  • Out-of-Stock
  • Popular for cars and light trucks like Ford Mustang and F-150, Toyota Tundra and Sequoia, Jeep Cherokee and Dodge Ram
  • 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, since the extreme slipperiness may cause synchronizer mesh issues that lead to shifting problems
  • Recommended for API GL-5, GL-6, MT-1, MIL-L-2105E and SAE J2360
Red Line Oil 75W90 GL-5 GEAR OIL 945ml (1 US quart)
  • Out-of-Stock
  • 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 extreme 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
Red Line Oil HEAVY SHOCKPROOF GEAR OIL 946ml (1 US quart)
  • Out-of-Stock

Film thickness greater than an SAE 75W250, yet low fluid friction like 75W90
For heavily-loaded racing differentials and transmissions, problem gearboxes
Most popular ShockProof product, many racing and specialty applications
Many performance racing applications like Sprint, Midget, Dirt Late Model and Quick Change Differentials, Detroit Lockers and spools, NHRA Top Fuel and Funny Car rear ends
Not recommended for most synchro applications due to the product's extreme slipperiness

Red Line Oil MT-90 75W90 GL-4 GEAR OIL 946ml (1 US quart)
  • Out-of-Stock
  • 75W90 GL-4 gear oil (similar to SAE 5W40/10W40 engine oil viscosity)
  • Popular in Nissan, Mazda, Mitsubishi, VW/Audi, Lotus Elise/Exige, Toyota, Mendeola transmissions and Atlas transfer cases for Off Road
  • Offers quicker shifts, perfect synchronizer coefficient of friction
  • Safe for brass synchros, as it lacks the reactive sulfurs found in most GL-5 oils that cause damage
  • High performance gear protection and longer synchro life
  • Eliminates notchy shifting, even when cold
  • Satisfies the gear oil viscosity requirements of 75W90, 80W90, 90 and motor oil viscosities of SAE 40, 10W40 and 15W40
  • Recommended for GL-1, GL-3 and GL-4 applications, as well as where most special synchromesh fluids are specified
