  • Ideal Upgrade for Boosted 'Stangs.
  • Good Driveability.

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.

spec stage 2 clutch

I have had this clutch about a year and have not had any problems. It goes perfect of you have a bolt on Gt, like mine. The pressure plate is alittle stiff but it's a performance clutch.

    Stage 2 clutch

    This clutch grabs instantly, decreasing the time in between shifts drastically. It was not harder to press down the clutch pedal, however there is some clatter when car is at idle with the clutch depressed. If you plan on adding power, change your clutch before installing headers, otherwise you will end up having to take off the headers if the clutch has to be changed.

    I installed this clutch in my garage 2 years ago. It chattered during the break in period, which made me wonder if I made the wrong choice going with SPEC. However, after the 450mile break in period was over, the clutch smoothed right out. It has handled my full bolt on GT with a 125/150shot on drag radials without a problem. Its rather smooth when driving. Overall, a good clutch once the break-in is done. I have 26k miles on it now and its been great so far.

    Good Upgrade

    The pedal is softer when pressing in for shifts, whether up or down in gears, and also grabs much easier. For example, when starting up the stock clutch required, I put the pedal to the floor and the replacement engages about 2 inches into the pedal being pushed in. Makes driving a lot more fun. Gave 4 out of 5 because of that weak plastic aligning tool that comes with it.

    Buy SPEC & Roll the Dice

    I had heard good things about SPEC, but I had also heard the horror stories. The good seemed to outweigh the bad so I decided to go with the SPEC Stage 2 & the SPEC Aluminum flywheel. I had the clutch professionally installed by a mechanic I've used for the last 8 years. Right off the bat, this clutch is MUCH louder than stockwith a constant clattering sound. Now, just under 300 miles later, I have a failed TO bearing! Yes, I used the bearing supplied. If you take a chance on a SPEC clutch, at the very least TOSS THE SUPPLIED BEARINGS and get a good quality (ie. FRPP) bearing. As for me, I'm dumping SPEC for a Centerforce.

    TO Bearing alread went out >.

    The clutch itself was pretty nice right when it was put in but about a month later the bearing started getting louder and then 4 months later the bearing was so loud it was unbearable. Time to take this puppy out. I WOULD NOT RECCOMMEND THIS PRODUCT! FYI the clutch was professionally installed and I drive a 03 Mach 1

    Worth It

    The new clutch grabs so much better than the stock clutch. The clutch pedal is much lighter and you can feel exactly where it grabs. Definitely worth it for stock and upgraded mustangs.

    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.

    Great clutch

    Got the Spec stage 2 clutch and spec billet steel flywheel about a year ago. Haven't had any problems so far. I heard complaints about the bearing that came with it so I ordered an OEM ford bearing. The grip is amazing. The clutch and flywheel combo puts every bit of power I have straight to the ground. I would recommend getting it done at a ford dealer however because with a clutch this tight you don't want to make a mistake, also they guarantee their work. I wouldn't go stage three unless you are running FI. All for all my purchase is still worth every penny!! THANKS AMERICAN MUSCLE!!

    Awesome clutch

    I bought the spec stage two clutch about two years ago and had a local shop install for about $300 I also bought the ford racing throw out and pilot bearings I was told to use the ford ones. Two years later and supercharged the whole time never had any problems with the clutch. Love it and would buy it again.

    Replaced everything in the clutch flywheel t/o bearing and it vibrates and shudders worse than any clutch I have ever owned. Wished I hadn't done it. Have to pull it out again then check it over for them. Don't know how long this will keep me without my car.

    Excellent Clutch

    I'm at the end of my break-in period now, but this clutch is amazing so far. The overall feel is smooth, it grabs really well, and I can already feel the better shifts. I'll be racing it soon and I can't wait to see it's true use!

    2001 cobra (spec stage 2)

    I recently had to purchase to a new clutch and heard good things about spec. I ordered the stage 2 and billet flywheel. I had a shop install it and right after I got it back I noticed a bad vibration during acceleration its not horrible but it has been concerning me. I have about 350 miles on it and its still doing it. I heard there is what some call a chatter. I just hope it ends soon but over all I love the new clutch its quit no nose smooth shifts are firm pedal is very nice grabs nice. Everything a clutch should be so a can't complain about the overall feel. Just hope the vibration stops. Thanks a.m. for FAST shipping!

    hole shot!

    This clutch grabs like no other! It has a slight chatter for the first 200 miles or so, but once you break it in its a thing of beauty! My hole shot is awesome with this clutch I jump out on everybody by at least a car and a half! If you want a bang for your buck I would go with this clutch. It has drag strip abilities but you also can go take a weekend drive and be good!

    Good clutch

    Awesome clutch. It costs twice what a oem replacement does but you can feel the difference when you drive it. My stock clutch use to slip going into 3rd strong but this one doesn't it just throws you back in the seat. Only thing I have negative is the throw out bearing that they include sucks bad. and it chatters a little in reverse but you'll have that. Thanks american muscle
