New Product   1979-93 Fox Mustang Hydraulic Clutch Install

The next evolution in the Fox bodied cars is replacing the cabled clutch system with hydraulic actuation.

The cable system was a big improvement over the mechanical linkage of 70's and earlier vehicles.  Now for another stepped improvement in smoothness and reliability we offer a hydraulic master designed specifically for the Fox bodied cars of the 80's and 90's. 

At Modern Driveline it has always been our goal to make the going easier, more fun, and certainly efficient for special interest car enthusiasts around the world. Our business foundation has long been Ford’s legendary and timeless Mustang. And that’s because our core passion as enthusiasts has always been Mustang.

In recent years our growth has been centered on all kinds of popular special interest automobiles — Chevrolet Camaro, Chevelle, Tri-Five Chevys, Corvette, Cobra kit cars, Sunbeam Tiger, Ford Flathead and Y-Block V-8s, and more. If you’ve been thinking about a driveline conversion for your classic or late-model performance ride chances are good we’ve thought about it too. We’ve developed a wide variety of five- and six-speed conversion packages, cable clutch improvement kits, and light-pedal effort hydraulic clutch packages for all kinds of popular automobiles..

We’ve invested an enormous amount of time developing our new 1979-93 Fox Mustang hydraulic clutch kit as an added complement to our new T-56 Magnum six-speed, heavy-duty TKO, and original T-5 five-speed for the fabulous Fox. To say this research and development has been challenging is putting it mildly. We had what we believed was a solid working system. However, we’ve found variations in Fox Mustang firewall stampings and pedal support structure, which made it necessary to revise this low pedal effort hydraulic clutch system to where it was easy and enjoyable to use in all Fox Mustang applications. The challenge was formidable. We want the challenges here at Modern Driveline — not in your garage.

Introducing the 1979-93 Fox Hydraulic Clutch System for one of the most popular Mustangs in history. Our system works with both external and internal clutch slave cylinders, both available from Modern Driveline. We’re going to show you how easy this system is to install, then, invite you to take it for a test drive for the easiest clutch modulation and shifting you’ve ever done in your life. Our 1979-93 Fox Mustang hydraulic clutch development has been performed on two Mustang engineering mules hence the two colors visible in this installation article. Count on excellent fit and minimal adjustment when it’s time to tackle your Fox Mustang hydraulic clutch project. If you have any questions our world class tech support team is here to serve you.

Tools For The Job

You’re going to need:

  • Electric Drill (3/8”)
  • 5/16” Drill Bit
  • SAE Allen Wrench Set
  • 10mm, 12mm, 13mm Open End/Box End Wrenches
  • ˝” Open End/Box End Wrenches
  • ˝” Socket Wrench, 3/8” Drive Ratchet
  • Vise Grips
  • Small Common Flat-Blade Screwdriver
  • Silicone RTV Sealer
  • Loctite
  • A reliable friend

Safety is always our highest priority at Modern Driveline. It should be your first thought when you step into the garage to install our Fox Mustang Hydraulic Clutch Kit. Always support your vehicle at the frame rails with heavy-duty 2 or 3-ton capacity jack stands, and never with a hydraulic jack. Never trust your life to those dated stamped steel tubular jack stands, which can fold and collapse. Check vehicle and jack stand security before going underneath your Mustang. Always wear ANSI-approved safety glasses and/or a face shield. Wear proper gloves to protect your skin from hot surfaces and corrosive fluids.

Before getting started on your Fox hydraulic clutch conversion from Modern Driveline disconnect the battery negative cable. Because we have paid close attention to detail developing this kit for easy installation most of what you’re about to do can be performed by feel and can be accessed from just above the accelerator pedal. You don’t have to remove the steering column or pedal support.
