JE Pistons Ultra Series Pistons (FA20 DIT)

Ultra Series pistons combine JE’s premium features and all-new, industry-first technology into an off-the-shelf piston kit! This includes aligned grain flow technology, a proprietary JE technology that aligns the grain flow in critical areas of the piston to improve strength, and several other high-end features.

JE's revolutionary Perfect Skirt coating is one of the many technologically advanced aspects of the Ultra Series. It protects the piston skirts, reduces friction, while eliminating cold-start piston slap and false knock on computer-controlled engines.

All Ultra Series pistons will come standard with ceramic crown coating to help reject combustion heat for durability and better exhaust scavenging characteristics.

Thicker, premium-material wrist pins are another, strength-boosting feature of the Ultra Series line. Combined with unique Grain Flow Optimized forging technology, the Ultra Series is ready for huge power.
