Our close relationships with every major ring manufacturer in the world coupled with our own in house processing capabilities and continuous development agreements with top racing teams in every major racing series in North America has enabled JE Pro Seal to develop and implement innovative, high quality, cost effective solutions for todays demanding high performance piston ring requirements. These valuable relationships, combined with JE Pro Seals manufacturing capabilities allow us to offer our customers the most technically advanced choices of any ring supplier on the market. CUSTOM DESIGN AND MANUFACTURING TABLE OF CONTENTS Continuously working to improve piston ring technology available to the aftermarket consumer, JE Pro Seal now uses Ricardos Ring Modeling software, RingPak Pisdyn to optimize new piston and ring designs. This software package allows JE Pro Seal to predict the effect of design changes while still in the development stage. After computer, dynamometer, and ontrack testing we can then validate the proposed changes. This time saving procedure, when combined with our custom manufacturing capabilities, allows JE Pro Seal to deliver custom ring solutions with virtually infinite variability, faster than ever before.
