Description:

The T1S-S01 Mod-Twin 225 HD Rigid Street Kit offers easy pedal feel, smooth but positive engagement, and quick shifting for high-powered AWD vehicles. It achieves this by combining twice the organic friction surfaces with a no-nonsense rigid Mono-Drive hub in a modular design.

Each diaphragm spring undergoes an exclusive four-stage heat-treating process. Steel-backed Friction Plates with high-quality organic friction materials deliver a stable friction coefficient, good heat capacity, and long clutch life. These Friction Plates uniformly transfer torque to a Mono-Drive chrome-moly hub, which is heat-treated for strength and durability, extending input shaft life with one continuous spline.

The lightweight, rigid design allows for quicker shifts and trouble-free service. The kit includes a CNC-machined and dynamically balanced flywheel, pressure plate cover, diaphragm spring, face, puck-style ceramic friction plates, rigid Mono-Drive hub, 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.

Features:

• Feel: Soft progressive engagement, light pedal effort, quick shifting, with mild to moderate transmission gear noise.
• Life: Forged Aluminum Cover, Mono-drive hub, exclusive diaphragm, premium friction materials, and hardened wear points ensure long-life 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.
