Good To Know

Q: Is this piston compatible with stock crankshaft? A: Yes, the .100 over bore piston works with the stock Banshee 350 crank, but ensure your cylinder is bored to match.

Q: What fuel should I use? A: High compression pistons typically require premium unleaded fuel or race gas; consult your engine builder for tuning.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
