Product information "S-TECH Factory aluminum separating piston WP XACT5448"
S-TECH SEPARATING PISTON FOR WP DAMPERS ;
DESIGN: STANDARD VOLUME
To separate oil and nitrogen in the shock absorber, WP uses a plastic separating piston in its shock absorbers
.
The original part from WP only uses an O-ring for sealing. This can cause the separating piston to tilt in the housing and consequently break. This can also increase the friction coefficients, which can lead to greater heat build-up and poorer response behavior
The separating piston can be installed without significant effort during a service or tuning
