Manley 93.5-99 Eclipse GST/GSX 4G63T 85mm Bore 10.0/10.5:1 Dish Piston Set with Rings

Manley Performance is well-known for building strong engine components that professional builders trust. If you're working on a 1993.5-1999 Mitsubishi Eclipse GST or GSX with the 4G63T engine and need to rebuild or upgrade your engine's short block, this set of 85mm bore pistons is a solid choice. These pistons are designed to handle the demands of performance tuning and racing applications.

These pistons are forged from 2618 alloy, a material chosen for its exceptional strength and ability to perform under high stress. They feature proven cam and barrel skirt profiles, which help generate power efficiently while also being kind to your cylinder walls during operation. Manley also pays close attention to the ring lands and grooves, machining them to strict standards to ensure a better seal from your piston rings, which translates directly to more power. The included wrist pins are made from Chrome Moly, offering good durability for most performance builds. For those pushing the limits, Manley's unique manufacturing process ensures the ring grooves are perfectly square to the piston skirt, a detail that matters for consistent sealing and power delivery.

This set includes the pistons, rings, and wrist pins. 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.
