Description:

The T1SS-F12 Mod-Twin 10.5 HD Sprung Street Kit is tailored for high-powered street machines, offering a blend of uncompromised pedal feel, durability, engagement quality, and high torque capacity. This kit achieves its performance through a modular design that combines twice the organic friction surfaces with an ultra-durable sprung Mono-Drive hub assembly.

Each diaphragm spring undergoes an exclusive four-stage heat-treating process to ensure a consistent light pedal feel. The steel-backed friction plates, featuring high-quality organic friction materials, deliver a stable friction coefficient, good heat capacity, and long clutch life. These friction plates uniformly transfer torque to the Mono-Drive sprung hub assembly, extending input shaft life and reducing driveline shock from torsional vibration.

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

Features:

  • Feel: Soft, progressive engagement, lightest 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 long life and performance under 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: Utilizes tactical engineering to address common tradeoffs found in twin-disc clutches, resulting in an ultra-durable, customer-serviceable, long-lasting clutch with very high torque capacity. All clutches are 100% clamp load tested, balanced, and SFI certified.

Vehicle Fitment:

  • Application: Engine
    • Various Ford Mustang GT models from 2018 to 2023 with 5.0 V8 GAS FI 4951cc engines and DOHC configuration.

Perfect heel!
Size: 11, Color: Gold/Glitter
Love these heels! I bought the gold and wasn’t expecting them to be most glittery. They are beautiful and comfortable! The heel is chunky enough that these walk like a wedge but don’t look like the heels from the lay 90’s. Love them and will be buying in different colors n

Great heels for beginners or comfy shoe girlies
Size: 11, Color: Nude/Clear
I am a sneaker/comfy shoe girlie. I bought these heels because it had so many great reviews. Baby!! They do not disappoint. I am 5’10 230lbs. I bought these in a size 11. This by far is the most comfortable heel I have ever worn. They are great and so comfortable to wear. Usually I bring an extra pair of flats to change into at the end of the night. No need for that with these. They are easy to walk in and they hold my weight. I love that they run a little big, I love that they have little extra space for wiggle room in the back. The only issue I had was they don’t run wide for an 11 so the toe strap was a little tight but it’s nothing a little stretching can’t help with (blow dryer and YouTube videos). Also it’s a quality shoe for a great price. Definitely will buy more in different colors.

Love these!
Size: 9, Color: Champagne-satin
I purchased these to attend a wedding as a guest. I wear a size 9 sneaker and ordered a size 9 in these. They fit well and are fairly comfortable during a quick try on and walk around. Theyre a little slick on the bottom but have a textured sole to help which i love. The color is so pretty and is true to what is pictured. I haven't worn these for an extended period of time, but feel as if they will be fairly comfortable for wedding wear. I love the chunk heel as it provides more support to walk around on. Overall great heel!

Beautiful Shoes, Bring Band-Aids
Size: 8, Color: Gold/Glitter
I bought these for a wedding and, let me tell you, they passed the ultimate test: an entire night of dancing like I was still in my twenties. The shoes are cute, surprisingly sturdy, and looked great with my dress. They made it through hours of standing, walking, and questionable dance-floor decisions. That said... my feet were not thrilled with me afterward. I ended up with blisters that seemed determined to become a permanent part of my personality for the next couple of weeks. Would I wear these as an everyday shoe? Absolutely not. Would I wear them to another wedding? Probably. Were they worth the cost? Definitely. Just do yourself a favor and pack some blister pads in your purse before you hit the dance floor.
