Constructed from durable 2618 forged aluminum, these pistons are designed to withstand demanding conditions. The Pro Max series features a flat top piston style with a -4.0cc dome volume, suitable for achieving a 11.6:1 compression ratio when paired with appropriate cylinder heads and a 4.000-inch stroke. Key specifications for this piston set include a 4.030-inch bore, a 6.125-inch rod length, and a 1.110-inch compression distance. The pistons utilize a floating wrist pin style with a .927-inch diameter. It is important to note that this set does not include wrist pins or piston rings, which must be sourced separately. The piston ring thickness is specified as 1.5mm for the top and second rings, and 3mm for the oil ring.
