*** IN STOCK SHIPS TODAY *** RBS realizes the importance of a quality crank seal so we are proud to offer this Buna rubber crank seal to fit the RCD internal bearing support Hemi gear drive. If the racer is running the PSI spline or RCD keyway hub this seal will work but if going to the RCD spline crank hub the seal must be changed to work with the new crank hub.
Seal works well for alcohol but a racer should purchase the Viton seal if running nitro. Seal measures 2.878" O.D. x .450" thick x 2.075" I.D. where the hub rides.
