BUILT TO PERFORM

Unmatched Durability

The full box-section rear frame resists torsional shock and twisting forces.

Heavy-duty steering cylinder mounts efficiently transmit steering loads into the frame.

Optimized axle mounting results in increased structural integrity.

Achieve longer component life with increased size of upper hitch pin, frame plate, and bearing.

Solid through-width push beams transfer and absorb stresses through a larger portion of the frame.

Features fully enclosed hydraulic wet disc brakes for improved performance.

Robust structures withstand the toughest conditions and multiple lifecycles to improve your bottom line.

In corner dozing, stresses are transferred and absorbed through a larger portion of the frame.
