About this part

Product Details

If you're rebuilding the engine in your 1993-1999 Mitsubishi Eclipse, Lancer, Eagle Talon, or Plymouth Laser, these Manley 85mm flat-top pistons are a solid choice. They're built from 2618 alloy forgings, which are known for their strength and ability to handle the demands of performance engines. This set includes the pistons, premium chrome moly wrist pins, and rings, all designed to work together for a better seal and more power.

Manley uses a unique process that machines the skirt profiles and ring grooves in one operation. This ensures the ring grooves are perfectly square to the piston skirt, which helps the rings seal better against the cylinder walls. The cam and barrel skirt profiles are also carefully designed to make good power while being easier on your cylinder walls during operation. This attention to detail means you get a well-built piston that's ready for serious use.

This set is designed for a standard 85mm bore and offers a 10.0:1 or 10.5:1 compression ratio, depending on your cylinder head volume. Remember 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 details.
