Customer Favorite Acc Performance Boss Hog 48442 Night Stalker Gm 700r4 Torque Converter Equipment [B2ViwCH4]

ACC Performance designed this Boss Hog 48442 Night Stalker Torque Converter for GM 700R4 transmissions. This hand-built 12” converter has a stall speed of 2200-2800 RPM, and can handle up to 500 horsepower!

All Boss Hog torque converters are welded at the fins, not furnace-brazed, eliminating erosion over time. They include industrial-strength Torrington-type bearings that handle more torque than light-duty needle bearings. Aircraft aluminum washers instead of inferior fiber washers ensure all power transfers directly to the ground.

Boss Hog 48442 Night Stalker Torque Converter Features:

  • Fits GM 700R4 transmissions
  • Stall Speed: 2200-2800 RPM
  • Diameter: 12.00 in.
  • Bolt Circle: 10.750 in.
  • Input Spline Quantity: 30
  • Crank Pilot Diameter: 1.703 in.
  • Mounting Hardware Type: 3/8-16 Bolts
  • Mounting Hardware Included: No
  • Balanced: Yes
  • Transmission Cooler Required: Yes
  • Lockup Compatible: Yes
  • Anti-Ballooning Plate: No
  • Quantity: Sold Individually

Note: Boss Hog recommends a “Street Bandit” series torque converter if you have upgraded intake, headers, exhaust, cam, or gearing. An “Outlaw” series torque converter is highly recommended if you have a Trans Brake, Nitrous Oxide, Turbocharger or Supercharger.
