Description:

High temperature resistance, two holes design D31 cars Shock Absorber Piston

We are a professional factory engaging in producing shock absorber pistons, with many years experiences in this line.

As we know, shock absorbers play a large part in the performance of the vehicle and are therefore

advised for a routine check up at regular intervals.

We can offer you the pistons with good quality and fit for the different road condition. We choose

advanced material and this provides long seal life, contributing to shock absorbers that can meet the

demands from car manufacturers of one hundred thousand kilometers before replacement.
