A vehicle comprises a chassis, a seat, an endless drive track, a rear suspension assembly with at least one slide rail and a substantially inextensible limiter strap extending between the chassis and the at least one slide rail, to limit separation between the at least one slide rail and the chassis. The strap holder is moveable between a first holder position and a second holder position, a position of the end of the limiter strap being different in the first strap holder position compared to the second strap holder position. A control cable is operatively connects the strap holder to a strap adjustment actuator. The strap adjustment actuator is disposed forward of the seat and is operable by a user during operation of the vehicle, the strap adjustment actuator being movable between first and second positions related to the positions of the strap holder.

A suspension travel control system for a vehicle suspension is disclosed. The suspension travel control system includes a stop post secured to the vehicle frame and a suspension travel control formation that includes a base and a body. The stop post is positioned in a space defined by the body. The suspension travel control formation may be secured to the axle, the main support member or incorporated into the axle coupling assembly to provide a rebound and jounce stop as well as longitudinal redundancy in the event of the failure or loss of a longitudinal linkage.

A two-piece limit strap clamp for use with a shock absorber and a limit strap retention device is provided. The pieces couple together around the upper end of a shock absorber. The clamp has a protrusion that extends outwardly and is adapted for attachment of the top end of a limit strap. The lower end of the limit strap may be attached to a mounting tab that is coupled to the lower mounting bracket of the shock absorber. Also disclosed is a limit strap with a tether coupled to a spring of the shock absorber to prevent the limit strap from bowing out when the shock absorber is compressed. A method of use of a limit strap with a tether is also disclosed.

A mechanical down-stop for heavy-duty vehicle axle/suspension systems which includes an angled bracket that is rigidly/stiffly attached to the vehicle frame at one end, and is attached to a flexible portion of the mechanical down-stop at its other end. The flexible portion is attached to a beam of the axle/suspension system. The angled bracket is formed of an elastically deformable material and includes a bend that enables the bracket to act as a spring. The angled bracket and the flexible portion limit downward movement and react the downward force of the beam.

An air ride suspension assembly or kit is provided for converting a leaf spring suspension arrangement on a motor vehicle having a solid rear axle to one supported by an air ride suspension assembly is disclosed in order to leverage the benefits of such air ride suspension systems to the conversion suspension assembly is disclosed. A leaf spring is removed and replaced with an upper support arm which is secured to the pre-existing leaf spring attachment sites on the chassis. A mount is then attached to the rear solid axle to which multiple connections are made from the upper support arm including an air bladder. The air ride conversion system can be supplied as a kit for installation by owners of vehicles where they routinely move heavy loads directly with the vehicle or by towing.
