1.0mm)
The front or rear shock absorber (centre distance is 89mm), the shock shaft is thickened from the original 3.0mm to 3.5mm.
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.
