Rebuild Kit Left-Hand Release
SAF-Holland

Designed to restore precise, reliable disengagement on standard fifth wheel couplings, this rebuild kit targets the left-side release lever and associated hardware. Over time high-cycle operation and exposure to dirt, moisture, and vibration can cause play, stiffness, or inconsistent jaw opening, which compromises safety and increases coupling time. By replacing worn release components with a coordinated set, operators regain smooth actuation, predictable throw, and correct lever-to-linkage geometry across the full range of motion. The kit supports fleets using a LH release configuration and is compatible with typical fifth wheel assemblies found in both OEM and aftermarket rolls. The VMRS code 059-001-032 anchors the resource in the release mechanism family, while category context indicates a 42521 classification within fifth wheel components. Proper installation ensures the release operates without binding at the handle, maintains reliable relock after disengagement, and reduces the chance of late or incomplete uncoupling. As with any rebuild, follow the recommended lubrication points and torque values to ensure consistent operation under load, especially in remote or high-mileage environments.
