90550179
Crossmember, Rear
SAF-Holland

A rear structural member designed to anchor and align key suspension and drivetrain components in heavy-duty applications. It maintains chassis rigidity and controls rear-end geometry, supporting loads from payload shifts, braking forces, and road impact. With robust material sections and precise welds, it tolerates high stress concentrations while preserving mounting accuracy for trailing arms, differential housings, and shock/strut connections. The VMRS code 014-001-006 identifies its function within the rear crossmember family, ensuring compatibility with SAF-Holland rear suspension configurations and substitute assemblies. The cross-reference NEW 90550179 confirms suitability across a wide range of chassis configurations, simplifying parts replacement decisions. Category 42675 highlights its role in the rear subframe, enabling consistent torque transfer, stable tracking, and predictable tire wear. Field installation requires correct alignment, torqueing, and routing of nearby lines and cables. When correctly installed, the component helps deliver reliable ride satisfaction, improved stability on uneven surfaces, and extended service intervals for the overall suspension system.
