RK-351-12415-L80
Yoke Shaft Cam Kit, Air Release
SAF-Holland

Engineered for high‑cycle duty in heavy‑duty fleets, this air‑release variant integrates a calibrated pneumatic assist into the release pathway, enabling rapid, consistent coupling and uncoupling with less manual effort. The core yoke, shaft, and cam components preserve dimensional accuracy to maintain smooth motion and precise jaw alignment, even after thousands of cycles under load. The air assist complements the mechanical locking action by reducing operator fatigue and improving responsiveness in cold starts or adverse weather. The assembly remains compatible with the XA‑351/‑331 family of fifth‑wheel couplings and is suitable for factory service or field rebuilds during routine maintenance. Typical service components such as the release lever, pivot hardware, springs, and fasteners are supplied as needed, helping to avoid part mismatches. Category: 42521; VMRS: 059‑001‑032.
