Product Details

The McLeod 4953-00-07 Soft Lok is a high-performance clutch assembly engineered for Mopar 340, 383, and 440 cubic inch engines featuring a 6-bolt crankshaft. Sized at 11" x 1-1/8" x 26-spline with a 143-tooth ring gear, this assembly is purpose-built for drag racing applications and is not recommended for street use.

As an NHRA and IHRA record-holding clutch system, the Soft Lok is one of McLeod's most widely used competition clutch assemblies. Its design prioritizes hard, consistent launches with reduced tire spin, making it a proven choice at the drag strip.

Key Features:

  • Low static clamp pressure for a light pedal effort and smooth, soft clutch engagement
  • Adjustable spring pressure allows tuning to match track conditions and driving style
  • Available with counterweights for added balance and consistency
  • 0-balance aluminum flywheel — lightweight and optimized for high-RPM performance
  • Designed to leave the starting line harder with less tire spin
  • Compatible with Mopar 340, 383, and 440 engines with 6-bolt crankshaft flanges
  • Spline spec: 1-1/8" x 26-spline
  • Ring gear tooth count: 143T

What's Included:

  • Pressure plate
  • Sintered iron clutch disc
  • Aluminum flywheel

The McLeod Soft Lok system delivers the adjustability and reliability serious drag racers demand. With decades of proven track performance and championship credentials, this complete clutch assembly is a cornerstone of McLeod's competition lineup.
