Trailer Suspension Alignment Block Assembly
SAF-Holland

This Trailer Suspension Alignment Block Assembly is a precision alignment component used to set and maintain proper axle position relative to the trailer frame and suspension geometry. Correct alignment is critical for uniform tire wear, optimal steering response, and predictable load distribution across the axle set. The assembly is designed to withstand the dynamic loads of highway operation, maintaining alignment through repetitive cycles and pothole encounters. VMRS code 016-008-085 places it within the alignment and spacing subgroup of trailer suspension components, while cross references to SGO 905 08 019 indicate compatibility with related alignment tooling and specifications. Category 42624 situates it within the trailer axle and suspension alignment category, underscoring its role in achieving and preserving correct geometry. Applications include maintenance, retrofit, and heavy haul operations where precise alignment directly influences safety and operational efficiency. The listing notes a standard P65 warning on the safety label. In service, the alignment block assembly helps reduce uneven tire wear, lowers steering strain, and contributes to longer service life for tires and suspension components by maintaining accurate geometry under load.
