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.

Very good product! Gorgeous wood
These 4’ wide shelves are very nice. The wood is blond and gorgeous. I bought 2 sets. The hardware is very heavy duty iron piping!

Great when installed. Some problems
Style: 48inch 2 tier
The shelves are assembled and installed on my wall. I'm happy with them. They look great and are very sturdy. What prevents a 5-star rating? The instructions were poor. Not a huge deal as I was able to figure things out. The wall anchors that came with were cheap and (in my opinion) unusable. I went to Lowe's and bought some drywall anchors that were rated for 79 pounds and they worked well. During the install, I wasn't sure if I should attach the wall plates and assemble the shelves on the wall, or assemble everything and then attach it to the wall. Assembling before hanging was the way to go but it took two people. One other minor thing: The shelves are stained on one side an not the other. Since I have them high up on a wall, I'm looking at the unstained side. Yes, I can stain the unstained part, but it would be nice if they had just stained the top and bottom at the factory.

Beautiful Shelving Unit
Style: 48 inch 3 tier
The shelving unit is beautiful. It has not been hung yet, but I plan on using it to replace my entertainment center and hang my TV above it. I am so excited as the shelves matched perfectly to my furniture so I believe it will be a lovely addition to my living room and take up less space than the entertainment center does.
