Yokomo's S4-010C93A is a 93mm centre dog bone crafted to suit the YZ-4S centre differential, helping to stabilise the drivetrain and reduce unwanted movement. It is a direct-fit component intended to match the YZ-4S geometry.
The 93mm dimension is chosen to align with YZ-4S centre differential spacing, offering steadier torque transmission and lower lateral slop. Precision finishing helps protect mating parts from premature wear.
Compatible with the YZ-4S platform, including the B-YZ4SF variant, this centre drive shaft installs with minimal fuss and is suitable for regular maintenance swaps or upgrades during set-up changes.
