Product Details

The McLeod 6300407M Original Street Twin is a high-performance twin disc clutch kit engineered for small block Chevy (SBC) applications from 1986–1999. Rated to handle up to 1,200 horsepower, this clutch system is built for high-horsepower street cars equipped with superchargers, turbochargers, nitrous oxide systems, or large cubic inch engines — all while remaining completely street-drivable.

Born in 1974 when power adders began rising in popularity, McLeod's Original Street Twin was purpose-built to deliver the grip needed for serious power without sacrificing everyday drivability. This kit pairs a twin organic-disc clutch assembly with a dedicated billet aluminum flywheel featuring a 153-tooth ring gear, making it a true bolt-on solution with no need to source a flywheel separately.

Key Features:

  • Rated up to 1,200 HP — ideal for supercharged, turbocharged, nitrous, or big cubic inch builds
  • Includes dedicated billet aluminum flywheel for reduced rotating mass and quicker revs
  • 153-tooth ring gear for correct SBC starter engagement
  • 1-1/8" x 26-spline input shaft specification
  • Twin organic-faced solid hub friction discs for smooth engagement and soft pedal feel
  • Blanchard-ground floater plate with multiple straps to minimize noise for streetability
  • Excellent release characteristics for clean, consistent shifts
  • CNC-machined and anodized components for durability and precision fit
  • Complete kit — pressure plate, two organic friction discs, floater plate, and pilot alignment tool included

The McLeod Original Street Twin delivers a driver-friendly clutch experience suitable for most street performance enthusiasts who demand reliable, high-capacity power transfer without sacrificing daily comfort. This is not intended for competition use with slicks or racing tires — street tires only.
