Another addition to JE’s strong lineup of circle track pistons is our all-new, 13-degree small block Chevy design. We worked closely with engine builders to design a dome and valve pocket profile that fits almost all aftermarket 13° SBC cylinder heads on the market.

• Vertical gas ports help provide strong and consistent top ring seal

• Contact reduction grooves reduce operating friction and minimize pressure, promoting more power

• Power-adder accumulator groove traps excess gases to help prevent ring flutter, aiding in consistent ring seal and power delivery

• Double pin oiling with broaches maximizes wrist pin and pin bore lubrication, improving longevity through reduced friction

• Ultra-groove ring groove operation provides unmatched surface flatness, promoting consistent ring seal

• Specially designed dome and pocket profile to fit many aftermarket SBC 13° cylinder heads
