The PPE Heavy Duty Forged Pitman Arm features a new forged design to take the abuse of running larger wheels and tires and/or from increased horsepower. This Pitman Arm is equipped with replaceable dual bearings and larger 7/8" bolt assembly for increased strength and durability. Intended to work with PPE’s Extreme-Duty Idler Arm, PPE 7/8” Drilled Center Link, or 7/8” drilled stock center link.
