Product Description

The ACT NZ1-HDG6 Heavy Duty Race Sprung 6-Pad Clutch Kit is a direct-fit performance clutch solution engineered for the 2003-2006 Nissan 350Z and Infiniti G35 equipped with the 3.5 L VQ35 V6 and manual transmission. Designed around ACT's Heavy Duty diaphragm pressure plate and a 6-pad spring-centered ceramic clutch disc, this kit increases clamp load and torque capacity significantly (~580 ft-lbs, ~59 % over stock), making it suitable for high-horsepower street builds, occasional track use, and aggressive driving applications.

The 6-pad race-sprung disc uses high-performance ceramic friction material to withstand elevated temperatures and resist slip under hard acceleration. Its spring-center hub helps absorb torsional vibrations for more predictable engagement, while the carefully engineered pressure plate and balanced assembly offer a blend of performance and reliability. This kit includes essential components such as the release bearing, pilot bushing, and alignment tool for easier installation, though a compatible flywheel must be purchased separately.
