Feel:
Soft progressive engagement, light pedal effort, smooth shifting with OE to mild transmission gear noise

Lifespan:
The forged aluminum cover, mono-drive hub, exclusive diaphragm, premium friction materials, and hardened wear points guarantee that this long-lasting twin disc clutch performs reliably and endures even the most demanding conditions.

Quality:
Achieves peak performance and high heat resistance through a combination of durable design, strategic features, premium materials, and precise tolerances

Recommended Use:
Street or Street/Strip

Difference between Sprung and Rigid:
When deciding between a sprung or solid hub clutch disc, evaluate their distinct advantages:

• Sprung hub discs include torsional dampeners that reduce driveline shock, extend spline life, and offer quieter operation by minimizing vibrations. For rapid shifting, the four-pad option is best, whereas the six-pad version provides improved heat capacity and smoother engagement.
• In contrast, solid hub discs excel in durability with stronger components. The four-pad design delivers the quickest shifts, while the six-pad option offers a balance of better heat capacity and smoother engagement.

More Info:
T1SS-S01 Mod-Twin 225 HD Sprung Street Kit is designed for high powered AWD street cars. It unites uncompromised pedal feel, durability, engagement quality with very high torque capacity by combining twice the organic friction surfaces with an ultra-durable spring center Mono-Drive hub in a completely modular design. Each diaphragm spring endures an exclusive four-stage heat treating process providing a consistent light pedal feel. Steel-backed Friction Plates with high quality organic friction materials deliver stable friction coefficient, good heat capacity and long clutch life. These Friction Plates uniformly transfer torque to the Mono-Drive sprung hub assembly which extends input shaft life and reduces driveline shock from torsional vibration. This kit includes 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 (if needed). Mod-Twin clutches are fully rebuildable and most components can be ordered separately.
