Race-Grade Aluminium Rear Universal Shaft

Targeted at Yokomo BD cars, the B9-010RAA rear universal drive shaft combines reduced weight with solid construction to help drivers get crisper feedback. The aluminium build is chosen to balance longevity with improved driveline dynamics.

Chassis Compatibility and Features

The shaft is suitable for numerous Yokomo BD chassis variants including MRTC-BD919, MRTC-BD10 and MSR-BD11 lines. Its 44.5mm aluminium bone construction reduces inertia while maintaining the stiffness needed for consistent lap-to-lap performance.

Main Advantages

  • Lower Rotating Weight: Aluminium bone design cuts mass where it matters for quicker response.
  • Consistent Handling: Helps deliver predictable steering and traction transitions.
  • Wide Compatibility: Designed to fit many BD series models without extensive modification.

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.

Do I need to change other parts when fitting this shaft?

In many cases no other parts are required, but inspect dogbones, cups and diff interfaces for wear and replace as necessary for a reliable install.

How does aluminium compare to steel for drive shafts?

Aluminium offers lower weight and good stiffness but less impact resistance than steel; choose based on whether reduced mass or maximum toughness is the priority.

What checks should I do after a crash?

After an impact, check the shaft for bends, inspect set screws and mating cups, and ensure the diff and hubs are undamaged before running again.

Is the B9-010RAA a direct bolt-in for BD11?

It is designed to fit BD11 variants listed in the compatibility section, but confirm fit with your specific submodel and hardware as chassis revisions can vary.
