GMADE R1 ROCK BUGGY Steel Adjustable Main Shaft with Alloy Body by GPM GM237SAN  [GM237SAN]

Adjustable main shaft set for R1

This is an RC-scale adjustable main shaft assembly designed for the GMADE R1 ROCK BUGGY platform, delivered as a multi-piece kit for axle and steering linkage tuning. The component uses a steel shaft core with an alloy-bodied head to balance rigidity and serviceability during slow-speed rock crawling tasks.

Key mechanical features carried over from the source data include a universal swing-shaft cross-head to increase achievable steering and crawling angles, and a pinned shaft head to reduce the risk of the head coming loose during vertical movement. The set includes measured adjustable lengths and small protection rings intended to limit direct metal-to-body contact.

Use this part when you need to fine-tune wheelbase or steering geometry on trail setups, or when replacing worn cross shafts after hard crawling sessions. Routine inspection of the pin lock and silicone O-rings will help maintain alignment and prevent premature wear. Refer to manual GM54311 for factory adjustment ranges and assembly reference rather than using this text as an installation manual.

Aimed at trail and rock crawling setups, this shaft set provides adjustable lengths and locking features to support geometry tuning on the GMADE R1 ROCK BUGGY while keeping maintenance straightforward.
