If you're rebuilding the engine in your 1993-1999 Mitsubishi Eclipse, Eagle Talon, or Plymouth Laser, this single forged piston from Manley Performance is a solid option. It's built with a 2618 alloy forging, which is known for its strength, and features an 86mm bore with a 94mm stroke, designed to work with the 4G63 engine.

They also pay close attention to the ring lands and grooves, ensuring a tight seal for better combustion efficiency. The included wrist pins are made from chrome moly, adding to the overall durability of the assembly.
