      Product Information

      Features, Description, Reviews, Specs & Installation


      • Ideal Upgrade for Boosted 'Stangs.
      • Good Driveability.
      • Kevlar Based Disc.
      • Includes Throwout Bearing & Tool.
      • 10 Spline
      • Fits Late 01-04 GT, 99-04 Cobra, 03-04 Mach 1.


      Ideal Upgrade. If you are planning on a forced induction setup or already have one in your GT, Cobra, or Mach 1, it will only take a few launches before you'll roast your stock clutch. Or maybe you're just tired of the slow shifts, and have decided it's time for a better one. A SPEC Stage 2 Clutch will handle up to 530 ft-lbs of torque without the "on-off" feel of true race clutches, blending driveability and the ability to hold lots of power perfectly.

      Perfect for Weekend Warriors. The SPEC Stage 2 Clutches are designed for all mild to moderately modified naturally aspirated and power added engines, but can be used with stock power levels without sacrificing driveability or excessive wear characteristics. They are the perfect balance of driveability and durability that makes them a great choice for 'Stangs that see a lot of time on the street as well as the strip and track.

      Premium Quality. The SPEC Stage 2 Clutch combines superior holding power with the driveability you want by using premium materials. Each Stage 2 Clutch includes a high clamp pressure plate, pure Kevlar friction material and high torque sprung hub and disc assembly. 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 Aluminum Flywheel for this Stage 2 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.

        5 2001 Cobra - jOEo

        Now third clutch, original lasted 96K, 2nd 48K

        Didn’t realize 2nd clutch only rated to 300hp, this one is good for over 500hp. Pushing 330hp/324trq. natural to real wheel, with lighter steel flywheel, great combo!

        So far so good

        200 miles into the break in and it's going great. This clutch was put on my 03 centennial edition new edge. I love the fact that this clutch is a stage 2 with the feel that's closer to oem. Like the description states it's really not a on-off feel that you would expect from a after market performance clutch. Great product.

        2 2013 GT - JimmyH Installation Time: Shop Install Installation Cost: $1000+

        Not good

        Just paid 2000 dollars for new flywheel (1500hp) new Spectre stage 2 clutch, new master cylinder to match clutch. After 200 miles it will shake the filings out of your teeth at high rpms. For over 2000 dollars it sucks worse than stock. What a waste of money Spectre clutches and Ford motor sports flywheels are. Over 2000 and 2 weeks wasted. Way to go Ford.

        5 2003 Cobra - NicholasC Installation Time: Full Day

        Love this product

        I did the install myself. Everything went together smooth. Previous owner had a spec stage 3 clutch installed. Figured I’d give this one a try seeing as I’m still using the stock blower. Worked like a charm. No clutch chatter and street drivability is on point. Very easy to slip. No one and off engagement.

        5 2004 GT - JonathanH Installation Time: Full Day


        I have a gt with a bit of tasteful mods and the clutch went right along with them it’s rated for plenty of horse power, so I’m not worried about burning it up, takes all the abuse and is pretty firm to push the pedal down, real good race feel. I would recommend getting new clutch cable and fire wall adjuster because this clutch being heavy will stretch your factory cable out within a month.

        3 2004 Mach 1 - orangeMACH Installation Time: Full Day

        good clutch bad bearings!!!

        I installed this clutch, pilot bearing, throw out bearing on my mach 1. There was a bit of chatter. Nothing excessive, but to be expected with a Kevlar clutch. My gripe is the throw out bearing almost immediately started squeezing. I want to like the clutch as the feel and holding power are good. My recommendation if you want a spec clutch is to ditch the bearing for ford racing parts. If you do this you should be ok. 5 stars for performance 1 star for supplied bearings.
