FEULING OIL PUMP CORP. Adjustable Pushrods - Twin Cam 4065

If you're running larger lift cams or high spring pressures, factory pushrods won't cut it—they flex under load, robbing you of power and stability at higher RPMs. Feuling's adjustable pushrods eliminate that compliance with rigid 4130 chromoly construction and precision CNC machining, letting your valve train respond consistently to every revolution. Built for serious performance engines, these pushrods maintain critical oil flow to your top-end while maximizing horsepower and torque output without compromise.
