Thermoplastic CV/J Boot Seal

The first global implementation of a blow-molded, thermoplastic elastomer (TPE) constant velocity joint (CVJ) half-shaft drive-axle boot seal used on 1984 MY E/K platform produced by then General Motors Corp. (was selected as the 2014 Hall of Fame winner. This application was a far more robust CVJ sealing solution that also was lighter, more durable, and less costly than the injection-molded rubber boots it replaced. It has been in continuous use on GM cars and trucks for 30 years, and 85% of front-axle CVJ boot seals on light-duty vehicles worldwide now use TPE in this application.
