Product Details

The McLeod 6400104 Original Street Twin is a high-performance dual disc clutch kit engineered for high-horsepower street applications. Rated to handle up to 1,200 horsepower, this clutch system delivers the power-handling capability demanded by forced induction and power-adder builds while remaining completely street-friendly in daily driving conditions.

Designed for Chevrolet small block (1955–1985) and big block (1970–1990) engines, this kit is built around a steel flywheel with a 168-tooth ring gear and features a 1-1/8" x 10-spline input shaft configuration. The diaphragm-style pressure plate provides consistent clamping force, while the organic disc facings deliver smooth, predictable engagement with manageable pedal effort — critical for a street-driven vehicle.

Key Features:

  • Horsepower rating: up to 1,200 HP
  • Designed for supercharged, turbocharged, nitrous, and big cubic inch engine applications
  • Steel flywheel included with 168-tooth ring gear
  • Input shaft: 1-1/8" x 10-spline
  • Disc diameter: 10.5"
  • Organic disc material for smooth street engagement
  • Diaphragm-style pressure plate
  • Compatible with Chevrolet SBC (1955–1985) and BBC (1970–1990)
  • Zero balance configuration

The Original Street Twin represents McLeod's benchmark twin disc clutch solution for serious street performance builds that need race-level torque capacity without sacrificing drivability. A proper break-in period of 500–750 miles of stop-and-go driving is recommended to fully seat the discs for optimal performance and longevity.
