The cargo box consists of a high-density polyethylene copolymer composite material that eliminates rust, dents, and reduces noise. This large, one-piece design has rounded inside corners to ensure material removal when tilted. The composite box is highly ribbed and supported with a welded steel-ladder structure to ensure hard-driving performance and longevity. The three highly styled exterior pieces are made of thermoplastic polyolefin (TPO) for extra durability.

Cargo box tailgate

The tailgate can be opened or removed for easier cleanout and to carry longer items. It features truck-like performance and can be operated with one hand.
 
The tailgate’s pivot point is made of hardened steel for durability and designed for tool-less removal.  The standard lanyards can also be disconnected without tools to remove the tailgate for convenient loading and unloading tasks.

Cargo box tilt and removal

The cargo box ease of use is critical to performing tasks quickly and efficiently. Starting with the truck-style tailgate, the removal of content in this cargo box is much easier. The manual release functions as the lift lever as well, done in a smooth, one step motion. It can even be tilted from both sides of the vehicle. To reduce the overall effort of lift, the pivot point of the cargo box is closer to the center. The combination of easy-to-use attributes makes this cargo box best in class.

 

With the removal of two bolts, the cargo box can easily be detached from the vehicle frame for ease of servicing.

Integrated tie-down points

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

•  Flip-up D-shaped rings in all four corners inside the cargo-box bed
•  Multiple points along the edge of the cargo box side walls
•  Tie-down bars on either side of the cargo box with optional cargo box rail kit. This kit also provides a mounting system using accessories that possess the 25.4-mm (1-in.) quick clamp.

Optional accessories

Optional accessories for the cargo box include:

• Factory-installed cargo box rail system
• Cargo box bed mat
• Cargo box wall extensions

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

To complement the capable powertrain on the RSX860E and RSX860M, the RSX is equipped with four-wheel independent suspension. This unique suspension setup provides an unparalleled ride over challenging terrain and excellent handling through corners.

 

The engineering team in collaboration with engineering firms that consult with Formula 1®, NASCAR®, and INDYCAR® teams, built a sport-tuned suspension system for class-leading operator comfort, no matter the terrain, and handling that makes one think they are on rails.

Dual A-arm front suspension features include:

• Dual, wide-arch A-arm design provides maximum front-wheel control, precise steering, and maximum ground clearance out to the wheel
• 23 cm (9 in.) of travel provides ample compression and wheel extension, which keep all four wheels on the ground for superior traction and vehicle control
• Exclusive aluminum-body, high-pressure monotube shocks or piggyback shocks, both provided by FOX Racing Shox® company (see more details below)
• Solid anti-roll bar, with fully rubber isolated connecting links and pivots, is tuned to provide the most agile and predictable handling
• Camber during compression to compensate for body roll and to maintain an optimal tire contact patch for improved cornering grip
• Increasing vehicle width during compression for additional stability.
• High-strength ASTM 80-55-06 ductile cast-iron knuckle and upper A-arm to support the high stresses of the shocks, constant-velocity (CV) shaft, and wheels
• Automotive-style fully boxed and welded-steel lower A-arms to minimize unsprung mass and maximize strength
• Maintenance-free rubber torsional A-arm pivots for long life and quiet operation
• CV shaft protection from sticks that may puncture the rubber boot
• Anti-dive front suspension geometry provides a solid platform for confident braking

Multi-link IRS rear suspension features include:

• Exclusive multi-link, semi-trailing arm rear suspension moves wheels rearward and outward in compression
• 23 cm (9 in.) (23 cm) of travel provides ample compression and wheel extension, which keep all four wheels on the ground for superior traction and vehicle control
• Exclusive aluminum-body, high-pressure monotube shocks or piggyback shocks; both provided by FOX Racing Shox (see more details below)
• Solid anti-roll bar, with fully rubber isolated connecting links and pivots, is tuned to provide the most agile and predictable handling
• Camber during compression to compensate for body roll and to maintain an optimal tire contact patch for improved cornering grip
• Increasing vehicle width during compression for additional stability.
• High-strength ASTM 80-55-06 ductile cast-iron knuckle and lower A-arm to support the high stresses of the shocks, CV shaft, and wheels with the toughness to survive impacts from boulders
• Heat-treated, aluminum-cast, upper A-arms to minimize unsprung mass
• Maintenance-free, rubber-torsional A-arm pivots for long life and quiet operation

Standard equipment shocks on the base model– front and rear suspension

• Exclusive aluminum-body, high-pressure monotube FOX racing shocks
  • Fully adjustable spring preload for different driving styles
  • High-pressure nitrogen gas is separated from the damping oil by an internal floating piston (IFP). The separation prevents aeration (frothing) and viscosity degradation of the oil which improves damping consistency and performance fade.
  • Pressure and heat generation in the monotube is less than a traditional twin-tube shock, allowing for better vehicle control in aggressive conditions.
  • The single aluminum shell of the monotube design allows for more efficient heat rejection and lower overall unsprung mass.
  • Mounting the shaft end of the shock to the suspension arm lowers the unsprung mass of the suspension system, leading to improved suspension response.
