Description:

The T3SS-F12 Mod-Twin 10.5 XX Sprung Street Kit from ACT is engineered for high-powered street machines, offering uncompromised pedal feel, durability, and engagement quality along with very high torque capacity. This kit combines twice the organic friction surfaces with an ultra-durable sprung Mono-Drive hub assembly in a modular design. Each diaphragm spring undergoes an exclusive four-stage heat treating process to ensure a consistent light pedal feel. Steel-backed Friction Plates with high-quality organic friction materials deliver stable friction coefficient, good heat capacity, and long clutch life. The Mono-Drive sprung hub assembly extends input shaft life and reduces driveline shock from torsional vibration.

This kit includes a CNC-machined and dynamically balanced flywheel, pressure plate cover, diaphragm spring, face, puck-style ceramic friction plates, sprung Mono-Drive hub assembly, floater, release bearing, alignment tool, and pilot bearing (where applicable). Mod-Twin clutches are fully rebuildable, and replacement discs may be ordered separately.

Description:

  • Feel: Soft, progressive engagement, increased pedal effort, smooth shifting with OE to mild transmission gear noise
  • Life: Forged Aluminum Cover, Mono-drive hub, exclusive diaphragm, and premium friction materials ensure this long-life twin performs and survives under the most demanding conditions
  • Quality: Delivers maximum performance and high heat tolerance by combining robust design, strategic features, choice materials, and close tolerances
  • Recommended Use: Street or Street/Strip
  • ACT Difference: Applying tactical engineering to the Mod-Twin, ACT presents unique solutions to common tradeoffs found on twin-disc clutches, resulting in an ultra-durable, customer serviceable, long-lasting clutch with very high torque capacity. All are 100% clamp load tested, balanced, and SFI certified

Vehicle Fitment:

This clutch kit is compatible with various Ford Mustang models from 2018 to 2023 with 5.0 V8 GAS FI 4951cc DOHC engines.

A Must-Have Emergency Kit for Every Vehicle, Especially ATVs!
I recently bought this 54PCS Flat Tire Repair Kit with Air Compressor, and I’m seriously impressed. It’s one of those products you hope you won’t need—but are SO glad to have when the time comes. I used it on my ATV after catching a sharp rock on the trail, and it saved the day. The plug worked perfectly, and the air compressor had my tire reinflated in just a few minutes. What I really love is how complete the kit is. From cars and motorcycles to trucks and tractors, it’s got everything you need to handle a flat. The tools are solid and durable, and the case keeps everything neatly organized. It’s compact enough to toss in the back of my truck or ATV storage box without taking up too much space. If you ride ATVs in remote areas like I do, this kit is a no-brainer. It gives you peace of mind and saves you from having to hike back to civilization. Highly recommended!

Kept it in my trunk for months — used it once and it saved me
I’ve had this AUTOWN tire repair kit sitting in the trunk for several months as a “just in case” thing. I have only had to use it once, but the tools and compressor held up and it actually helped me get out of a bad spot where I didn’t have a spare tire available. Just to be clear, I wouldn’t call this a permanent fix. It’s more of an emergency repair to get you back on the road. In my case it did exactly that. Afterward, I went to a nearby tire shop and had the tire repaired the right way. Overall, I’m really glad I had it in the car. Just using it once has already paid for itself.

Saves time and money
Size: 47pcs, Size: 47pcs
I used this kit to fix a flat tire on one of my lawn tractors from a roofing nail. I used the smallest size (blue vial) and the supplied Phillips screwdriver to screw it in after applying a dab of rubber adhesive. Then I waited about 30 minutes to inflate the tire. The only thing missing from this kit is a set of pliers to pull out any nails or screws, so provide your own if you will be carrying this in your vehicle for roadside use. There are three sizes of screws, and they are steel (I expected that they would be plastic or rubber). The steel will have increased durability. The blue vials contain the smallest screws, the pink contain the medium, and the white contain the largest screws. The screws have some sort of pre-applied rubbery stuff on the threads that I believe helps them stick to the rubber with the supplied rubber adhesive. This kit is easy to use and is a great value for the amount of flat tires you can fix on your own versus the work, time, and money it takes to go to a tire shop. The black look of the screws camouflages the repair, just make sure you screw in the plug far enough into the tire that it won't contact the road or it will eventually wear off the black finish.

Tiny Tire Saver Kit
Size: 47pcs
I really like this 47 piece tire repair kit, it feels solid in my hand and the pieces aren’t flimsy at all. The rubber nails are a good size, not too bulky, and the whole set is lightweight enough to keep in the car without adding clutter. The black color looks clean and professional, and the glue works faster than I expected. For the cost, it feels like a smart buy because you get a lot of pieces and it can handle car, truck, or even motorcycle tires. It gave me peace of mind knowing I can fix a flat quickly on my own.
