Piston 350, Forged .070 W-31


SKU: PSTN350W3170-1 Categories: , ,


Look no further. A true remastered W-31 piston in a forging that is made right here in the United States. We also added performance details in this design. We start with a 4032 forging which has addition silicon content. This helps prevent expansion and enhances mechanical longevity due to design. It is also a quieter running piston as well.  This piston set includes 8 wrist pins and 8 forged .070 over pistons. Will accept a 1/16th, 1/16th, 3/16th ring package. Intended to be used with the factory style connecting rods.
