The UF-SS13 axle has been designed to be more compact and have improved ride performance.
The UF-SS13 has an 18.85-inch package size and is designed up to four inches shorter than our comparable lift axles. Its compact design allows it to fit into tighter spaces creating more frame rail space for tanks and other components, minimizes axle spacing for multi-axle configuration. The UF-SS13’s compact design on a new truck can reduce the vehicle’s overall wheelbase as well.
