Kingpin Assembly
SAF-Holland

This rear-axle kingpin assembly provides the critical pivot point for rear suspension and axle articulation in heavy-duty traction and trailer configurations. With a design oriented toward high-load environments, it ensures reliable engagement and rotation at the axle interface, supporting predictable wheel alignment and steering geometry. The assembly is optimized for durable service life under rugged road conditions, maintaining consistent contact surfaces and minimizing play that could compromise handling characteristics. By replacing worn kingpins on the rear end, fleets reduce the risk of uneven tire wear, misalignment-related stress, and potential tire or suspension damage. VMRS code 012-001-021 places the part within the kingpin assembly family, while category_id 42507 indicates its association with heavy-duty component groups involved in axle and steering linkages. This part is essential in maintaining safe, responsive trailer operation across varied load profiles and driving conditions.
