What is the compression ratio of these pistons?

These JE Pistons feature a 7.0:1 compression ratio. This is often chosen for high-performance applications, especially those involving forced induction like turbochargers or superchargers, or for engines built for extreme durability.

What materials are these pistons made from?

The pistons are forged from 2618 aluminum, a material known for its high tensile strength. This makes them well-suited for high-demand performance applications where durability is critical.

Are these pistons legal for use in California?

No, these pistons are not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

When you're rebuilding the engine in your Renault R5 and aiming for serious performance, a strong set of pistons is where you start. This set of five forged pistons from JE Pistons is built to handle the demands of a high-performance engine, offering a 7.0:1 compression ratio that's ideal for boosted applications or engines built for durability under stress.

JE Pistons has been making forged pistons for over 75 years, and they build these right here in the USA using 2618 aluminum. This material gives them the high tensile strength needed for demanding use. They've incorporated their proprietary Forged Side Relief (FSR) design, which helps minimize friction and reduce weight by using a shorter wrist pin and narrower skirt. Depending on the specific application, you might also find an accumulator groove to help reduce combustion gas pressure, improving ring seal, and a skirt coating to cut down on friction and wear, which also helps quiet things down. This kit comes complete with high-quality wrist pins, locks, and JE Pro Seal premium piston rings, so you have everything you need to get them installed.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're building a performance engine for your R5, this set is a solid choice for durability and optimized performance.
