Wiseco Mitsu 4G64 w/4G63 Heads 10.5:1 E85 Piston Shelf Stock Kit

Forged from 2618 aluminum right here in the USA, these Wiseco pistons are built for serious performance, especially if you're running E85 fuel. They're designed for the 4G64 engine block when paired with 4G63 cylinder heads, giving you a solid 10.5:1 compression ratio that's ideal for boosted applications. The precision ring grooves and anti-detonation features are there to help seal the combustion chamber better and prevent issues under high stress.

You'll also find an ArmorGlide skirt coating on these pistons. This isn't just for looks; it helps reduce friction, keeps things quieter, and makes the pistons more resistant to seizing, which is crucial when you're pushing your engine hard. The fully machined crown and forced pin oiling are details that show these are made for demanding use, whether you're building a dedicated race car or a seriously upgraded street machine.

This kit includes a set of four pistons, each with an 85.00 mm bore and a 35.00 mm compression height. The pin diameter is 0.8661 inches. Remember, these are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
