Manley Mitsubishi 4G63 Forged Dish Piston Set - 85.50mm Bore 10.50:1

When you're rebuilding the heart of your Mitsubishi 4G63 engine, you want parts you can trust. This Manley forged dish piston set is designed for that purpose, featuring an 85.50mm bore and a 10.50:1 compression ratio. These pistons are built using Manley's signature "Platinum Series" construction, which starts with domestic 2618 alloy forgings known for their strength and performance under demanding conditions.

Manley takes a meticulous approach to machining these pistons. They feature proven cam and barrel skirt profiles, which help generate power efficiently while also being considerate of your cylinder walls during operation. The ring lands and grooves are held to strict standards, ensuring a solid seal for improved power output. For added durability, this set includes premium chrome moly wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the piston skirt, a detail that matters for long-term reliability.

This set is a solid option for serious engine builders. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete build, you'll want to ensure you have the correct piston rings and connecting rods that are compatible with these 85.50mm pistons.
