This SunCoast high stall converter is used primarily for racing or max effort builds. This torque converter launches violently and billet internal parts should be considered when using this due to the extreme torque multiplication. Necks will break and feelings will be hurt.

  • Billet triple disc with billet stator
  • Perfect for race & max effort applications
  • Works best with very large single, compound or triple turbo setups


  • Towing is not recommended with this converter
