Keep Your Gear Diff Tight with Yokomo BD-500GOA

The Yokomo BD-500GOA Silicone O-Ring Set is a straightforward upgrade to maintain clean, predictable differential behaviour. Tailored for BD7 and BD5 series cars, these silicone rings help prevent oil escape and reduce the need for frequent top-ups.

Why Silicone Works Well

Silicone maintains elasticity across a wide temperature range, so the seals stay effective during long runs. The set includes four O-rings, enough for a full service and a spare for damage or trials.

Cross-Chassis Compatibility

These O-rings fit many common chassis types used in club and competitive racing. They are compatible with DP-DIB series and MRTC-BD10 setups, making them a handy part to keep in your spares box.
Remark :
Due to limited stock availability, please notice that some Yokomo 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.

What advantage does the BD-500GOA offer over stock seals?

Compared with older or worn seals, fresh silicone O-rings restore a positive seal that reduces oil loss and helps the differential hold its trim for more consistent lap times.

Can I use the same rings for different cars?

Yes, the BD-500GOA is made to suit a variety of chassis. Confirm compatibility with your specific model list; BD7 and BD5 are covered as standard.

Any tips for fitting the O-rings?

Clean the groove, apply a light film of diff oil to help seating, and avoid stretching the ring excessively when installing to prevent nicks or cuts.

Do these rings affect diff tuning?

The rings themselves do not change internal gearing, but by preventing leaks they help maintain the chosen oil viscosity and tune settings more reliably.
