All converters will come with Billet front cover, new full Billet lock-up assembly (unless otherwise noted), furnace brazed and tig welded turbines for increased strength, and torrington bearings for longer life and reduce internal friction.
Singles are capable of 500hp with adequate line pressure. These are rebuilt with a used billet cover and stock internals. They are a low cost alternative for trucks with just a tuner that tow and want the strength and reliability of the billet front cover.
Triple disc are capable of 800HP with adequate line pressure. These are built with new a billet cover and apply piston.
A billet input shaft is recommended when going with any three, four, or five disc converter.
