The AxleTech PRC673 planetary rigid axle is engineered to meet the demands of heavy-duty off highway market vocations. Typical vocational usages include fertilizer spreader, snow blower, tow tractor, loader, feller buncher, and special vehicle applications. This axle is widely accepted in the off highway vocational segments due to its broad axle capacity of up to 31,000 lb (14,000 kg).

The PRC673 planetary rigid axle series offers a wide selection of the overall gear reduction options, axle load capacities, brakes, and multiple tracks/axle mounting centers that can be tailored to your specific needs.

Engineered for compatibility with demanding traction conditions, The PRC673 meets the trend of increased driveline torques, tire sizes, and loading requirements that provide an extra ruggedness for prolonged life.

DCDL (driver-controlled differential lock) and NoSPIN® differential options are available for improved traction vocational requirements.

The PRC673 design helps reduce OEM/end-user maintenance costs. A standard carrier input pinion unitized seal reduces the likelihood of oil leaks. Extra axle housing magnets are optional to help reduce any metallic contamination between scheduled lubrication change intervals.

Service brakes are air actuated cam. Carrier input pinion mounted park brake option is also available. Cam brakes also have failsafe brake chamber options for the vehicle parking feature.
