Bel-Ray® Big Twin Transmission Oil is a multi-grade transmission oil formulated for sliding contacts of spiral bevel gears in differentials and shaft drive transmissions. It provides superior anti-wear, added power, smooth shifting and gear protection. 

Big Twin Transmission Oil is ideally suited for the high pressure and shearing forces unique to Big Twin transmissions. Its distinct red color makes leaks easy to identify in multiple lubrication cavity engines. Premium shear stable, high Viscosity Index base oils prevent lubricant viscosity breakdown caused by heat and sliding/shearing actions of gears. 

  • Superior lubricity minimizes friction for maximum power
  • Resists viscosity breakdown caused by gear shearing action
  • Superior oxidation protection prevents thermal oil degradation for extended performance
