RK-NT-ILS-S
No-Tilt ILS Retrofit Slider
SAF-Holland

A no-tilt retrofit slider assembly designed to mate with standard SAF-Holland mounting patterns, this component enhances alignment during hitch coupling and minimizes tilt under load. By maintaining precise contact between the kingpin interface and the mating plate, it reduces side loads and wear on mating surfaces, contributing to smoother operation and longer service life in high-cycle cycles. The unit is cataloged under VMRS code 059-001-032, which aligns maintenance documentation and parts interchangeability with other no-tilt retrofit components. Cross references list the compatible alternative or upgrade path as HLD RKNTILSS, ensuring technicians can verify substitutions during overhauls. In practice, fleets experience improved locking engagement, consistent towing geometry, and reduced maintenance frequency for the fifth wheel interface. Compatibility spans mid to late model tractors that originally supported a tilt or tilt-prone arrangement, with installation designed for minimal downtime and straightforward verification of travel clearance and lubrication points. Category context for this part falls under heavy-duty fifth wheel systems, reinforcing its role in optimizing coupling reliability, load distribution, and safety during long-haul and regional operations.
