Rebuild Kit
SAF-Holland

Another rebuild kit option in the SAF-Holland line focuses on the primary release mechanism of the fifth-wheel assembly. This kit targets left-hand variants and includes components designed to restore precise actuation, smooth release, and reliable coupling across a wide range of trailer configurations. By replacing degraded springs, bushings, seals, and related hardware, technicians can reclaim original performance levels, minimize stickiness, and reduce abusive stress during pitch and retraction cycles. VMRS code 059-001-002 places it in the air-release and actuation family, reflecting its role in controlling the release function. Category context: 42517. The kit is suitable for service retrofits, prebuy inspections, and retrofit programs to keep older systems up to date. Cross references are not listed. Applications include fleets that require consistent release feel, predictable uncoupling across varied payloads, and improved safety margins during nighttime or high-stress operations. The rebuild approach emphasizes modular wear parts that simplify maintenance and lower total cost of ownership by extending service intervals and preserving component life under demanding conditions.
