Wiseco Chrysler 318 4.070in Bore 1.460in CH -20.00 CC Piston Set

If you're building a serious performance engine for your Chrysler 318, Wiseco's Professional Series forged pistons are a solid choice. These aren't your average replacement pistons; they're built from the ground up for demanding race applications where durability and consistent performance are critical. They're made in the USA from 2618 aluminum, which gives them improved tensile strength to handle the stresses of high-performance use.

Wiseco machines these pistons with precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal. This helps ensure that combustion pressure stays where it belongs, boosting power and efficiency. The piston crown is also fully machined, and they feature forced pin oiling to keep the wrist pins well-lubricated under extreme conditions. Plus, they come with an ArmorGlide skirt coating. This coating helps reduce friction, resist seizure, and even makes the engine run a bit quieter.

This set is for a 4.070-inch bore with a compression height of 1.460 inches and a -20.00cc dish. You'll get a set of 8 pistons, along with premium rings. Keep in mind these are intended for heavy to severe duty race builds and are not CARB approved, so they cannot be shipped to California.
