When looking for a new clutch, trust Spec for the best in value and performance. All SPEC clutches are SFI approved for racing safety and come with a 120 day warranty from the date of purchase against material and manufacturing defects.

Full details of each clutch stage is at the bottom of this description. 

Note: These clutches will also work in swap applications utilizing Ford 2.3 Turbo engines from Thunderbird Turbo Coupe/Cougar XR-4, Merkur XR4Ti, Turbo GT, or SVO's and T5 transmissions. These are 9" clutch discs so they are also not a direct swap for those using non-turbo flywheels and an 8.5" clutch.  
If using a Merkur T9 transmission or Ranger M5OD trans, this clutch will not work. See our Merkur/Ranger clutch listings for those applications. 

Low Price Guarantee: We'll beat anyone's advertised price for the same part number so if you find a lower advertised price, send us an email with the link to the price and the product you're wanting and we'll provide you with a method to purchase it at a better price. 

Torque Capacity is rated at the flywheel, not at the wheels. If you hope to make 500 lb/ft of torque at the wheels for example, remember to add 15% for a manual trans and 20% for an auto trans to get you in the ballpark of your flywheel torque. If you want prioritize superior street manners relative to the holding power, the 2+ and 3+ are the way to go.

Includes:

  • Pressure Plate
  • Clutch Disc
  • Throwout Bearing
  • Pilot Bearing
  • Spline Alignment Tool

Options/Upgrades:

10 Spline Disc Hub - Stock T5's use a 10 spline input shaft so for those swapping in a T5 from a Thunderbird , 2.3 Mustang, or SVO, select this option.

Stage 1
Types of Driving:
Street, Drag, Drift, Road Race, Rally, Pulling, Autocross
Features an integrally molded carbon kevlar-based, high performance organic lining that offers smooth engagement and excellent life. This lining has an integrally bonded steel backing for strength under high clamp loads and temperatures. The hub is double sprung with spring cover relieves for flexibility and heat treated components for strength and durability. Best for daily drivers and street as it offers a stock type feel with more holding power. Can handle concessional track/off-road use as long as power output is below rated max.

  • High clamp pressure plate
  • Steel-backed and multi-compound woven organic material
  • High torque sprung hub and disc assembly

Stage 2
Types of Driving:
Street, Drag, Pulling, Autocross
Features segmented or full faced pure Kevlar disc with steel backing. This lining features excellent drivability like the stage 1, but offers slightly longer life and higher torque capacity. The hub is double sprung with spring cover relieves for flexibility and heat treated components for strength and durability. If you are planning on a low boost forced induction setup or already have one in yourvehicle, 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 significantly more torque than stock 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 Mustangs that see a lot of time on the street as well as the strip and track.Best for street, drag, pulling and autocross.

  • High clamp pressure plate
  • Pure Kevlar friction material
  • High torque sprung hub and disc assembly

Stage 2+
Types of Driving:
Street, Drag, Autocross, Road Race, Pulling, Rally, Drift
Features a multi-friction disc in a full faced configuration with carbon graphite on one side and Kevlar on the other. Bridging the gap between stage 2 and stage 3, the 2+ offers durability, drivability, and engagement quality characteristic of the stage 2, but with a 15-20% higher torque capacity that's similar to the stage 3. So it's more street friendly than the stage 3 while also lasting longer in street use, but with a bit less holding power. Its twin spring high-torque hub is designed to minimize vibrations, for lesser wear along with heat treated components for strength and durability. Great for street, drag, autocross, road racing, pulling, rally and drift.

  • High clamp pressure plate
  • Hybrid Kevlar and Carbon-Graphite Friction material
  • High torque sprung hub and disc assembly

Stage 3
Types of Driving:
Street, Drag, Road Race, Pulling, Rally, Drift
Features a carbon semi-metallic 6 puck sprung hub disc that has been the leading puck clutch in drivability, life and torque capacity. This unit is designed for street and race cars that require an aggressive but streetable engagement and high torque capacity. Highly modified boosted applications that still see regular street use are a good fit. The hub is double sprung with spring cover relieves for flexibility and heat treated components for strength and durability. Also available in 3 puck configuration. Great for street, drag, road racing, pulling, rallye and drift.

  • High clamp pressure plate
  • Carbon-Graphite Friction Material
  • High torque sprung hub and disc assembly

Stage 3+
Types of Driving:
Street, Drag, Autocross, Road Race, Pulling, Rally, Drift
The flagship stage for a high powered street or race car that requires a manageable and friendly engagement, the stage 3+ features a carbon semi-metallic full faced material that offers unparalleled life, friction co-efficient and drivability characteristics in one single package. It bridges the gap between the stage 3, 4, and 5 clutches, having some of the best characteristics of each, and combining them into one durable, high clamping power, race friendly clutch. Highly modified high boost applications that still want the best street manners possible are a great match to this clutch. The hub is double sprung with spring cover relieves for flexibility and heat treated components for strength and durability. Great for street, drag, drift, autocross, road racing, pulling, rally and drift.

  • High clamp pressure plate
  • Carbon Semi-Metallic Friction Material
  • High torque sprung hub and disc assembly

Stage 4
Types of Driving:
Drag, Road Race, Pulling, Rally, Drift
This unit is a solid hub version of the stage 3. The hub is solid 8-rivet and the assembly is heat treated for strength and durability. It is available in a 3, 4 or 6 puck configuration depending on the application. Specially designed as an ideal solution for racing applications. It features a solid hub to provide excellent strength and durability while the 6-puck configuration ensures the smoothest engagement. However, as a racing clutch, this is not street-friendly due to its extreme rigidity. Street drivable in 6 puck configuration, but not street friendly due to the rigid hub. This is as close as you can get to a full race clutch while still having some semblance of street ability. Best for drag racing, road racing, pulling, rally and drift.

  • High clamp pressure plate
  • Carbon-Graphite Friction Material
  • High torque solid hub and disc assembly

Stage 5
Types of Driving:

Extreme Street, Drag
Features a full-metallic disc with the highest possible friction co-efficient. Street drivable if you're hardcore but not street-friendly. Designed for maximum holding power first and foremost. Street type driving that requires slipping the clutch will wear out the disc, flywheel, and pressure plate more quickly than any of the other stages above. It is made to grab to it doesn't like to be slipped. The hub is solid 12-rivet and the assembly is heat treated for strength and durability. Best for extreme street and drag racing.

  • High clamp pressure plate
  • Full-metallic friction material
  • High torque solid hub and disc assembly
