FEULING OIL PUMP CORP. Adjustable Pushrods - Evolution 4077

If you're pushing your Evolution engine beyond stock parameters—larger lift cams, higher spring pressures, or elevated RPM targets—factory pushrods will flex and rob you of power delivery. FEULING's adjustable pushrods deliver the column rigidity and valve-train stability needed to maintain consistent valve timing and maximize horsepower and torque output across the entire power band. Built from CNC-machined 4130 chromoly steel with minimal adjustment extension, these pushrods eliminate the guesswork and performance loss caused by traditional designs.
