Using the cushioning principle of high-end cars, the shock absorption performance of the vehicle is significantly improved, and the ride is more comfortable. Effectively solve the problem of the weak spring of the shock absorber, restore the elasticity of the shock absorber; improve the stability of the car in sharp turns, non-sluggish roads, and uneven roads; protect the shock absorber and suspension system from oil leakage from the shock absorber; test results It can extend the life of the shock absorber by more than 2 times and reduce the driving noise.
