Fitment Notes

• McLeod identifies 6405507MD as an RST HD twin-disc clutch kit with a steel flywheel for 1997-2015 GM LS applications using a 6-bolt crankshaft.
• Designed for compatible manual-transmission GM LS applications using a 1-1/8 x 26-spline transmission input.
• Includes a 168-tooth steel flywheel.
• Automatic-transmission applications are excluded.
• Verify the engine crankshaft bolt pattern and transmission input spline before installation, particularly on engine-swapped or modified vehicles.
• The 6405507MD is a dedicated steel-flywheel configuration and should not be confused with McLeod LS kits using different flywheel materials, spline sizes, or crankshaft configurations.

Features

• McLeod RST HD twin-disc clutch system engineered for high-horsepower street and track use.
• Dual-disc design provides substantially greater friction area than a conventional single-disc clutch.
• Hybrid friction configuration combines smooth-engaging organic material with high-bite segmented ceramic material.
• Organic friction material promotes smoother engagement and street-friendly drivability.
• Segmented ceramic friction material provides increased bite and torque-holding capability.
• Rated by McLeod for applications producing up to 950 hp.
• Steel flywheel provides a durable dedicated mounting surface for the LS 6-bolt crankshaft configuration.
• 168-tooth ring gear matches the specified GM LS flywheel application.
• 1-1/8 x 26-spline hub configuration is designed for compatible GM manual transmissions.
• Designed to balance increased power capacity with manageable street engagement.
• Suitable for performance street vehicles and vehicles that also see track or spirited driving.
• Complete clutch-and-flywheel package eliminates the need to source a separate compatible flywheel.

Product Description

The McLeod 6405507MD RST HD Twin Disc Clutch Kit is a high-performance clutch and flywheel package designed for compatible 1997-2015 GM LS applications using a 6-bolt crankshaft. The kit combines McLeod's RST HD twin-disc clutch with a dedicated 168-tooth steel flywheel and a 1-1/8 x 26-spline configuration for compatible manual transmissions.

The RST HD uses a hybrid friction strategy, pairing smooth-engaging organic material with segmented ceramic friction material. This combination is designed to provide a balance of street drivability and increased torque-holding capability for performance vehicles. McLeod rates the RST HD platform for applications producing up to 950 hp, making it suitable for high-output street builds and vehicles that see occasional track use.

The 6405507MD is applicable to selected manual-transmission Camaro, Corvette, Firebird, and GTO configurations using compatible GM LS engines and the specified 6-bolt crankshaft/flywheel arrangement. Proper installation requires verification of crankshaft bolt pattern, transmission input spline, bellhousing alignment, and clutch compatibility. McLeod recommends replacing the pilot bearing, properly preparing the flywheel, and completing the prescribed clutch break-in procedure after installation.
