An off-highway recreational vehicle having a longitudinal centerline includes a frame and a rear suspension. The rear suspension includes a left A-arm, wherein the left A-arm has a pivot axis, the pivot axis being on a right-hand side of the longitudinal centerline.

A UTV portal axle system is disclosed, including a spindle with a housing for housing input and output drive gears coupled by one or more idler gears. The output drive gear is disposed lower than the input drive gear to provide additional ground clearance to the UTV. The king pin axis angle is substantially the same as that of a stock UTV, while maintaining a scrub radius of substantially one inch or less. This is accomplished by the lower control arm ball joint being located within a recess of the output drive gear. This allows the UTV to be properly controlled when driven at high speeds over rough or uneven terrain. The gears may be interchangeable to allow the gear ratio to be adjusted to be more suitable for use at various driving speeds. A method of changing the gear ratio is also disclosed.

A utility vehicle includes a rear suspension assembly which has a trailing arm generally extending longitudinally. Also, the rear suspension assembly includes an upper radius rod extending in a generally lateral direction relative to a centerline of the vehicle. Additionally, the rear suspension assembly includes a lower radius rod extending in a generally lateral direction relative to the centerline of the vehicle. The rear suspension assembly further includes a suspension member configured to control toe of the at least one rear ground-engaging member.

Embodiments relate to an off-road vehicle comprising a frame, including at least one cargo box support member, a suspension movably coupled to the frame, a passenger compartment, an engine, a transmission operatively coupled to the engine, and a cargo box. The cargo box includes a floor and a plurality of upwardly extending sidewalls, wherein at least a portion of the cargo box floor extends over the at least one cargo box support member and wherein the cargo box is removably coupled to the at least one cargo box support members and is removable from the off-road vehicle via the removal of fewer than eight fasteners.

A suspension element includes a housing, a first joint, and a second joint. The housing is configured to couple a tractive element assembly to a vehicle. The housing has a first end configured to engage a portion of the vehicle and a second end configured to interface with the tractive element assembly. The first joint includes a first actuator and a first resilient member. The first actuator is configured to facilitate linear extension and retraction of the suspension element. The second joint includes a second actuator and a second resilient member. The second actuator is configured to facilitate rotational movement of the suspension element. The first resilient member and the second resilient member are configured to support a static load of the vehicle.

A utility vehicle with ergonomic, safety, and maintenance features is disclosed. A vehicle is also disclosed with improved cooling, suspension and drive systems. These features enhance the utility of the vehicle.

A suspension device and an all-terrain vehicle are provided. The suspension device includes: a first rocker arm having a first end provided with a first position limiting portion; a second rocker arm spaced apart from the first rocker arm; and a steering knuckle arranged between the first end of the first rocker arm and the second rocker arm. The steering knuckle is connected with the first end of the first rocker arm and a first end of the second rocker arm, and the steering knuckle includes a third position limiting portion configured to be fitted with the first position limiting portion. The third position limiting portion is configured to abut against the first position limiting portion when the steering knuckle is moved to a first extreme height position and the all-terrain vehicle has a first maximum steering angle.

A utility vehicle includes a plurality of ground-engaging members, a frame, a powertrain assembly, a front suspension assembly, and a rear suspension assembly. A cargo bed may be supported by the frame at the rear of the vehicle. The vehicle also includes an operator seat and at least one passenger seat positioned within an operator area. In one embodiment, the vehicle includes doors to enclose the operator area.

An off-road vehicle includes a frame, an engine, a rear ground engaging member, and a first rear trailing arm and a second rear trailing arm. Each of the trailing arms have at least one housing and wherein, within each housing is a drive belt, the drive belt drivingly coupled to the engine and a rear ground engaging member.

A bump stop assembly for a UTV with a frame attachment, a shock absorber attachment, two panels, a shock absorber and a bracket. The frame attachment is coupled to the frame of the UTV and the shock absorber attachment is coupled to the shock absorber. The two panels extend between the frame attachment and the shock attachment. The bracket is coupled to the trailing arm of the suspension system of the UTV. The bump plate bracket has a bump plate located to contact the shock absorber when a force applied to the suspension system causes the suspension system to reach a predetermined level of a capacity of the suspension system to absorb. The bump plate transfers a portion of the force applied to the shock absorber. The shock absorber is configured to absorb energy transferred to the bump stop assembly by the force applied to the suspension system.
