Platinum Series Pistons - 4.375 -12 Dished

These pistons are a 4.375" bore -12cc DISHED piston which will work in either a 440 block with our 4.500" stroke and 7.100" rod "543CI" stroker combination, or in a 400 block with either our 4.25" stroke and 6.535" rod "512CI" stroker combination, or our 3.75" stroke and 6.76" rod "451CI" stroker combination. All our platinum pistons use 1/16, 1/16, 3/16 ring pack for less frictional loss, and weight saving, full floating .990 pin size. The compression ratios and distance below deck will change slightly depending on which stroker combination you are using these pistons with. See our stroker kits page for more details.
