The McLeod RXT 1200 HD Twin Disc Clutch Kit (6406607HD) is a complete, modular street/strip clutch system engineered for high-horsepower GM LS applications. Rated to handle 1,200 crank horsepower, this RXT HD unit features a higher clamp load than the standard RXT twin disc, making it the ideal choice for builds that demand serious power transfer without sacrificing daily driveability.

Key Features:

• 1,200 HP rating — higher clamp load than the standard RXT twin disc clutch for maximum power handling
• Dual ceramic-lined clutch discs — provide smooth, progressive engagement with a near-stock pedal feel
• 9.687" (246mm) full-face disc diameter — optimized for GM LS platform torque capacity
• Billet steel flywheel included — 168-tooth ring gear, zero balance, 6-bolt crank pattern, purpose-built for street performance
• 1-1/8" x 26-spline input shaft — compatible with standard GM manual transmission spline specifications
• Modular assembly design — steel base plate acts as the adapter; align 6 dowel pins and 6 bolt holes, secure hardware, and install is complete
• Complete plug-and-play kit — clutch assembly and dedicated flywheel sold together under one part number; no sourcing separate components
• Zero balance flywheel — matched and ready for direct installation without additional balancing

The RXT 1200 HD modular assembly is McLeod's most straightforward twin disc solution for the performance enthusiast who wants street manners and strip capability from a single system.
