    • you will need to use a GM tensioner part number 12628025 (this is the standard LSA 6 rib tensioner for the Alternator and power steering which bolts to the two main bolt bosses on the left side of the LSA/ZL1 water pump) with a smaller 6 rib pulley to clear the race drive
    • you will need to purchase the LSX-419604


  • Recomended for LSA Supercharged engines making up to 800HP
  • Double shear pulley mounting greatly reducing axle flexing.
  • Provides maximum belt wrap that won't slip at sustained high engine speeds.

  • Rigid belt tension with unique tension setter.
  • Supports both standard deck and tall deck applications including blocks with manifold spacers.
