The 72mm piston assembly is a stock factory flat-top piston similar to the 70mm pistons in the Predator 212 Hemi and Wildcat 223.

These pistons use the standard 18mm(.709-inch) diameter wrist pins, which means you can use many factory-cast rods or stock-style billet and forged rods. The 72mm factory-style piston that is 70mm +2mm(+.080) over makes it an affordable option for cheater-stock or claimer classes to get more displacement without needing a billet rod or specialty piston.

Piston Weight: 158g

Piston Compression Height(Wrist Pin Centerline to Piston Crown): .9035-inch
