90550138
Crossmember Assembly - Rear
SAF-Holland

Rear-end structural support used in heavy-duty chassis applications provides essential mounting points for trailing arms, springs, and attachment hardware that define rear suspension geometry. By maintaining lateral and longitudinal alignment under varying loads, it helps preserve wheel alignment, tire wear, and overall ride quality. The VMRS code 014-001-006 groups this part with other rear suspension crossmembers, facilitating correct interchange and compatibility with SAF-Holland rear modules and common OE patterns. The cross-reference NEW 90550138 identifies the appropriate family for replacement on a broad spectrum of long-haul and vocational vehicles, aiding technicians during maintenance planning. Category 42675 situates this component within the rear subframe ecosystem, reinforcing structural rigidity and load transfer between the frame rails and axle assemblies. Proper installation with the correct fasteners, bushings, and seal interfaces minimizes noise and micro-movement while maximizing durability. In fleet service, this part supports stable vehicle stance under heavy payloads, improves braking stability during deceleration, and contributes to consistent handling across road irregularities and temperature variations.
