Features & Product Details

RallySport Direct is proud to bring you some of the best lubricants in the industry brought to you by Red Line. 

 

This is the Red Line 75W90NS GL-5 Gear Oil. This is a fully-synthetic GL-5-type gear oil that contains the extreme pressure additives necessary for the ultimate in protection for road cars and racing vehicles, as well as friction modifiers (except NS) for proper limited-slip operation. 

 

FEATURES:

  • Most popular Red Line gear oil with thousands of applications for passenger cars, light trucks, and racing vehicles
  • Contains additional friction modifiers for suitability with clutch-type limited-slip differentials for most LSDs, no additional friction modifiers are required
  • This product is not designed for use in most manual transmissions or transaxles in passenger vehicles, since the slipperiness may cause synchronizer mesh issues that lead to shifting problems
  • Recommended for API GL-5, GL-6, MT-1, MIL-L-2105E, SAE J2360, and Chrysler spec MS-9763
  • Suitable replacement for a differential calling for an 80W90 or SAE 90 gear oil
  •  

     

    DETAILS:

  • Fully-synthetic formulas created from polyol ester-based stocks that 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 relatively constant viscosity and film thickness with varying temperature change 
  • Superior shear stability and reduced oxidation compared to other synthetics and conventional gear oils 
  • Exceeds API 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

    5out of 5stars

    This fluid works great in my 2002 wrx. Don't listen to the people reviewing this who put this i there sti rear dif. The STI has clutches that Wes doesn't so the STI requires a different type of fluid

    Not too sure. 9 years ago
    1out of 5stars

    I recently changed the fluid in the rear differential on my 2006 sti from the OEM fluid to this Redline 75w90 fluid. Initially there seemed to be no difference, but after 4 or 5 days I began to hear a metal on metal sound coming from the rear differential. After 7 days I couldn't stand the sound any longer, so I replaced the fluid with OEM fluid from the dealership. I don't know if the fluid hurt my LSD, but just to be safe I will keep the fluid OEM.

    • Q: is it ok for my diff  wrxridehawaii9 years ago

      Hi is this gear oil going to be ok in my Diff(04wrx)? or am i going to have problems like the guy with the 06 sti and his diff?
      • 1 of 1 people found the following answer helpful

        A:  yeah this should work great, the WRX uses a viscous LSD where the STi uses a mechanical unit. While I have never seen any problems in an STi differential, I have used this personally in several of my WRX rear diffs and I love it. Thanks. :)
