Ford has offered the ZF6 six speed manual transmission throughout the entire SuperDuty line (since 1999). It remained relatively the same, with the exception of bouncing between single, solid flywheel and dual mass flywheel. Overall, it has been a relatively stock clutch, but as with all things....STOCK IS STOCK! We offer replacement clutch kits from the two LEADING manufacturers in the world, South Bend and Valair. So, whether you're looking for a simple stock replacement, or a ceramic dual disc, or something in between, we've got you covered. And as always, if you've got any questions about which clutch is right for you, give us a call or send an e-mail to
cs@dieselpowerproducts.com and we'll help to steer you in the right direction.
