Rebuild Kit
SAF-Holland

Strategically packaged to restore the original performance of a heavy-duty coupler assembly found in commercial trailers, this rebuild kit provides the essential gaskets, seals, springs, and mounting hardware required to refresh worn components and bring the unit back to factory-derived tolerances. By refreshing sealing surfaces and restoring proper preload, it helps minimize fluid leaks, reduce friction wear, and extend the interval between full replacements. Technicians benefit from a cost-effective, drop-in solution that aligns with OEM specifications, enabling accurate reassembly and consistent clamping force, engagement reliability, and predictable cycling under normal operating loads. The included components are selected for compatibility with the VMRS-coded maintenance class and are designed to withstand the demanding environments encountered in long-haul and regional fleets. Category context indicates maintenance applications for heavy-truck trailer couplings and related subsystems, making this kit suitable for mixed fleets that rely on standard rebuilds to maintain uptime. Cross references are not provided in the current dataset, but compatibility is typically verified via bore diameters, mounting hole patterns, and seal fits. In practice, applying this kit supports safer operations, minimizes downtime, and helps maintenance programs sustain high readiness without costly replacements.
