RK-351-12415-L-80
Left-Hand Yoke, Yoke Shaft, Cam Kit XA-351/-331 Series
SAF-Holland

Within the XA‑351/‑331 family, this Left‑Hand rebuild package corresponds to the 80 variant and bundles the essential components needed to restore the original release and engagement performance. It covers the critical interfaces between the release‑lever axis, cam eccentric, and yoke geometry, ensuring consistent locking torque and reliable uncoupling after wear or impact. The updated hardware is designed to withstand high cycle counts and harsh environmental conditions typical of on‑highway service. When installed during planned wheel‑end service, technicians benefit from a straightforward retrofit that minimizes guesswork and eliminates missing parts. Proper reassembly yields smooth release action, precise jaw alignment, and predictable clamping force on the kingpin, enabling safer, more confident coupling in variable load scenarios. This package resides in the Fifth Wheel family and is identified by the VMRS group for kit rebuilds, 059‑001‑030. Cross references: none listed.
