Specifications

The TR9921 trailer air spring is a high-performance suspension component designed to support heavy loads and improve ride quality in trailer applications. Manufactured with reinforced rubber and precision-engineered components, it effectively absorbs shocks and vibrations while maintaining consistent ride height. This helps protect cargo and reduces stress on suspension systems, extending the life of surrounding components. Sold by Wofford Truck Parts, the TR9921 is ideal for fleet operators and independent haulers seeking durability, reliability, and optimal performance in a wide range of road conditions and load requirements.
