SPRINGFIELD, Mo. – Ridewell Suspensions has expanded its air ride suspension line with the release of the RAR-251 Stub Axle Air Ride Suspension for heavy haul applications.
“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 Suspensions. “In addition, the air ride suspension offers a better ride quality for trailer owners seeking an alternative to mechanical trunnion suspensions.”
The new suspension system contains two beam assemblies that can be integrated with a 32” track Ridewell axle configuration with Wabco PAN 19 disc brake assemblies.
The initial release of the RAR-251 is designed for a minimum 10-foot wide trailer and up to a 14-foot or wider trailer installation. It accommodates 225-70R 19.5 and 245-70R 19.5 tire sizes at a 12” ride height.
Additional configurations include a 12.25” drum brake assembly for 17.5” tires and a Ridewell stub axle with a PAN 19 disc brakes configuration to accommodate a 22.5” wheel.
