Precision Seals for Ultima RB7.5 Shock Units

To keep your car handling predictably lap after lap, fit the Kyosho W5312-03 Shock O-Ring Set on Ultima RB7.5 dampers. These seals reduce oil weep and help the shock maintain consistent damping characteristics between services.

Long Life Under Regular Service

The O-rings are produced from a material blend chosen for elasticity and resistance to oil exposure, which helps them survive repeated compression cycles and extend service intervals.

Accurate Dimensions for Hassle-Free Install

Matched to the original shock specifications for the Ultima RB7.5, this set makes replacement straightforward so you can restore factory sealing without trial and error.
Remark :
Due to limited stock availability, please notice that some Kyosho items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Can I replace just one damaged O-ring or replace the set?

You can replace only the damaged O-ring if needed, but replacing the set during a rebuild ensures uniform seal condition and avoids mixing old and new parts.

What maintenance steps protect the seals?

Keep the shock area clean, use the correct shock oil, and inspect seals for nicks or hardening during each service to prolong life and prevent leaks.

Will different shock oils affect O-ring performance?

Some oils and additives can swell or harden seals; stick to recommended shock oils and check seals after switching oil brands or viscosities.

Any fitting tricks to avoid leaks?

Lightly coat the O-ring with shock oil before fitting and seat it evenly without rolling. Inspect the cap and shaft for burrs that could cut the seal.
