AXIAL RR10 Bomber Steel Adjustable Main Shaft with Alloy Body by GPM RR237SAN  [RR237SAN]

Adjustable main shafts for scale crawlers

The GPM RR237SAN shaft set is an RC-scale replacement designed for AXIAL RR10 Bomber platforms, combining aluminum and hardened steel components to balance weight and durability. The alloy shaft body is machined from aluminum 6061‑T6 while the cross head sections use hardened steel #45, keeping rotating mass lower without removing the steel strength where steering articulation and load are concentrated.

The universal swing shaft cross head improves achievable steering angles, allowing greater articulation during slow-speed crawling. A pin-lock arrangement secures the head to the shaft to reduce the risk of loosening under repeated articulating motion. White silicone o-rings are supplied to isolate the head from the shaft body and reduce direct metal contact.

Lengths are adjustable to match front and rear driveline requirements: front 116–126mm, rear 147–157mm, which helps fit common RR10 Bomber link geometries. This kit is presented as an RC accessory intended for chassis tuning and repair, not for full-scale vehicle use.

Use this set when replacing worn shafts or when adjusting link lengths for improved steering articulation on RR10 Bomber rigs; confirm fit before installation and retain original hardware for reference.
