Description:
JE Pistons' FSR hollow dome GP pistons, available in a 350 or 400 Series, are the forged side relief versions of their popular 23-degree domed pistons, and they are ideal for circle track and drag racing. Up to 70 grams lighter than traditional "full round" pistons (including wrist pins and rings), these hollow dome gas-ported pistons are also stronger and more durable due to modern FEA-designed forging. They feature accumulator grooves, contact reduction grooves, double pin oilers, lateral gas ports, and deeper valve pockets to accommodate higher lift cams and milled cylinder heads. JE Pistons 23-degree 350 and 400 Series FSR hollow dome GP pistons will accept a low-friction .043/.043/3.0mm ring package (not included).
