XA-AL-A-L-P
Aluminum Fifth Wheel
SAF-Holland

This aluminum fifth wheel configuration delivers a high strength to weight ratio optimized for heavy-duty towing while reducing unsprung and overall vehicle mass. The design supports a load rating class of 55000 pounds, providing confidence for long-haul and heavy-duty applications where payloads approach the upper limits of standard equipment. Constructed from aluminum, it offers corrosion resistance, improved thermal performance, and potential reductions in fuel consumption stemming from lower vehicle mass. The VMRS code 059-001-001 establishes its place in a distinct family of fifth wheel components with a shared set of mounting interfaces, compatibility requirements, and service considerations. Cross references include JOS JSK37HSL, signaling compatibility with specific installation kits and related locking or latching mechanisms used across fleets. In practice, operators can expect robust coupling stability, reduced maintenance frequency due to lighter weight, and enhanced overall vehicle efficiency when deployed in appropriate applications. Category context underscores its role as a high-strength, low-weight upgrade option within the fifth wheel platform family.
