Fifth Wheel - Hld Int, FW31, 6.625 in, Left Hand, No Lubrication
SAF-Holland

This left‑hand, no‑lubrication variant delivers the same core towing interface benefits with a focus on reduced maintenance intervals. The kingpin mounting height of 7 in and a 2 in kingpin diameter are incorporated into a stationary bracket design built for reliability in daily driver and fleet service. Maximum capacity remains 150,000 lbs, providing ample strength for standard heavy‑duty operations while minimizing wear through a proven keep‑clear, low‑friction release path on the LH lever. The FW31 model alignment ensures compatibility with widely used trailer configurations, enabling straightforward field retrofits or new builds without bespoke hardware. VMRS 059-001-135 anchors the unit to common maintenance workflows, and there are no cross references listed for this variant, signaling a dedicated, no‑lubricant solution that emphasizes simplicity and longevity. Category context places this component in the trailer coupling family, where predictable engagement and breakaway resistance are vital for safe, efficient operation in busy hubs and on congested highways.
