Manley Mitsubishi 4G63 Stroker -22cc Dish 85.5mm Bore +5mm Extreme Duty w/ Ring (Set of 4)

When you're building a high-performance Mitsubishi 4G63 engine, especially one that's being stroked for more displacement, you need pistons that can handle the increased stress. This set from Manley Performance includes four Extreme Duty pistons, each featuring a -22cc dish and an 85.5mm bore, designed to work with a +5mm stroke setup. These aren't just standard replacement parts; they're built for serious engine builds where reliability and power output are paramount.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their strength and ability to perform under demanding conditions. They also feature proven cam and barrel skirt profiles, which help reduce friction and wear on your cylinder walls while still generating substantial power. The ring lands and grooves are machined to exacting standards, ensuring a tight seal for better compression and more power. Each set comes with premium chrome moly wrist pins, and Manley's unique fixturing process allows for skirt turning and ring groove machining in a single operation, which guarantees ultimate squareness between the ring groove and the skirt.

It's important to note that these pistons are not CARB approved and cannot be shipped to California. If you're looking to build a robust 4G63 engine that can withstand significant power, this set of Manley pistons is a solid option.
