McLeod 6440802 Original Street Twin Clutch Kit Steel Mopar Hemi & Wedge 8-Bolt 1x23 130T

The McLeod 6440802 Original Street Twin is a steel twin-disc clutch kit engineered for high-horsepower Mopar Hemi and Wedge big-block applications using an 8-bolt, 130-tooth flywheel. Designed for serious street performance builds, this kit delivers the holding power needed for power-adder setups — including nitrous, superchargers, and turbochargers — while maintaining the street manners required for daily driving.

McLeod pioneered the street-oriented twin-disc clutch concept, and the Original Street Twin remains the benchmark. The dual-disc steel design dramatically increases clamping force and torque capacity over a single-disc setup, handling up to 1,200 horsepower without sacrificing drivability or pedal feel. The 1-inch by 23-spline input shaft configuration and 130-tooth flywheel compatibility make this a direct-fit solution for classic Mopar 1963–1972 Hemi and Wedge manual transmission applications.

• Twin-disc steel clutch design for maximum torque capacity
• Rated to handle up to 1,200 horsepower
• Compatible with 8-bolt, 130-tooth Mopar flywheels

McLeod Racing backs this kit with their 90-day limited warranty against defects in materials and workmanship. Pressure plate bolts should be torqued per McLeod specifications (3/8" bolts: 35 ft-lbs; 10mm bolts: 45 ft-lbs). A proper break-in period of 500–750 miles of stop-and-go city driving is recommended to maximize clutch life.
