Wiseco Toyota 20R22R FLAT TOP 94MM Piston Shelf Stock Kit

If you're rebuilding the engine in your 1990-1995 Toyota 4Runner, especially for demanding performance applications, these Wiseco Professional Series pistons are a solid choice. They are specifically designed for the 22RE engine and come in a 94mm bore size, ready to be installed as a set of four. These aren't just standard replacement parts; they're built with serious builders in mind, offering improved strength and durability for heavy or severe duty use.

Wiseco crafts these pistons from 2618 aluminum, a material known for its high tensile strength, making them well-suited for the stresses of performance engines. They feature precision ring grooves, anti-detonation grooves, and other features aimed at improving ring seal and overall combustion efficiency. The piston crowns are fully machined, and they incorporate forced pin oiling to ensure the wrist pins stay well-lubricated. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly.

This kit includes everything you need to get your 4Runner's engine rebuilt with robust, high-performance pistons. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
