Bigger. Better. Faster. Stronger.
Those are the words that come to mind when you climb behind the wheel of an RHA-450. The SportChassis RHA-450 is equipped with the largest available engine in its class -- the Detroit Diesel DD13 meaning more power and torque when you need it. The DD13 exerts 450 hp and a whopping 1.650 ft/lbs of torque across 1,100 to 1,600 RPM. The robust construction gives the DD13 a B50 service life of one million miles. For trailer loads that weigh in the 30K -40K pound range, the 112 chassis is your best bet to pull and stop the load safely.
Please note: Due to the Gross Vehicle Weight Rating (GVWR), a Commercial Driver's License (CDL) is necessary to operate this vehicle. The M2 112 chassis is only offered with air brakes which could mean an air brake endorsement is necessary on your license also.

Productivity leads to profitability. Whether you’re on the road or at a job site, it’s important to operate vehicles that perform efficiently and reliably. That’s precisely why Detroit builds the versatile DD13 engine with BlueTec® emissions technology. Detroit engineers know what works, and what doesn’t. That’s why the DD13 follows the common base engine design of its successful big brother, the DD15® engine. This engine is everything you need and nothing you don’t. In a time when economy means everything, the DD13 makes perfect sense. The fuel-efficient design makes the most of every gallon with an Amplified Common Rail System (ACRS™) that optimizes each injection event to minimize fuel consumption. Available exclusively in Detroit engines, ACRS works in unison with our DDEC® electronic engine controls to deliver the exact amount of fuel you need at the right moment, creating an optimal combustion event. All that work fine-tuning combustion means lower emissions, less engine noise and vibration, and less wasted time stopping at the pump. Everything, right down to the advanced cooling system that decreases fan on-time, was designed to minimize fuel consumption.
An extremely wide and flat torque curve maintains the power to keep the driver’s foot off the clutch and hands on the wheel for less shifting and fatigue.
With the DD13, drivers also will get a wider sweet spot that makes it easier to cruise along in the fuel-saving range. So, whether you’re navigating traffic or maneuvering through a construction site, the DD13 delivers great fuel economy. A three-stage integrated Jacobs® engine brake gives you more stopping power and quieter engine braking than ever before. And, thanks to its exceptional braking power, the Jake Brake also extends the service brake life. TORQUE RESPONSE IS THE KEY TO PERFORMANCE. THIS ENGINE WILL HAUL, CLIMB, PULL, MIX and DUMP WHEN AND WHERE YOU NEED IT. The DD13 design is based on a sturdy rear gear train and ribbed cast iron block to minimize noise, vibration and harshness (NVH).
The robust design provides a B50 life of one million miles, and, the waste gated, asymmetrical turbocharger has fewer moving parts than a VGT design, which improves performance, and reliability. The turbocharger also applies constant back-pressure to efficiently enable the EGR system, all of which add up to a dependable engine that gets drivers where they need to go, and makes work seem a little less like work. The DD13 also offers rear-engine power take-off as an option for certain applications, and, if all that isn’t enough, DDEC provides a complete offering of engine and driver performance reports to help you maximize the advantages of the DD13.

Fabrication & Exterior
The SportChassis body sub-frame consistsof .125 extruded aluminum tubing mounted to 1X3 inch solid aluminum sleeper rails. The sub-frame is spaced and reinforced in such a manner as to maximize carrying capacity while providing a near perfect surface for exterior skin attachment.
All body cutouts for lighting installation, jambs and doors, compartments and fender openings have no sharp edges or burrs, and are cut so that edges have a machine finish. By using CNC technology, consistent tolerance of 0.004” is maintained for absolute quality and maximum redundancy. This means if your vehicle is ever damaged, any blemished aluminum part can be replaced with its exact replica.
Each SportChassis compartment is CNC-routed and break formed to ensure tight tolerances and the utmost durability. The body compartment doors are constructed using .125 aluminum skins fastened to extruded frames and mounted in counter-extruded jambs. This allows our door to be flush with the body side skin when closed.
Stainless steel piano-type hinges run the full height of the door frame. As protection from the effects of electrolysis and galvanic corrosion, each exterior door has an inert barrier strip installed between the hinge strap and the door jamb. Each door is gasketed with a closed-cell neoprene gasket completely encircling the door with an unbroken seal. The seal does not come in contact with the striker pins, latches or hinges, which prevents the intrusion of moisture and/or dust into the compartments when the doors are closed. The body side skins are .125 smooth aluminum and are cut using CNC technology. Further, each side skin is attached to the sub-frame using aircraft technoligies.
To mate the skins to the frame work, SportChassis features a unique jig and trolley system. This means that the tubing is always square and that the welds, inner and outer, are applied and inspected at eye level. This insures a construction and weld quality second to none.
Once the bed is complete, it moves to the paint shop where computer-mixed materials are applied in an acclimated paint booth by some of the best finish artists in the business. The process ensures that finishes are consistent to mil specs and hold both their adhesion and luster for years of quality service.
After leaving the paint shop, it’s time for another full inspection and detailing. Ensuring that all components, installation, and materials exceed exception is a core mission of the Quality Assurance department. This staff of experienced professionals drawn from all areas of manufacturing process and possess the hands-on knowledge and expertise to recognize any problem or imperfection and eliminate it. Additional customization and branding finish out process including road tests, electronic shakedown, and that personal touch that concludes the journey from chassis to SportChassis.
