What does the '.020' mean on this piston?

The '.020' indicates that this piston is sized for an engine cylinder that has been machined to be 0.020 inches larger in diameter than its original factory size. This is common when rebuilding an engine to clean up wear or damage on the cylinder walls.

How many pistons do I need for my engine?

This piston is sold individually. Since most 134 ci engines have four cylinders, you will need to purchase four of these pistons to complete the rebuild.

Does this piston come with rings?

This Omix piston is sold individually and includes the wrist pin. Piston rings are typically sold separately and are not included with this part.

Product Details

When you're rebuilding a worn-out engine, replacing internal components is key to getting back that original performance. This replacement piston from Omix is designed for 134 cubic inch engines found in a wide range of Willys and Jeep vehicles from 1941 through 1971. It's a .020 inch overbore size, meaning it's intended for cylinders that have been machined to a slightly larger diameter to clean up wear.

Omix offers these pistons as a well-built replacement part to help you bring your engine back to life. They include the wrist pin and are sold individually, so you'll need four for a complete engine set. This piston is specifically sized for engines that have been bored out by 0.020 inches to address wear on the cylinder walls.
