JE Pistons Kit ULTRA SERIES for Suzuki GSX1300R Hayabusa 2008-2018

The Ultra Series pistons are loaded with features that fall in the realm of custom, but are available off the shelf. Those features are highlighted below. 

POWERSPORTS ULTRA SERIES PISTON FEATURES

• Aligned Grain Flow Technology - In-house forging has allowed JE to develop proprietary forging technology that directs the grain flow of the aluminum to flow around critical areas of the piston, increasing strength

• Lateral Gas Ports - Channeling combustion gases to the back of the top ring groove adds pressure behind the compression ring to keep it pushed against the cylinder, providing improved and more consistent ring seal, critical in boosted applications

• Ultra-Thick Ring Lands - Aids in maintaining ring stability in forced induction and high-horsepower N/A engines, contributing to consistent ring seal and consistent power

• Thermal Barrier Crown Coating - Ceramic coating on the piston crown greatly reduces heat transfer into the piston material, decreasing fatigue and improving longevity

• Tuff Skirt - Proprietary, Moly-based dry film skirt coating is applied in-house and reduces operating friction for better wear resistance

• Accumulator Groove - Provides additional volume to trap unwanted gases that get past the top ring to keep pressure low and ring seal and performance high

• Double Pin Oilers - Two oil channels fed into the pin bore maintain proper lubrication to improve wrist pin and pin bore wear resistance

• Upgraded 9310 Wrist Pins - Stronger, thicker wrist pin material designed to withstand additional loads of forced induction engines • Complete Kit - Supplied with all necessary pistons, rings, wrist pins, and wire locks under one part number
