This 44mm L.F. Universal Bone from Yokomo is an RC-scale replacement drive link machined from aluminum to reduce rotational friction in universal shaft assemblies.
Compatibility is limited to the platforms explicitly listed by the source, namely SD-LCG and Drift Master; do not assume fitment on other layouts without verification.
Installation is intended as a like-for-like swap where a 44mm universal bone is required; check end fittings and retaining hardware on your model before assembly. Use standard workshop practice to confirm correct alignment and secure retaining pins or screws.
In tuning terms the part serves to reduce driveline drag at the universal joint, which can smooth input on low-speed throttle transitions and refine handling balance for drift setups where minimal resistance through the driveline is desired.
