Lucas Oil SAE 75w-140 Synthetic Gear Oil is a non-foaming, super slick, long lasting lubricant designed especially for heavy duty or high performance applications where regular gear lubricants just aren't good enough.

Contains a special additive package that cushions gears and resists "squeezing out" under extreme pressure situations where other gear lubricants just aren't good enough. Specially designed to stand up to high temperatures without losing its lubricity.

Excellent for use in limited slip differentials.

  • Heavy duty
  • High performance
  • Stands up to high performance
  • Cools and quiets

Lubrication Engineers SAE 140 Weight Gear Oil, 1 Gallon
                        

Whether you're running a stock flattie and rearend or hopped-up overhead and quick change, you need to run a good gear lube. Remember that your rearend was designed fifty plus years ago and needs all the help it can get. The biggest improvement you can give it is a lubricant that will allow the gears to survive the highway speeds that cars see today. L.E. gear oil is what we use in our 350 mph streamliner, that uses a V-8 quick change, without failure. The "red stuff" provides superior lubrication for long gear life. You can't win if you don't finish. We suggest 90 weight for the street and 140 weight for extreme uses.

  • Formulated using blends of high quality paraffinic and synthetic base fluids
  • Contains a highly shear stable tackiness
  • Unique blend of base fluids and thermally stable EP additives
  • Separates readily from water
  • Contains non-silicone defoaming additives
  • Contains no solids
  • Contains DUOLEC LE's proprietary dual acting liquid wear-reducing and extreme pressure additive
