Product Details

The McLeod Street Twin is a high-performance dual disc clutch assembly engineered for drivers who demand serious power handling without sacrificing everyday street drivability. Designed to handle up to 1,200 horsepower, the Street Twin is purpose-built for vehicles equipped with power adders such as nitrous oxide, superchargers, and turbochargers — delivering the reliability and clamping force needed for forced induction and high-output applications.

Unlike single-disc performance clutches that often compromise pedal feel for grip, the Street Twin's dual disc design distributes clamping load across two friction surfaces, resulting in a clutch that engages smoothly and is comfortable for daily driving while still holding up under extreme power demands.

Key Features:

  • Dual disc (Street Twin) design supports up to 1,200 horsepower
  • Street-friendly engagement for comfortable daily driving
  • Compatible with Mopar 1964–2003 340 / 383 / 440 engines with 6-bolt crankshaft
  • Steel flywheel construction for durability and consistent heat management
  • 1 x 23-spline input shaft compatibility
  • 143-tooth ring gear for proper starter engagement
  • Ideal for use with nitrous, supercharged, and turbocharged builds

The McLeod Street Twin is the proven choice for Mopar performance enthusiasts looking to upgrade their clutch system for high-horsepower street and strip applications. This kit includes everything needed for a complete clutch assembly replacement on qualifying Mopar applications.
