Technical O-Rings for Sakura M4 Pro Shock Assemblies

The 3Racing Sakura M4 P3 O-Ring set is engineered to meet the dimensional tolerances required by Sakura M4 Pro shock components. Measuring 2.9 x 1.9mm, these rings maintain seal integrity to preserve damping repeatability across rebuilds.

Precision Construction and Race Focus

Fabricated from a durable elastomer selected for consistent compression set and compatibility with silicone shock oils, these O-Rings offer steady performance under the thermal and mechanical stresses common in race use. They install without modification into Sakura M4 Pro hardware.

Technical Notes

  • Specifically sized for Sakura M4 Pro shock systems
  • Material chosen for low compression set and oil resistance
  • Accurate dimensions: 2.9 x 1.9mm for repeatable sealing
  • Includes 5 pieces to support multiple rebuilds

What material properties are important for shock O-Rings?

Low compression set, good oil compatibility and dimensional stability under heat are key. These rings are selected to balance those properties for repeatable damping.

How should I inspect O-Rings during a rebuild?

Look for nicks, flat spots, or hardening. Replace rings showing any deterioration to avoid changes in shock behaviour.

Are these O-Rings suitable for frequent rebuilds at events?

Yes, the five-piece pack supports multiple rebuilds and is useful for quick service between qualifying runs or heats.
