Ultra Series combines all our premium features and a revolutionary
new forging technology into an off-the-shelf piston kit! This in-
cludes an Aligned Grain Flow Forging, a proprietary JE technology
that aligns forging grain flow in critical areas to improve strength.

Designed for Power: Every feature on Ultra Series Pistons are optimized
to perform flawlessly in high horsepower racing engines. This includes
lateral gas ports, thicker ring lands, and dual pin oiling.

Aligned Grain Flow Forging: Exclusively available on SE Ultra Series,
these optimized 2618 alloy forgings offer added strength over traditional
2618 forgings.

“Perfect Skirt” Coating: This patented skirt coating reduces friction and
provides a tighter clearance that eliminates cold-start slap and false knock
on computer-controlled engines.

Thermal Barrier Crown Coating: This ceramic-based coating reflects heat
into the combustion chamber, therefore reducing piston crown temperatures
and improving exhaust gas scavenging.

9310 Alloy Wrist Pins: These high strength, premium thick wall wrist pins
are manufactured by Trend Performance in the USA
