JE PRO SEAL PROFESSIONAL RACE SERIES For the professional racer JE Pro Seal now offers ring combinations with reduced axial heights and radial widths. The combination of reduced radial and axial heights enable these rings better cylinder wall conformability. These steel rings utilize advanced materials and coatings, which help reduce friction and provide better ring seal. These ring sets include, Ultra Finish Rings (UFR), Critical Finish Rings (CFR), and Critical Tolerance Rings (CTR). ULTRA FINISH RINGS JE Pro Seal Ultra Finish Rings (UFR) are held to the most exacting tolerances in the industry. Specifically designed to compliment our Ultra Groove custom piston options, these rings are finished to within +/-.000050" axial height to deliver unprecedented bore conformity and sealing properties. The lapped Ultra Finish process also yields extremely flat, smooth ring sides that result in a surface finish of less than 4 inRa (4 microinches). CRITICAL FINISH RINGS JE Pro Seal Critical Finish Rings (CFR) present an alternative to Ultra Finish Rings with the same surface finish 4 inRa) and a lapped axial height held within +/-.00015". CRITICAL TOLERANCE RINGS JE Pro Seal Critical Tolerance Rings (CTR) are held to +/-.00015 axial height and an industry standard 40 inRa) lapped surface finish. An alternative to our Critical Finish rings, JE Pro Seal CTRs are available in many popular ring types. Call your JE Pro Seal sales representative for availability. PRO RING SETS All new from JE Pro Seal, steel ring sets utilizing a high strength alloy steel top ring providing superior bore conformity, complimented by the outstanding seal and wear characteristics of a high velocity plasma moly inlay coating. Top ring weights under 10 grams achievable as a result of reduced ring radials and short axial heights helping to minimize cylinder wall drag. Optional 2nd ring Napier hook profile design help to improve oil control and efficiency.
