Product Details

The B&M Holeshot 3000 Torque Converter is engineered for high-performance street and strip applications in 1984-1993 GM vehicles equipped with 700R4 or 4L60 transmissions. This torque converter features a 3000 RPM stall speed that delivers aggressive launch characteristics while maintaining drivability for street use.

Key Features:

  • Race-proven design utilizing competition-tested technology and quality construction
  • Precision alloy steel impeller hub for enhanced durability and heat resistance
  • Copper furnace brazed impeller and turbine assembly ensures maximum strength and prevents failure under high stress
  • Precision balanced on certified balance equipment to eliminate vibration and ensure smooth operation
  • 3000 RPM stall speed optimized for engines with moderate camshaft upgrades and performance modifications
  • Direct bolt-in replacement for stock torque converter

The Holeshot 3000 is ideal for enthusiasts running engines with upgraded camshafts, increased compression, or forced induction who need improved off-the-line performance without sacrificing daily drivability. The higher stall speed allows the engine to build boost or reach its powerband before the vehicle launches, resulting in quicker acceleration and improved ET times.
