About this part

Product Details

Manley Performance is well-known for building robust engine components, and their Platinum Series pistons are a prime example of that commitment. This piston set is specifically designed for the Mitsubishi 4G63 engine, featuring an 86.5mm bore and a +1.5mm oversize. They are engineered with a -8cc dish to achieve a 9.0/9.5:1 compression ratio, making them a solid choice for engine rebuilds where enhanced performance is the goal.

These pistons are forged from 2618 alloy, a material chosen for its superior strength and ability to handle demanding conditions. Manley uses proven cam and barrel skirt profiles that help generate power efficiently while also being considerate of cylinder wall wear. The wrist pins are made from tool steel for added durability, and the ring lands and grooves are machined to strict standards to ensure excellent ring seal, which directly translates to more power and better engine efficiency. Manley's unique fixturing process allows them to machine the skirt and ring grooves in one operation, ensuring the ring grooves are perfectly square to the skirt for optimal performance.

This set includes the pistons and rings needed to get your 4G63 engine rebuilt. Please note 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.
