JE Pistons RENAULT R5 7.0:1 Set of 5 Pistons

Starting with a 2618 aluminum forging, these JE Pistons are built for serious performance in your Renault R5. This set of five pistons is designed to meet the demands of high-output engines, offering a 7.0:1 compression ratio with a dome piston design. Each piston is forged and machined entirely in the USA, leveraging JE Pistons' extensive experience to create a durable and powerful component for your engine build.

JE Pistons incorporates several design features to enhance performance and longevity. The proprietary Forged Side Relief (FSR) design uses a reduced skirt width and a shorter wrist pin to minimize friction and power loss, while also saving weight. Depending on the specific application, an accumulator groove can help manage combustion gas pressure, reducing ring flutter and improving the seal for consistent power delivery. A skirt coating, also application-dependent, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

This piston kit comes complete with high-quality wrist pins, locks, and JE Pro Seal premium piston rings, ensuring you have the essential components for installation. The 3.071-inch bore size and 0.787-inch pin diameter are specified for this particular application. Please note that this kit is not CARB approved and cannot be shipped to California. It's crucial to consult the manufacturer's installation instructions for proper fitment and assembly procedures.
