FAQ
Is this pre-bled from the factory?Yes. The HYDX-F67.3 is supplied pre-bled to speed up installation and ensure proper hydraulic performance.
Will this fit my early-1999 truck?
Yes, as long as it is a 7.3L with the ZF-6 6-speed. This kit does not fit automatic transmissions.
Do I need a new clutch at the same time?
Not required, but it’s smart to refresh hydraulics when installing a new clutch—or vice versa—so release travel and pedal feel are optimized together.
Does this include the reservoir and line?
Yes. The assembly includes the master, slave, line, and reservoir components required for a direct install.
Will it work with upgraded performance clutches?
Yes—many owners pair South Bend hydraulics with South Bend clutch kits for stronger, more consistent release under load.
