Product Details
Omix has been a go-to for Jeep replacement parts for a long time, and they make solid components to get your rig back in shape. When you're rebuilding an engine, especially in a Jeep where you need every bit of power, replacing worn internal parts is key. This is a cast replacement piston designed for 4.2 liter engines that have been bored out an additional 0.020 inches over their original size.
This piston is built to help restore your engine's original performance after wear has taken its toll on components like the cylinder walls and rings. It's a direct replacement for the original part, meaning it fits right into your engine's setup. Remember, you'll need six of these for a complete engine rebuild, and they are sold individually.
This piston fits a wide range of Jeep models from 1979 through 1990, including CJ5, CJ7, Wrangler YJ, and J-Series trucks. Please note that this part is not CARB approved and cannot be shipped to California.
