      Description

      Ideal Replacement. Your Mustang is putting down serious horsepower and torque, but is your clutch able to handle it? If your clutch is starting to slip, or you're starting to smell that signature "burnt" clutch smell, it's probably time for a replacement. SPEC Clutches are the perfect choice that will improve your drivetrain's ability to handle power and perform reliably.

      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.

      Application. This SPEC Clutch is designed for V6 Mustangs made between 2005 and June 6th 2007. Ford made some changes in the V6 during the 2007 production year, so if you're not sure which SPEC Clutch you need, please contact us.

      Technical Notes:

      • The 2005-2010 Mustang uses a concentric slave cylinder instead of a conventional throwout bearing.
      • Therefore this clutch kit will not include a throwout bearing.
      • V6's built from 2005 to December 2006 will use Spec flywheel part# SF66A or can reuse the factory flywheel with the SF66 Clutch.
      • V6's built from January 2007 to June 6th 2007 must use Spec flywheel part# SF66A with the SF66 Clutch.
      • V6's built from June 6th 2007 to present must use Spec flywheel part# SF66A-2 with the SF66 Clutch.

      Fitment: 2005 2006 2007 Details

        1 2005 V6 - Ally Installation Time: Full Day

        Worse than OEM

        I put the Spec Clutch and lightweight flywheel in my 2005 v6, after about 700 miles *still in the break in period* the car slowly but surely became undriveable. After bleeding the clutch again, and flushing the transmission fluid and nothing seeming to help-- I last resorted in taking it to the shop to figure out the issue. Upon pulling the transmission and examining the flywheel and clutch, it was evident that one of the clutch springs had came loose and cut grooves into the flywheel. I contacted Spec for the warranty (because it was within the 120 days after the purchase date), sent in pictures and told them what happened and was basically told that it was 'normal wear and tear,' which is not even remotely true. Then I was told that I would need to spend my own money to send in the faulty parts with no guarantee that Spec would send out new parts instead of the old faulty parts. Not to mention, every person at Spec that I've spoken to has given me nothing but god awful customer service.

        5 2006 V6 - BrentR Installation Time: Weekend

        Works great

        Pretty easy install. I had the flywheel resurfaced and installed a new pilot bearing in the flywheel. Ended up getting the pilot bearing from local Ford Dealer. Couldn’t find the correct one online. The alignment tool worked great. I was careful to have it perpendicular to the clutch when I tightened the pressure plate. Transmission slid right in. The clutch has a softer pedal feel than the factory. Other guys told me this is typical of Spec.

        4 2006 V6 - LuisX Installation Time: Afternoon

        Good improvement

        The difference can be noted. Tires now screech when second gear is applied and pedal feel softer. But now the input bearing sounds when engine gets warm. So keep in mind that probably your transmission will need be worked too after this modification.

        Great replacement!

        My old clutch was on its last breath. Shifting was terrible and I'd always here a squeal when going into first. Not only is that gone but I feel a slight increase in power when I launch into each gear! Great for a daily driver

        4 2007 V6 - 07PhillyStang Installation Time: Weekend

        Night and day difference

        After 142K miles on the original clutch I decided it was time for swap and selected the Spec stage 1 clutch with aluminum flywheel. Everything fit perfectly, stock OEM hydraulic throw-out bearing can be used (of course recommend you replace if doing this job), and the flywheel even came with the pilot bearing already seated. The first time you fire the car up though BE WARNED, this thing BITES HARD. Of course a change in pedal feel is expected with any clutch upgrade but holy smokes batman, as someone who has driven nothing but a manual daily for over 15 years I stalled the vehicle 4 times in rapid succession trying to get a feel for things. Still in the recommended 500 mile break in period so cant speak to longevity but will say once you become familiar with the new pedal feel you will definitely enjoy this setup.

        2 2006 V6 - ctross Installation Time: Afternoon

        No pressure

        I chose this as replacement for my OEM clutch under the understanding it would have a similar feel to the stock clutch. Quite the opposite and very dissatisfying. My stock clutch felt very stiff/firm in a good way. I could tell when it was engaged and disengaged. This Spec clutch has way too much give and I have to press (which is a strong word as it feels like it just falls now) the pedal completely to the floor now before I can shift.

        Holy light clutch batman!

        I'm just going to start by saying this clutch is reeeeeaaaaally light if you going from the factory clutch like I did. Seriously, my buddy and I spent probably an hour more than we needed wondering what was "wrong" with the clutch and why it was taking so long to bleed it. But the product itself is excellent, there were no issues in the install (took maybe 10 min to put the disc and plate in and tighten all the bolts) it's really easy to use and it grips really well, it's an excellent replacement to the stock clutch.

        Excellent upgrade

        I have a 2006 v6. It took the shop only a few hours and it is great. It'll take you a second to get use to it. It is like driving a whole new car. I also got the flywheel. I usually not one to believe the reviews and what but definitely a great buy.

      change Flywheel (lighter)is it important ?

      • While you may be able to resurface your factory flywheel, we highly recommend getting a matching Spec flywheel for the best fitment and performance, as resurfacing the factory flywheel may not provide the correct fit. We offer the Spec Billet Aluminum Flywheel, item number 60029, which is a match to this clutch and can be found here: https://www.americanmuscle.com/spec-aluminum-flywheel-05v6.html

      Does the June 2007 cutoff represent the production year or model year? I have a 2007 V6 mustang, but it was made in November of 2006. Should i buy this or would it fall into the other category as it would technically be a 2007 mustang produced in november?

      • The cutoff date would refer to the actual manufacture date of your Mustang. Since your Mustang was manufactured in November of 2006, this Spec Stage 1 Clutch would fit.

      • The Spec Stage 1 Clutch will include the clutch disc, pressure plate, and alignment tool only.
