Abstract: A suspension kit is provided for use in heavy duty vehicles having an independent front suspension including air springs, the kit includes an anti-roll bar having two ends, each end configured for connection to the front suspension in operational relationship to an associated one of two front wheel assemblies, at least one ping tank in fluid communication with an associated one of the air springs, a valve in fluid communication between each at least one ping tank and the associated air spring, a control switch connected to each valve for moving the valve between an open position, allowing fluid communication between the at least one ping tank and the air spring, and a closed position, closing fluid communication between the at least one ping tank and the air spring. An associated front suspension is also provided.

Abstract: A modular axle clamp and riser system for use in a suspension system, which includes a top mount having a substantially flat upper surface, a top mount body which extends transversely to the flat upper surface, a pair of opposing ears which extend from the top mount body, and at least one top mount tooth extending from the top mount body in a direction opposite the ears. Also included is a wedge with at least one wedge tooth which matingly engages the at least one top mount tooth, a wedge upper surface, and a pinion angle surface. Further, the wedge defines a pinion angle between the wedge upper surface and the pinion angle surface. Moreover, an axle mount with at least one axle mount tooth which matingly engages at least one of the at least one top mount tooth and the at least one wedge tooth is provided.
