Air Spring
SAF-Holland

The 64637-SAF air spring is a critical component of heavy-duty suspension systems, delivering improved ride quality and consistent load support for all-weather operation. Through a rugged, reinforced bellows and precisely engineered end fittings, this part translates varying road conditions into controlled vertical movement, helping to maintain axle height and tire contact. By automatically adjusting to load changes, it dampens bottom-out impacts and reduces chassis stress, which translates to longer tire life and more predictable handling on demanding road surfaces. Installation is streamlined for SAF-Holland compatible systems, with standardized mounting points and quick-connect fittings that minimize downtime during replacement. The design emphasizes resistance to air leakage and external contaminants, helping preserve performance in harsh environments. This means fewer maintenance cycles and a lower total cost of ownership for fleets that operate at high mileage and varying payloads. When you need reliable suspension performance and consistent ride dynamics, this air spring provides a dependable solution for heavy-duty trucks. Source One Parts Center.
