Product Description

The SPEC Clutch SN543 Stage 3 kit is engineered for vehicles where the factory clutch can no longer reliably handle upgraded power, hard launches, or sustained high-RPM driving. This kit delivers significantly increased holding capacity and heat resistance compared to stock or lower stage kits, while maintaining a usable engagement for street use. Ideal for drivers of the Nissan 240SX (2.4L KA), 280Z/ZX or early Maxima builds who are pushing their drivetrain seriously.

Installation is direct for the listed fitment vehicles when matched with proper flywheel, release bearing and transmission interface. Because this is a high-performance clutch system, ensure your driveline components (flywheel, release mechanism, pilot bearing and transmission input shaft) are in good condition and match the spline count before installation. For daily-driven performance builds or track use, this SN543 kit offers a balance of durability, engagement, and power capability.
