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.
