Compatible: The appearance of the shock absorber is circular with an opening, there are grooves on the upper and lower sides (to place the coil springs), and there are nine oval shock absorber holes inside. According to the standard specifications of the spring spacing, the rubber buffer is divided into eight standard models: A+, A, B, B+, C, D, E and F, which can cover most spring suspension models in the world. Package Content: Model E Two. Durable and Environmentally Friendly: The buffer rubber is made of high quality imported TPE, which is wear resistant and durable. Our decorative bows are sleek and streamlined for a more sophisticated look. The inner and outer edges of the cutting surface are high and low, the outer edge is high, and the inner edge is low, which makes the installation more convenient. Bubble Shock Absorption: The rubber pad has a hole of specially designed oval stamp. A new type of buffer product designed according to the principle of neutral dispersion of impact force, which can greatly reduce the impact force in all directions. The shock absorption performance is obviously improved, which limits the vibration of the road surface during driving and reduces the vibration of the car. Stability: When using unpaved roads, bumpy roads or sharp turns, the spring shock absorber can greatly improve the stability of the car, effectively protect the shock-absorbing suspension system, and at the same time extend its service life . Damaged shock spring seals reduce shock replacement costs and save money.
