Precision upgrade for Yokomo on-road diffs

The Yokomo BD-500GA Aluminum Gear Diff Shaft is a targeted upgrade for racers and hobbyists running BD7/5 and B-MAX2/4 cars. Its light construction lowers rotating mass to help throttle response, and the hard alumite finish gives dependable wear resistance for frequent track sessions.

Features and fitment details

  • Material: Aluminum to cut weight and improve dynamic response
  • Treatment: Hard alumite surface for long service life under load
  • Compatibility: Fits a range of chassis including DP-YD2, B-MAX2MR, B-YZ2, and MRTC-BD7 series
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.

Will this improve acceleration on a tuned BD7?

Yes. Reducing the diff shaft mass helps the drivetrain respond faster to throttle inputs, which is beneficial on tuned BD7 setups where quick spool and control matter.

Is installation difficult for a club racer?

Installation is straightforward for anyone familiar with diff servicing. It replaces the stock shaft without special tools beyond basic diff assembly tools and a clean workspace.

Do I need different diff oil after fitting this shaft?

Not necessarily. You can use your existing oil grades; choose your viscosity to tune lock and throttle feel as usual. The shaft itself does not dictate oil weight.
