LN Engineering proudly offers JE Pistons. LN has a long history with JE Pistons, with the first Nickies Cylinders ever produced having been fitted with JE's 2618 forged alloy pistons almost 20 years ago.
Designed for Porsche Air-cooled 911 engines compatible with a Nickel Ceramic bore, these pistons are machined from forged 2618 alloy for greater strength. The valve pockets are machined to accommodate high lift cams, and accept the stock stroke and rod length. The ring grooves are precision CNC machined and all new applications include skirt coating and 3D under-crown milling. Piston clearances designed for aluminum cylinders; steel/iron cylinders may require additional clearance.
JE Pistons are optimized for use with Nickies cylinders, allowing for optimal piston to cylinder clearance for quiet operation and excellent longevity. Our custom forged pistons are the best of their kind. They feature the low-friction slipper skirts, low weight, balancing within 1/2 a gram, and are manufactured from the superior 2618-aluminum forged alloy material, which performs best when paired with our very own Nickies™ cylinders.

Where a factory Mahle piston best suits a factory Mahle cylinder, the proprietary alloy used for our Nickies™ cylinders is designed for optimal performance with a JE Piston.
