Alright, gearheads, let’s talk about the Mod-Twin 10.5 HD Sprung Street Kit from ACT. If you’ve got a high-powered street machine, this clutch is going to be your new best friend. It’s built for those who want a solid pedal feel and durability without compromising on performance. The beauty of this kit lies in its dual organic friction surfaces paired with a rugged sprung Mono-Drive hub assembly. It’s modular, which means you can easily swap out parts if you need to—no need to buy a whole new kit every time.
Now, let’s get into the nitty-gritty. Each diaphragm spring goes through a four-stage heat treatment process, so you get a consistent, light pedal feel every time you engage. The steel-backed friction plates are made with high-quality organic materials, giving you a stable friction coefficient and a long clutch life. This setup not only transfers torque smoothly but also extends the life of your input shaft and minimizes driveline shock from torsional vibes. Trust me, your ride will thank you for it.
This kit comes packed with everything you need: a CNC-machined, dynamically balanced flywheel, pressure plate cover, diaphragm spring, puck-style ceramic friction plates, and that nifty Mono-Drive hub assembly. Oh, and let’s not forget the patented Monoloc Collar, release bearing, alignment tool, and pilot bearing (where applicable). The Mod-Twin clutches are also fully rebuildable, so if you ever need to replace a disc, you can grab one separately without breaking the bank.
