Special Features | Easy to Install, The plastic part is made of a stronger and more durable plastic material, which is more resistant to wear and tear and less likely to crack. The rubber material in the circular holes is more firmly bonded to the plastic and is less likely to separate due to frictional displacement during shock absorption. The metal part is stainless steel, which is not affected by water vapour and rusts and becomes brittle and breaks, making the shock absorber last longer., The shock absorber is able to extend and contract more smoothly, resulting in good damping. |
