If you're serious about your ride and need a clutch that can handle the power without sacrificing feel, the Mod-Twin 10.5 HD Sprung Street Kit is worth a look. This isn't just any clutch; it's built for high-powered street machines that demand more than the average setup. With dual organic friction surfaces, it delivers a solid engagement and a pedal feel that won't wear you out during those long drives.
What's cool about this kit is the Mono-Drive hub assembly. It's designed to take a beating, yet it keeps things smooth. The diaphragm spring goes through a four-stage heat treatment process, ensuring that light pedal feel you want, even when you're pushing the limits. Plus, the steel-backed friction plates are made from high-quality organic materials, giving you long-lasting durability and a stable friction coefficient. It’s all about transferring torque efficiently to the hub assembly, which helps extend the life of your input shaft and reduces those annoying driveline shocks.
When you open the box, you’ll find everything you need: a CNC-machined and dynamically balanced flywheel, pressure plate cover, diaphragm spring, puck-style ceramic friction plates, and even an alignment tool. It's like they thought of everything to make your install smoother. And if you ever need to refresh it, the Mod-Twin is fully rebuildable, so you can just grab replacement discs without having to replace the whole kit.
