Precision O-Rings Tailored for Ultima RB7.5

For club racers and weekend tuners, the Kyosho W5312-03 Shock O-Ring Set keeps your suspension sealed and predictable. Designed to fit the Ultima RB7.5 series, these seals help prevent oil loss and support consistent shock response when you dial in your setup.

Material That Stands Up to Use

These O-rings are produced from robust compounds that maintain elasticity under repeated compression and exposure to shock fluids. That resilience helps minimise service frequency and keeps ride quality steady.

Plug-and-Play Compatibility

The set is matched to the shock geometry on the Ultima RB7.5, which means you can fit them quickly during routine rebuilds without hunting for alternative sizes or improvising seals.
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 use these O-rings with aftermarket shock cartridges?

They are intended for Ultima RB7.5 shocks. Aftermarket cartridges that share the same seal dimensions may accept them, but verify measurements before fitting to avoid leaks.

What signs indicate a worn O-ring?

Look for oil trails on the shock body, flattened or cracked seals, or inconsistent damping. Any of these signs point to a need for replacement.

Is there a recommended lubricant for installation?

A light smear of the same shock oil you run is ideal to help slide the O-ring into place and ensure proper seating without pinching the seal.
