McLeod 6405807HD RXT 1200 Twin Disc Clutch Kit with Steel Flywheel GM LS-X 8-Bolt 1-1/8 x 26 Spline 168T

The McLeod RXT 1200 Twin Disc Clutch Kit (PN: 6405807HD) is a high-performance street/strip clutch system engineered for GM LS-X engines with an 8-bolt crankshaft flange. Rated to handle up to 1,200 horsepower, this complete kit pairs McLeod's proven RXT 1200 twin disc clutch assembly with a dedicated billet steel flywheel — making it the ideal choice for serious street and drag strip applications.

Key Features:

• 1,200 HP Power Rating — higher clamp load pressure plate compared to the standard RXT twin disc for maximum holding power
• Twin Ceramic Friction Discs — ceramic-lined full-face sprung hub discs deliver smooth engagement and excellent release characteristics with a moderate pedal effort
• Billet Steel Flywheel Included — dedicated 168-tooth steel flywheel matched to GM LS-X 8-bolt crankshaft flange; no separate flywheel sourcing required
• 1-1/8 x 26 Spline Input Shaft — compatible with standard GM manual transmission input shaft specifications
• Complete Plug-and-Play Kit — includes pressure plate, two ceramic friction discs, floater plate, steel flywheel, and pilot tool
• Patented Adapter Ring Design — McLeod Racing exclusive engineering for precise fitment and added strength
• Street-Friendly Performance — designed to be driven daily while delivering race-ready holding power when you need it
• 90-Day Limited Warranty — backed by McLeod Racing's standard warranty against defects in materials and workmanship

The RXT 1200 is built for the enthusiast who demands the best of both worlds — a clutch that can handle extreme power levels on the track and still provide the drivability needed for street use. The ceramic disc construction provides smooth, predictable engagement without the harsh on/off feel typical of race-only clutches. With everything included under a single part number, installation is straightforward with no need to source components separately.

Kit Includes: Pressure plate, (2) ceramic friction discs, floater plate, billet steel flywheel (168T, 8-bolt), and pilot tool.
