Wiseco Chevy LS Series -25cc Dish 4.000inch Bore Piston Shelf Stock

Starting with a 4.000 inch bore and a -25cc dish, these Wiseco pistons are forged from 2618 aluminum right here in the USA. This material choice is key because it offers improved tensile strength, which is exactly what you need when you're pushing an engine hard. They're designed for heavy to severe duty race builds, meaning they're made to handle a lot of stress and heat without failing.

You'll notice the precision in the ring grooves, along with features that add extra ring seal. Plus, they come with an ArmorGlide skirt coating. This isn't just for looks; it helps reduce friction and noise, and it's resistant to seizing, which is a common concern in high-performance engines. The fully machined crown also adds to the overall durability and performance of these pistons.

These are sold individually, so be sure to order enough for all your cylinders. They're a solid option if you're building a serious LS engine for racing or extreme performance use.
