Shock Absorber using imported steel from Germany, the shock absorption durability can reach 5-7 years without any problems such as hardening/oil leakage/abnor mal noise/deformation. Effectively improve the cornering and inclination, winding road, sharp turning, more safe and stable, better reduce the body bump and vibration at the same time , enhance driving comfort. Meanwhile, it can reduce bumpy jitter and enhance driving comfort. The surface is painted by deep electrophoresis to ensure smooth surface, acid rain corrosion resistance and good oxidation resistance. The high strength piston rod imported advanced TRIP imported materials, through advanced special technology one-time forming, to ensure the shock absorber piston rod is strong and wear-resistant, low friction and noise-free, and better metal fatigue resistance.
