  • Film thickness greater than an SAE 75W250, yet low fluid friction like 75W90
  • For heavily-loaded racing differentials and transmissions, problem gearboxes
  • Most popular ShockProof product, many racing and specialty applications
  • Many performance racing applications like Sprint, Midget, Dirt Late Model and Quick Change Differentials, Detroit Lockers and spools, NHRA Top Fuel and Funny Car rear ends

Acting like a liquid grease, these unique lubricants contain a suspension of solid microscopic particles as an extreme pressure agent, offering a "best of both worlds" balance of low drag and superior protection for gear teeth

  • Unique lubricant with solid microscopic particles offers low drag/high protection
  • 40% lower coefficient of friction and 250% of the load carrying capacity of conventional gear oils
  • Relatively low viscosity, yet cushions gear teeth under extreme pressure
  • Helps to prevent tooth breakage, resists throw-off
  • Can be used with pumps and coolers when equipped with an inline screen rather than a fine filter. Avoid pumping down the center of a main shaft as the unique particles could centrifuge out of solution.
  • Designed for wet sump transmissions and differentials with splash lubrication
