The reasons that I like tripods over CVs are that they are more efficient than CVs up to a joint angle of 8°, their service life in high-power applications is vastly greater, and they don’t need an exotic and annoying grease like Krytox in high power applications. Krytox is an amazing grease, but the only effective solvent for it is freon. Freon is not exactly a practical solvent. At Hall Racing, we went from having to do CV maintenance every day at...
