Overview: rear bulk head shaft for R12 and GT models

This part is an RC-scale rear bulk head shaft engineered for the Yokomo R12 platform, provided as a replacement or an upgrade for the rear bulkhead assembly. It helps maintain correct rear axle geometry under load and preserves alignment when you are swapping components or optimising rear suspension for different surfaces.

Fitting is simple for hobbyists familiar with chassis teardown: remove the rear bulkhead, insert the replacement shaft into the bulkhead housing, then verify clearance with suspension links and driveshafts. Ensure the shaft seats properly and rotates smoothly before finishing the rebuild to prevent binding.

Tuning note: the shaft contributes to rear suspension geometry and squat characteristics; changing to a harder or differently finished shaft will alter rear behaviour under acceleration. Apply single-step changes and run controlled tests to measure handling differences.

Remark :

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.

How robust is the hardened steel shaft?

The shaft is made from hardened steel to resist wear and maintain alignment under load. Regular inspection for wear and correct lubrication of mating surfaces will prolong service life.

Is this suitable for carpet racing setups?

Yes. The shaft is useful on carpet and asphalt alike since it stabilises rear axle geometry; final suspension tuning should still be adjusted for the specific track surface.

Any setup advice when swapping shafts?

Change only one variable at a time and record lap data. Small differences in shaft stiffness or finish can noticeably affect traction and corner exit, so systematic testing yields the best results.
