The SportChassis RHA-450


About the RHA-450

RHA-450 Bigger Better Faster Stronger… those are the words that come to mind when you climb behind the wheel of a RHA-450. The SportChassis RHA-450 is equipped with the largest availiable engine in its class -- the Detroit Diesel DD13. Utilizing the DD13 engine means power and torque when you need it. The DD13 exerts 450hp and a whopping 1650 ft/lbs of torque. With a peak torque range of up to 500 RPM—from 1,100 to 1,600 RPM. The robust construction extends our track record of engines with a B50 life of one million miles. For trailer loads that weigh up in the 30K -40K range, the 112 chassis is your best bet to pull and stop the load safely. We can utilize this engine in any or our current 2-Wheel Drive SportChassis models. RHA114-450 Red 1 Things to note when stepping up into this chassis: Due to the Gross Vehicle Weight Rating (GVWR) a Commercial Drivers 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.
