    Ideal Replacement. Your 2011-2014 GT Pony is a true muscle car in every sense of the word, but if you enjoy driving it hard, your clutch might not be able to handle all that power and torque.

SPEC Clutches are the perfect choice to 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 are driven daily and occasional see the track, since it offers the most friendly pedal feel combined with SPEC's legendary durability.

    It's recommended that you add an SR Performance Braided Stainless Steel Hydraulic Clutch Line during your new clutch install. Stock plastic clutch lines can fail during aggressive driving. Stainless steel clutch lines help prevent gear lockout and provide superior clutch pedal feel, even under the toughest conditions.

    Technical Note. It's recommended to install a new SPEC flywheel with this replacement clutch for the 2011-2014 Mustang GT. Please view our flywheel page for steel and aluminum flywheel replacements.

        Is a new flywheel required? I know that it is recommended but is a new flywheel required or will the clutch fit without it. I only have about 15k on my clutch but looking for something with a little better bite.

        • Yes !!!!! You need to a new flywheel with all spec clutches. The stock one will not work. Their website says "recommended" but that is not true it is 100% required or else it will not fit. The other catch is that spec clutch kits only work with the spec flywheel do not be fooled and make a mistake. Also the v6 spec flywheel is $480 so factor that in your price.

        Has anyone used this with your stock flywheel i know it recommends you use there flywheel but I know someone that used a spec stage 3 on his s550 and it's been fine with his oem flywheel

        Would this clutch have any issue operating with an oem hydraulic Throwout bearing? I’ve read that some clutches have issues with them. Thanks!

        Does this clutch help with the 7k rpm lockout?

        • The Spec Stage 1 Clutch will help, but may not entirely eliminate the 7k lockout. We recommend pairing this with an aftermarket shifter and shifter support to ensure the condition is completely eliminated.

        Why will this not fit a 2015-2017 GT?

        • This clutch is designed for the 11-14 Mustang GT models. Unfortunately fitment has not been tested with the S550 models so we would be unable to confirm fitment.

            Chatters and shakes like crazy

            1st tried the mcleod super street clutch, chattered and shook bad on engagements thought it was the stage 2 disc it came with. Then tried these spec stage 1 with organic disc still chattered and shook really bad on 1st engagements. And yes i did break them in properly 500miles etc. It did chatter a bit less after the break-in period it was still bad enough to make you wait all day just to avoid traffic. Finally bought a whole stock set and she rides like brand new again, zero chatter, smoothest engagements. You learn from mistakes good luck

            I changed everything, clutch, throw out bearing, flywheel and line. Finally the vibration on downshift is GONE!!!!! Definitely worth every penny.

            a good upgrade from stock

            the clutch is good, there is a little chatter at very low rpms, but it is probably from purchasing the single mass aluminum flywheel with this product. overall the clutch pedal is slightly heavier which I liked and it seems to do its job well with abuse.

            Doesn't fit a stock flywheel.

            Had to return didn't fit the stock dual mass fly wheel on my V6. The dowel holes where about 1/4 out of position so screw holes didn't line up. Looked heavier duty then the stock clutch disc.

            SPEC clutch is better than stock

            After 16000 miles of abuse on my 2012 GT clutch it was time to upgrade to a SPEC Clutch. My stock Mustang GT clutch decided to disintegrate after an especially brutal eighth mile run at Lakeland Florida. After barely arriving from the track with a horrific smelling clutch it was time to contact American Muscle. I ordered the SPEC 1 clutch and a steel braded clutch line. The install was fairly straight forward and the quality was evident upon comparison of the stock pressure plate and the SPEC pressure plate. The difference in clutch material is obvious once the two clutches are compared side by side. The SPEC clutch is about twenty five percent wider than the stock one which would prove better at the track once the brake in period is reached. I opted to use the stock flywheel and after having it resurfaced by a local machine shop I noticed that the stock pressure plate has nine flywheel to pressure plate bolt holes while the SPEC pressure plate has six. I modified the pressure plate to accommodate the three additional bolts and all seams fine so far. The clutch is much smother than stock and my notchy transmission is shifting like it should. Thanks American Muscle for another great product.

            Very nice upgrade over the stock clutch and dual mass flywheel!! Pedal effort is just a tad heavier than stock, but not bad at all!! I took my car to the track after the 500 mile break-in period and the clutch performed great launching on M/T ET Street bias ply tires.

            Solid and Subtle Improvement Over Stock

            It is not going to make you walk in circles by making your left legs stronger than Popeye's, but you will get more solid launches. It takes a little more care to make casual starts in slow traffic, but it won't be like a full race clutch.
