The LSA /ZL1 Supercharger Heavy Duty Race Drive design is specifically for the LSA/ZL1 supercharged engines used in extreme applications. The unique Race Drive pulley positions are optimized to provide extreme belt wrap to avoid slippage under heavy loads during racing and extreme usage.

Installation Requirements:

  • On engines using our high mount A/C kit
    • if you already own one of our high mount A/C kits you will need to verify you have a 70MM (2.750) Smooth Tensioner Pulley. Older kits used a 76MM pulley and has since been replaced with the now standard 70MM pulley
    • If your A/C kit does not have the 70MM smooth pulley you will need to purchase part number LSX-RD89052
  • On engines not running our high mount A/C 
    • 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
    • Compatible with No A/C and Low Mount A/C

Features:

  • Double shear pulley mounting greatly reducing axle flexing.
  • Provides maximum belt wrap that won't slip at sustained high engine speeds.
  • Supports virtually any know upper and lower overdrive pulley used individually or in combination. It allows up to a 10 inch lower crank pulley and any overdrive upper pulley (stock 3", 2.85", 2.55", 2.38", etc...)
  • Rigid belt tension with unique tension setter.
  • Supports both standard deck and tall deck applications including blocks with manifold spacers.
