    Features & Details

    • Ideal Replacement.
    • Perfect for Your Daily-Driven 'Stang.
    • Organic Compound Disc.
    • Includes Throwout Bearing & Tool.
    • 10 Spline
    • Fits Late 01-04 GT, 99-04 Cobra, 03-04 Mach 1.
    Ideal Replacement. A powerful 'Stang needs a clutch capable of taking the heat. If enjoy launching your SN95, your OEM clutch might be starting to show signs of wear like slipping and that signature "burnt clutch" smell. Consider a SPEC Stage 1 as the ideal replacement for a 'Stang that sees daily driver duty - it will gives you the holding power and durability of high-performance clutches without the "on-off" feel of true race clutches.

    Daily Driver Friendly. This SPEC Stage 1 Clutch is designed for bolt-on naturally aspirated and mildly modified forced induction engines. It's best suited to 'Stangs that see daily driver duty and occasional track use, since it offers the most friendly pedal feel combined with SPEC's legendary durability.

    Premium Quality. The SPEC Stage 1 Clutch offers all the features you need from a more powerful clutch with superior driveability. SPEC Stage 1 Clutches feature their signature high clamp pressure plate combined with a steel-backed and multi-compound woven organic material disc and high torque sprung hub. Like with all SPEC Clutches, an alignment tool is included for easy installation.

    Value, Performance, Durability. When looking for a new clutch, trust Spec for the best in value and performance.

    This Spec Clutch requires the use of a Spec flywheel for proper engagement. AmericanMuscle highly recommends the Steel Flywheel for this Stage 1 Clutch for optimum results. See the drop down menu option above.

    Technical Note. Because Ford made changes to the Mustang GT and Bullitt in mid year of 2001, be sure to check and see what kind of transmission type you have before ordering.

    Do I have to use a spec flywheel? I have a brand new Ford Performance Billet Steel 6 Bolt flywheel. The same one on here.

    • Yes, a spec flywheel is required to be used with the spec clutches for proper operation.

    • With a Spec Clutch, you'll want to get a Spec Flywheel for perfect engagement and clearance. You'll also want to get the Clutch Adjuster Kit to prolong the life of your new clutch and improve shifts. I've attached the link below for the adjuster kit so you can take a look! Don't hesitate to contact us if you have any other questions!

      Eats threw clutch cables

      Wish i never bought it. Clutch is to heavy for a daily and makes chatter noise. The first clutch cable was installed when clutch was done, it lasted a year. That cable was a steeda unit, which snapped, total garbage. Then installed a ford oem cable and got just over 5 years out of it. Mind you that's only 15k miles since its a weekend car. Then today a nice saturday went to pull her out and can not shift into any gears. Cable stretched this time. Tried adjusting multiple times and its obvi maxed out. Going to replace the cable again with ford oem, then later down the road replacing clutch with oem ford unit. That's what I should of done in the beginning.

      I've had the clutch before works really great american muscle always has extremely fast shipping the only bad side is the clutch release bearing/throw out bearing is already starting to chatter and squeal only after 100 miles or so I'm Still in the break in period of the new clutch and flywheel so I haven't performed any hard launch's or hard shifts guess I'll be ordering a ford racing TOB

      Spec Stage 1

      I'm not impressed. I had a ram in my last mustang and loved it. I decided to go with a spec for my mach 1 because I heard they are better. This clutch chatters more than any clutch I have seen in my life. I called spec and they weren't helpful in the least. The only good thing about this clutch is the feel of it, it is extremely easy to press it in. I resurfaced the fly wheel and got all of the components needed for an aftermarket clutch. This is just a terrible clutch, I definitely recommend a ram clutch over this.

      Excellent clutch

      Great clutch for your N/A mustangs and mild FI stangs. Great grab, much smoother than stock clutch. Once you break it in, you can floor it with no worries of overpowering your clutch. As my mechanic would say "now you can really get jammin' "

      flat out terrible..

      clutch chatter since day 1.. never went away, and pull it out 5,000 miles later and burn marks everywhere. Now i'll have to be getting a new flywheel as well as going to a RAM stg3. Don't waste your money on this paper weight.

      junk bearings in a junk clutch

      Installed the clutch everything went good felt really good, improvement over stock. Drove it easy for a day came onto it a little and I heard a bearing howling. Took it apart and saw that the garbage pilot bearing which was included in the kit had crapped out, i believe the release as well. I bought some ford oem ones as i don't have the time to wait for Ford Racing to be shipped in. I hope the oem ones will be sufficient. I tried contacting Spec but im sure they wont do anything for me so I will have to eat a few hundred bucks to have it installed again. Spend the money on a zoom clutch or centerforce dont cheap out like me, or the extra money you spend taking it out and in will equal that of a good brand.

      Good Clutch

      Installation was straightforward. Performance is great, much smoother than stock and sticks well. I haven't popped it yet since I'm still breaking it in, but its already a great improvement over stock.

      spec clutch

      i have two mustangs both equipped with spec clutches satisfied with both but recomend using ford racing pilot and throwout bearings the specs go out quick and can cause some damage, for the clutch chatter make sure its adjusted proper when first installed some clean up after breakin and i only heard that the stage plus that seem to do it

      Throwout Bearing …

      No problems with the clutch its self how ever im very disappointed in the performance of the bearings, 1000 (very easy) miles on the new setup with the bearing being the only problem, Solution? Buy the ford racing bearings!

      The clutch works great! i can burn out once again! :) ZERO chatter or sqeaking. I will say that the engagement between gears its not as smooth as it was... not sure why, but im assuming it was an error on my part :p

      Stage 1 Clutch

      This is an excellent replacement for an OEM clutch. The one thing that I do not like is that there is a little bit of chatter here and there when releasing the clutch in first gear but that is normal with racing clutches. Shipping took 2 full weeks but I guess thats what you get for free shipping. Overall Great item for the money.
