Description

Constructed from hypereutectic aluminum, these pistons feature a +22.0cc dome top with two valve reliefs and a 0.210" dome. They are precision-engineered with a 4.310" bore, a 1.640" compression height, and a 6.135" rod length, suitable for a 4.000" stroke. The piston rings grooves are 5/64" for compression and second rings, with a 3/16" oil ring groove width. The pin size is 0.990" O.D., accommodating press-fit or floating pin types. The DUROSHIELD coated skirt enhances longevity and reduces friction.
