McLeod 6405504 RST Twin Disc Clutch Kit Steel Flywheel GM LS-X 6-Bolt 168T 1-1/8x10

The McLeod 6405504 RST Twin Disc Clutch Kit is a high-performance, street-focused clutch solution designed for GM LS-X engines with a 6-bolt crankshaft flange. This complete kit pairs a billet steel flywheel (168-tooth ring gear) with McLeod's twin disc clutch assembly, using a 1-1/8" x 10-spline input shaft for a true plug-and-play installation.

The RST series is purpose-built for the high-horsepower street enthusiast, offering a factory-matched, dedicated flywheel and clutch under a single part number — eliminating the need to source components separately. Rated to handle up to 800 horsepower, this kit delivers serious power capacity while maintaining everyday street drivability.

Key Features:

• Rated up to 800 hp — capable of handling extreme street power levels
• Twin disc design for increased torque capacity without sacrificing drivability
• Organic-lined clutch discs provide smooth, progressive engagement and a light pedal feel
