DETAILS

The Mod-Twin 225 HD Rigid Race Kit is engineered for high-powered AWD applications requiring aggressive launches and rapid shifting. This modular twin-disc design combines twice the ceramic friction surfaces with a solid Mono-Drive hub for maximum durability. The diaphragm spring undergoes a four-stage heat treatment for consistent, light pedal feel. Puck-style ceramic friction plates provide superior heat capacity, high friction coefficient, and long life. Torque is uniformly transferred through the chrome-moly Mono-Drive hub, heat treated for strength and extended input shaft life. The lightweight, rigid design ensures quick, precise shifts and trouble-free service. Includes CNC-machined, dynamically balanced flywheel, pressure plate, diaphragm spring, friction plates, rigid Mono-Drive hub, floater, Monoloc collar, release bearing, alignment tool, and pilot bearing (if required). Most components are rebuildable and available separately.

Which Clutch Kit is Right for Me: HD or XT? 

The choice between an HD (Heavy Duty) and XT (Xtreme Duty) clutch depends on your power level and driving style. The HD clutch is ideal for daily drivers and street-focused builds, offering a 20-50% increase in clamping force while maintaining smooth engagement and drivability. It is best suited for vehicles with mild to moderate performance upgrades that see a mix of city driving and occasional track use. On the other hand, the XT clutch is designed for high-performance applications, providing up to a 150% increase in clamping force with a more aggressive engagement. This makes it the preferred choice for heavily modified vehicles, track-focused builds, and those requiring maximum durability and grip. If you prioritize comfort and versatility, the HD clutch is the better option, while the XT clutch is the right choice for extreme performance and aggressive driving.

What’s the Difference Between a Full-Face Disc and a Pucked Clutch? 

Choosing between a full-face organic disc and a pucked cerametallic disc depends on your driving habits and performance needs. A full-face organic disc is best suited for daily driving and mild performance upgrades, offering smooth engagement, longevity, and quiet operation, making it ideal for street-focused vehicles with basic modifications. In contrast, a pucked cerametallic disc is designed for high-performance applications, featuring quick engagement, superior heat resistance, and higher torque capacity. This makes it the go-to option for racing, drifting, and vehicles with significant power upgrades. If you prioritize comfort and seamless engagement for daily use, the full-face organic disc is the right choice. However, if you need rapid engagement and superior performance under extreme conditions, a pucked clutch is the better option.

When Should I Choose a Single Disc Over a Twin Disc Clutch? 

The decision between a single disc and twin disc clutch depends on your vehicle’s power level and intended use. A single disc clutch is best for daily drivers and vehicles with moderate performance upgrades, handling up to 400-600 FT-LB of torque. It provides smooth engagement, an OEM-like pedal feel, and cost-effective performance, making it a great choice for street use with bolt-on modifications like intakes, exhausts, and tuning. Conversely, a twin disc clutch is ideal for high-performance builds exceeding 600 FT-LB of torque, offering superior heat dissipation, higher torque capacity, and faster shifts. This makes it the preferred option for competitive motorsports, aggressive driving, and vehicles requiring extreme torque handling. If you want a balance of affordability and daily drivability, a single disc clutch is the way to go, whereas a twin disc clutch is essential for high-power builds and track-ready performance.

How Do I Decide Between a Prolite and Streetlite Flywheel? 

The choice between a Prolite and Streetlite flywheel depends on your driving style and vehicle modifications. The Streetlite flywheel is designed for daily drivers and street builds, featuring slightly more mass to improve drivability, smooth engagement, and better heat dissipation. This makes it a great option for vehicles that see a mix of city driving and occasional track days. In contrast, the Prolite flywheel is engineered for racing and aggressive performance, offering a lightweight design that reduces mass for quicker revs, sharper throttle response, and faster shifts. This makes it ideal for high-horsepower or lightweight builds focused on track performance. If you need a flywheel that balances comfort and performance for versatile driving, the Streetlite flywheel is the better choice. However, if you prioritize ultimate responsiveness and fast acceleration, the Prolite flywheel is the superior option.
