Red Line LightWeight ShockProof is the intermediate viscosity in the ShockProof range, delivering a film thicker than an SAE 75W140 while flowing more like an 80W gear oil or a 30W motor oil. This is the one-gallon jug, a convenient size for a full service on one vehicle. Sold as a case of 4 one-gallon jugs.

Key Features

  • Film thickness greater than an SAE 75W140, with fluid friction like an 80W gear oil or 30W motor oil
  • Excellent low-temperature flow for improved cold shifting
  • For racing differentials under moderate loads
  • Popular in racing transmissions such as Hewland and other road racing dog-ring boxes
  • Not recommended for most synchro applications due to the extreme slipperiness
  • Suspended solid additive delivers film thickness well beyond what the fluid viscosity suggests
  • Synthetic base stock with excellent shear and oxidation stability
  • Blendable with other Red Line ShockProof grades to reach an intermediate viscosity

Applications

Racing transmissions and moderately loaded racing differentials. Red Line lists it in Hewland and other road racing dog-ring boxes, Bert and Brinn stock car transmissions, and G-Force and Liberty clutchless drag racing boxes.
