Description

As the leader in forged racing pistons, JE Pistons has applied over 75 years of experience to its range of Pro Series pistons. Pro Series® Piston kits feature purpose-built forging designs that reduce overall piston weight without sacrificing strength or durability. Internal and external strut braces significantly reduce stress on critical areas while ultra-flat ring grooves improve ring seal for better, sustained performance.

Features & benefits

Forged in the USA using 2618 aluminum, yielding high tensile strength needed for high-demand performance applications
Race-inspired two-ring design promotes quick revving and throttle response for noticeable power
Designed specifically for Suzuki RMZ450 Engines to provide optimized performance durability
Proprietary Forged Side Relief (FSR) forging design minimizes friction and power loss with reduced skirt width and saves additional weight with a shorter wrist pin
Includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings
Made 100% in the USA
Accumulator Groove: A specialty groove between the top and second ring provides added volume for blow-by gases. This helps reduce pressure between the rings, improving top ring seal and minimizing ring flutter at high cylinder pressures.
Double Pin Oilers: Deliver twice the amount of oil to the wrist pin as compared to the standard single pin oiler.
Pin Fit: The pin bore is precision honed to attain an exact pin clearance. Clearances typically range from .0003 to .0010 between the wrist pin and pin bore.
Proprietary Forged Side Relief (FSR) forging design minimizes friction and power loss
Engineered, forged and machined 100 percent in the USA
Je Pro Seal Rings Included
Low Friction Skirt
