Description

JE Pistons are forged racing pistons, designed for top-level motorsports. This set of 8 pistons features 2618 material, a 4.155" (105.54 mm) bore, and a 0.927" (23.55 mm) pin diameter. The set includes pins (PN: 927-2750-15-51S) and retainer locks (PN: 927-042-CS) but no ringset. Designed for aftermarket race blocks, these big bore dome pistons accommodate larger valves and specific cam profiles, compatible with most 20° Wedge cylinder heads and moderate nitrous. They have precision CNC machined ring grooves for 1/16", 1/16", 3/16" rings. A pin upgrade is recommended for applications exceeding 700hp. Includes double spiro locks and pin oilers.
