Our Toyota 1979-95 gear drive transfer case output shaft is the only RF1A shaft to feature 30-splines. It features an 52.3% larger cross section compared to the stock output, and it is made from super strong heat treated Chromoly steel. The increased spline count helps spread the load through our 135% thicker "4-30" HD flange. Additionally, our output shaft retains the factory oil pump so daily drivers can take part in the torque fest and we include an oversized version of our world famous EcoSeal rear output seal to keep your rig and the environment clean.

  • 30-Spline Heat Treated Chromoly Output Shaft

  • "4-30" 30-Spline 4-Pattern Heavy Duty Drive Flange
  • Oversized Japanese Nachi Output Bearing

  • Retains Oil Pump for Reliability and Longevity
