  • Open radiator compartment for air flow
• Standard high-capacity alternator - 85 amps for maximum accessory capability

* The engine horsepower information is provided by the engine manufacturer to be used for comparison purposes only. The actual operating horsepower will be less.

XUV front suspension detail

To complement the most capable frame available in a high-performance utility vehicle, the XUV is equipped with four-wheel independent suspension.

A dual A-arm front and rear suspension provides a smooth ride over challenging terrain and excellent hauling characteristics.

The entire suspension system has been optimized to handle no cargo to maximum cargo without compromising ride quality or vehicle stability.

Dual A-arm front suspension features include:

• 201 mm (7.9 in.) of travel provides ample compression and wheel extension, which keep all four wheels on the ground for superior traction and vehicle control
• 17.5-mm (0.6875-in.) solid anti-roll bar with fully rubber isolated connecting links and pivots for minimal vehicle body roll and quiet operation
• Heavy-duty, nodular cast-iron knuckles to support the strut, constant-velocity (CV) shaft, and wheel
• Maintenance-free rubber torsional A-arm pivots for long life and quiet operation
• CV shaft protection from sticks that may puncture the rubber boot

XUV rear suspension detail

Dual A-arm independent rear suspension features include:

• Unequal length, dual A-arm construction for superior wheel control and travel
• 231 mm (9.1 in.) of total travel provides ample compression and wheel extension, which keep all four wheels on the ground for superior traction, excellent ride quality, and vehicle control
• Coil-over shocks absorb the most demanding terrain
• A-arms made from square/rectangular tubing reduce weight while remaining rigid
• Heavy-duty, nodular cast-iron uprights support wheel loads with a double row of ball bearings
• CV driveshaft protection from sticks that may puncture the rubber boot
• Rear sway bar for lateral stability

Deluxe cargo box

The deluxe cargo box consists of a 15 percent glass-filled polypropylene composite material that eliminates rust, dents, and reduces noise.

Deluxe cargo box tailgate

Tailgate handle

Tailgate lowered to 150 degrees

The tailgate can be opened or removed for easier cleanout and to carry longer items. The tailgate has been improved, features truck-like performance, and can be operated with one hand.

The standard installed lanyards can also be removed to lower the tailgate to 150 degrees for convenient loading and unloading tasks.

Deluxe cargo box tilt

Integrated handle for manual cargo-box tilt

The deluxe cargo box is easier to latch, unlatch, raise, and lower with the integrated handle design and gas assist.

A prop rod is provided to hold the box in the upright position for operator convenience, as well as limit box pivot travel.

Integrated tie-down points

Additional tie-down points (TH 6X4 shown)

The deluxe cargo box offers integrated tie-down points for increased versatility. Tie down points are located in the following areas:

• Four corners inside the cargo-box bed
• Four points on the load guard directly behind the operator station (A)
• Tie-down bars on either side of the cargo box (B)
• Six points on the underside of the cargo-box frame (circled)

Converting deluxe cargo box to a flat bed

The deluxe cargo box easily converts to a flat bed. The flatbed configuration allows loading larger cargo.

Optional accessories

Brake and taillight with optional protector

Bedmat protects the steel floor from dents

Cargo box power lift

Optional accessories for the deluxe cargo box include:

• Factory-installed brake and taillight
• Factory-installed spray-in liner (not shown)
  • Improves skid resistance and surface abrasion protection
• Cargo box bed mat
• Cargo box power lift

Specifications

CAUTION: Carrying extra-long cargo that extends beyond the box can adversely affect stability.

This Gator© XUV Crossover Utility Vehicle is equipped with power steering and a dual A-arm front suspension. These automotive-type systems exhibit excellent handling characteristics, as well as responsive steering and low steering effort:

• Steel ball bearings secure the steering shaft and deliver smooth, responsive operation
• Completely sealed rack-and-pinion for long life
• Low steering ratio (lock-to-lock) provides more responsive steering and less operator input
• Shaft U-joints are phased for a smooth, uninterrupted motion of the steering wheel
• Tilt steering wheel with 15 degrees of travel (XUV835M, XUV835R, XUV865M, and XUV865R models only; S4 models do not have tilt steering)

Electric power-assist steering system

Electric power-assist steering (EPAS) system has advanced features:

• Anti-kickback feature reduces the amount of steering unwinding when traversing difficult terrain.
• The system is speed sensing and adjusts steering effort as the speed of the vehicle changes.
  • As speed increases, there is less steering assist for improved road feel.
  • As speed decreases, steering assist increases to give lower steering efforts for improved maneuverability.
• A warning/functional light on the instrument panel provides self-diagnostics and a warning light in the situation of no assist.
• Torque sensor measures steering wheel input so the on-board computer can provide the appropriate output for various driving situations.

With the EPAS system, the operator maintains a direct, mechanical linkage from the steering wheel to the front wheels. The power-steering system interfaces mechanically with the steering system by being inserted between the steering wheel and the rack-and-pinion assembly.

A differential torque sensor is integrated into the power steering assembly. The circuit board assembly is also integral with the power-steering assembly.

Power steering does not reduce turning radius but significantly reduces steering effort by approximately 85 percent compared to those models without power steering.
