ACT Heavy Duty Performance Street Sprung Clutch Kit for 2003-2006 Nissan 350Z and Infiniti G35 (NZ1-HDSS)

Fits 2003-2006 Nissan 350Z and Infiniti G35 (Base, Enthusiast, Grand Touring, Performance, Touring, Track, and 35th Anniversary Edition).

The ACT NZ1-HDSS clutch kit is engineered for drivers seeking a significant increase in torque capacity without sacrificing street driveability. This kit combines the ACT Heavy Duty pressure plate with a Performance Street sprung disc, providing a firm pedal feel and improved engagement. The pressure plate features an exclusive diaphragm design that increases clamp load while reducing deflection, ensuring consistent performance under high-stress conditions. Every diaphragm undergoes a specialized four-stage heat-treating process for maximum durability.

The Performance Street disc is constructed with premium organic materials containing high copper content to facilitate superior heat transfer. Steel-backed linings increase burst strength, while a reduced marcel design enables faster, more precise gear changes. This kit is an ideal solution for modified street cars requiring a reliable drivetrain upgrade.
