[Compatible] The shock absorber pad has an open circular appearance, with grooves on the upper and lower sides (used to accommodate coil springs) and nine oval-shaped shock absorber holes inside. [Durable and environmentally friendly] The buffer rubber is made of high-quality rubber and has the characteristics of wear resistance and toughness. Our inner knots are smooth and flat for a more refined appearance. The inner and outer edges of the cutting surface are high or low, with the outer edge being high and the inner edge being low, making installation more convenient. Bubble shock absorption: The buffer rubber has a hole specially designed for the oval buffer. A new type of cushioning product designed based on the principle of neutral dispersion of impact forces can greatly reduce impact forces in all directions. The shock absorption performance is greatly improved, limiting the vibration of the road surface during driving and reducing the vibration of the car. Stability: When using unpaved roads, bumpy roads or sharp turns, spring shock absorbers can greatly improve the stability of the car, effectively protect the shock absorber suspension system and extend its service life. The damage caused by the shock absorber spring joints reduces the cost of replacing shock absorbers and saves money. size: Spring clearance: 15mm Spring thickness: 9mm Spring diameter: 112mm Note: The data are all measured manually, please allow 1-3cm error Due to differences in light and display, there may be some color differences, please refer to the actual item received.
