R12 & GT series rear bulkhead shaft overview

This is an RC-scale rear bulk head shaft designed for the Yokomo R12 platform, supplied as a direct replacement or upgrade part for the rear bulkhead assembly. The component focuses on stabilising rear axle geometry and maintaining alignment under load, making it useful when swapping parts or fine-tuning rear suspension response on carpet or asphalt tracks.

Installation is straightforward for those familiar with basic chassis disassembly: remove the rear bulkhead, replace the shaft in the bulkhead housing, and confirm clearance with the rear suspension linkages and drive components. Check for correct seating and smooth rotation before final reassembly to avoid binding.

Tuning role: this shaft affects rear suspension geometry and squat behaviour; swapping to a stiffer or differently finished shaft can change rear-end feel during acceleration and corner exit. Use incremental changes and test laps to evaluate effects rather than multiple simultaneous component swaps.

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.

Which chassis are compatible with this shaft?

Refer to the listed models above; this shaft is intended for the Yokomo R12 platform and the specified GT series chassis shown in the compatibility list.

Do I need special tools to fit the shaft?

No specialised equipment is required. Standard RC hand tools and a correct-size hex driver will allow safe removal and refit of the rear bulkhead shaft; work methodically and verify clearances as you reassemble.

What handling differences should I expect after fitting?

Expect subtle shifts in rear-end stiffness and alignment that influence traction and corner exit. Make one change at a time and use timed runs to judge whether the new shaft improves rear grip or stability for your surface.
