Yokomo R12-20S Rear Bulk Head Shaft for R12  [R12-20S]

Rear bulkhead shaft for R12 and GT series

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.
