ACT 4240035 Rigid Race Clutch Disc Ceramic Friction - 4-Pad

The ACT 4240035 is a 4-pad rigid race clutch disc engineered for maximum performance in professional motorsport applications. Built with premium ceramic friction materials, this disc delivers the aggressive engagement and lightning-fast gear changes demanded on the track. Its lightweight rigid construction and heat-treated chromoly hub are purpose-built to handle extreme torque loads and elevated operating temperatures.

The 4-pad puck design reduces rotational mass compared to full-face discs, resulting in faster, more direct shift response. High-grade rivets are carefully selected and precisely positioned to fasten the friction pads with maximum structural integrity, ensuring the disc holds up under the stress of repeated, hard launches. This design is particularly well-suited for smaller disc diameters used in smaller displacement engines.

Key Features:

• Premium ceramic friction material provides moderate wear rates and excellent high-heat tolerance
• Holds 28% more torque than typical organic friction materials
• Heat-treated chromoly hub for superior strength, durability, and resistance to spline wear
• Lightweight rigid design minimizes rotational mass for faster, more aggressive shift response
• Top-grade rivet construction — rivet materials and placement carefully selected for maximum holding strength
• High burst strength rated for the demands of professional racing environments
• Well-suited for smaller disc sizes and smaller-displacement engine applications

Important Notice: ACT race discs deliver aggressive, no-nonsense engagement. Launches from a stop may produce judder or noise — this is normal and does not affect clutch or drivetrain performance. This disc is recommended for professional race use only and is not intended for street use. Increased spline wear is possible with rigid disc designs. ACT recommends an organic disc for all street-driven applications.
