Bullet Series pistons are forged from 2618 alloy, FEA designed and balanced to within one gram across the set, with dual forced pin oilers, accumulator and contact reduction grooves and a forged side relief that holds up under boost or nitrous. This set is machined for the Gen 3 Coyote at the standard 3.6614 in bore on a 5.932 in rod with a 1.165 in compression height, and the 8.04cc dome takes the engine to a 12.0:1 compression ratio. Every set ships complete with its matching ring pack, gas nitrided steel barrel faced top rings, Napier taper hook groove second rings and a three piece nitrided oil ring, plus chromoly wrist pins and wire locks.
