Ridewell Suspensions has expanded its air ride suspension line with an integrated stub axle suspension system for heavy haul applications called the RAR-251.

The RAR-251 contains two beam assemblies that can be integrated with a 31-inch track Ridewell axle configured with Wabco PAN 19 disc brake assemblies.

“The unique pivot design and excellent lateral stiffness of the RAR-251 suspension provides a significant increase in capacity for trailer manufacturers wanting a multi-tire configuration that provides a 40,000-pound capacity per axle line,” said Bruce Barton, director of engineering at Ridewell. “In addition, the air ride suspension offers a better ride quality for trailer owners seeking an alternative to mechanical trunnion suspensions.”

The initial release of the RAR-251 system is designed for a minimum 10-foot wide trailer up to a 14-foot or wider trailer installation. The suspension can accommodate 225-70R 19.5 and 245-70R 19.5 tire sizes at a 12-inch ride height. Ridewell can provide a hanger specifically designed for the application or a customer can use their own.

Other configurations include a 12.25-inch drum brake assembly for 17.5-inch tires and a Ridewell stub axle with a PAN 19 disc brakes configuration to accommodate a 22.5-inch wheel.
