Rear Shock Absorber Assembly
SAF-Holland

Rear shock absorber assembly plays a critical role in controlling vertical wheel movement and axle wrap on heavy-duty trucks. It dampens energy from road irregularities and loaded cargo, reducing height bounce and swaying, which improves ride quality, tire contact, and vehicle stability during cornering and braking. The rear damper complements the front dampers to provide balanced suspension behavior, particularly under dynamic loads, enabling more consistent axle geometry and extended component life. The VMRS code 016-006-001 designates a rear shock absorber assembly within the VMRS system, assisting parts identification, maintenance planning, and cross reference matching. The category 42677 places this part within the front rear suspension family, aligning with similar dampers used across the drive and trailer axles. While OEM variations exist, this component aims to offer robust sealing integrity, corrosion resistant finishes, and reliable performance across temperature ranges. Fleet operators benefit from improved ride quality on highways and job sites, reduced driver fatigue, and lower maintenance costs due to fewer shock related failures when this unit is paired with compatible leaf or coil springs.
