Wiseco’s Pro True line of pistons has always represented a huge value for the money, offering forged slugs with high-end features without the high end price. Unfortunately, LS engines have been left out of the mix – until now, that is. The newest addition to the Pro True lineup is their PT124, which is designed to use stock (or stock-dimension aftermarket) rods with .943″ pin diameter.
They’re ideal for budget-minded builds where piston quality is important, and they’ve got a lot of the features you would normally find in a high quality set of Wiseco Pistons – All applications are CNC machined with symmetrical valve pockets and feature pressure fed pin oiling with precision finished full floating pins.
Small .090” dome adds 4cc to raise compression slightly from stock
Designed for nitrous use – .280″ top land, 2618 forged alloy
Valve pockets accommodate LS1/LS2/LS3/LS6 stock cylinder heads and any cathedral port aftermarket head
ArmorGlide® skirt coating and a skirt shape that make these some of the best wearing, quietest forged pistons on the market
