JE Pistons BBC 4.610in Bore +.034 / 1.120 CH / 0.990 Pin - Set of 8 Pistons

Our new F.S.R. hollow dome GP (Gas Ported) piston line is designed for circle track and drag racing applications. They are lighter than traditional full round pistons (including wrist pin and rings), but are stronger and more durable due to an advanced FEA-designed forging.
