Product Details

The B&M Tork Master 2400 is a high-performance torque converter designed for street/strip applications with GM TH400 (1965-1991) and TH350 (1968-1981) transmissions. This converter features a 2400 RPM stall speed that delivers quicker launches and harder acceleration while maintaining decent street manners.

Key Features:

  • 2400 RPM stall speed for improved off-the-line performance
  • Fully balanced and pressure tested for reliability
  • New precision alloy steel pump tube for durability
  • New needle thrust bearing (when factory equipped)
  • Compatible with GM TH400 (1965-1991) and TH350 (1968-1981) transmissions
  • Built with B&M's proven quality and durability standards

This torque converter is ideal for moderately modified engines with increased power output, providing better low-end torque multiplication and more aggressive acceleration compared to stock converters. The Tork Master 2400 strikes a balance between performance and drivability, making it suitable for street-driven vehicles that see occasional strip use.
