MX-TECH Low-Friction Shock Piston Ring Kit SHOWA 40 mm for HONDA CR 85, CRF 150 and SUZUKI RM 85 2003-2026

The MX-TECH SHOWA 40 mm PB01SHPB-0002 shock piston ring kit is designed for HONDA CR 85, CRF 150 and SUZUKI RM 85 from 2003 to 2026. The shock piston ring (piston band) seals between the piston and the body: the oil has to pass through the valves, not around the piston. This kit replaces the original ring with a low-friction ring fitted over an O-ring.

Specifications

• Brand: MX-TECH
• Manufacturer part number: PB01SHPB-0002
• EAN code: 01000220
• O-ring included

When to replace it?

• Piston ring worn or scored at service.
• Damping that fades as the shock heats up.
• Shock service or tuning.

Check the make and the piston diameter of your shock (in the name). This job is done with the shock taken apart and drained of nitrogen: it is meant for workshops and properly equipped mechanics.

Fitting tips

1. Release the nitrogen and take the shock apart following the manual.
2. Remove the old ring from the piston without scratching the groove.
3. Fit the O-ring and then the ring, refit the piston and bleed the shock before recharging the nitrogen.
