Construction & Design:

The ACT Twin Disc MaXX XT Street Kit is meticulously engineered with premium materials to withstand the rigors of high-performance driving. The clutch discs feature a steel-backed lining combined with high-copper organic friction material, optimizing heat dissipation and durability. The chrome-moly hubs are heat-treated to provide exceptional strength, while the rivets are selected for maximum shear resistance, ensuring long-lasting reliability.

ACT’s Positive Lift Floater System eliminates common twin disc issues such as floater rattle and post wear, resulting in a quieter and more durable clutch assembly. The four-stage heat treatment applied to the diaphragms enhances their fatigue resistance, allowing the clutch to maintain consistent clamp load and performance over time.

Performance & Sound

This twin disc clutch kit offers a heavy to very heavy pedal effort with smooth engagement, making it suitable for street-driven vehicles that demand strong holding power and minimal gear rattle. The doubled disc surfaces improve heat capacity, reducing fade during spirited driving or track use. The design also helps moderate gear rattle, contributing to a refined driving experience without sacrificing performance.
