Royal Purple Max Gear Lube 75W90 1Qt


Max Gear is recommended by Starklite Cycle for our Chief Four Speed Overdrive Transmissions. Protect your factory warranty by using the correct oil in your transmission.

Max Gear is a high performance automotive gear oil designed to provide maximum protection to heavily loaded gears while increasing power throughput through the drive
train. Max Gear virtually eliminates both gear and bearing wear—even under severe squeeze film conditions caused by extremely high loads, sudden shock loads or low RPMs. Slippery, synthetic molecules not only reduce wear and friction but significantly increase Max Gear’s cold weather fluidity and lubricity, making it the ideal choice for vehicles operating in cold climates. Gears run smoother, quieter, cooler and longer without overhauls. It is noncorrosive to both ferrous and nonferrous metals.


  • Maximizes horsepower
  • Extends gear and bearing life
  • Reduces operating temperature
  • Lower coefficient of friction
  • Superior corrosion protection
  • Separates rapidly from water
  • Contains limited-slip friction modifier

This is our recommened gear lube for the Four Speed Overdrive Transmission.

Add a quart of this to your transmission to comply with warranty requirements.
