Red Line Heavy ShockProof Gear Oil - 1QT

  • Sale
  • Regular price $31.00

The ShockProof can be used by itself or as a cocktail with other Red Line transmission fluids depending on what application you choose to use it on. 



  • Features a unique lubricant containing a suspension of solid microscopic particles as an extreme pressure agent along with a unique solid dispersion that cushions gear teeth to help prevent tooth breakage which allows the use of lower viscosities
  • Acts like a liquid grease as the viscosity characteristics allow the lubricants to resist throw-off and provide the protection of greater film thickness with a relatively light fluid viscosity which offers the "best of both worlds" balance of low drag and superior protection
  • Works in a variety of differential and transmissions
  • Recommended for heavily-loaded racing differentials and transmissions, and Off-road racing and problem gearboxes
  • Provides a film thickness similar to a 75W250 grade while providing the same low fluid friction as an SAE 75W90 oil
  • Fully-synthetic formula created from polyol ester base stocks, offer excellent lubrication under extreme conditions 
  • Ester base stocks and friction modifiers (except NS) provide additional slipperiness to lower operating temperatures by reducing the sliding friction in hypoid gears
  • High viscosity index (VI) to provide a latively constant viscosity and film thickness with varying temperature change 
  • Superior shear stability and reduced oxidation compared to other synthetics and conventional gear oils 
  • Exceeds GL-5 specifications
  • Engineered to provide the highest degree of protection and improvement of differential efficiency for better mileage, longer drain intervals, and less wear
  • Sold individually in a 1 US-quart container


The Red Line Heavy ShockProof should not be used with pumps, filters, and with small lines as this fluid is designed for wet sump or splash type lubrication
