These products contain the extreme pressure additives necessary for ultimate protection road cars and racing vehicles, as well as friction modifiers for proper limited-slip operation Fully-synthetic formulas created from polyol ester base stocks, offer excellent lubrication under extreme conditions. High viscosity-index (VI) to provide relatively constant viscosity and film thickness with varying temperature change. Ester base stocks and friction modifiers provide additional slipperiness to lower operating temperatures by reducing the sliding friction in hypoid gears Details: Sold as 1 Quart Superior shear stability and reduced oxidation compared to other synthetics and conventional gear oils Exceed 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 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 Popular Applications: BMW 2002-present with Limited Slip (M series) Chevrolet/GMC 1993-2000 3500HD with Dana 80 Dodge 2003-2006 Ram Pickup 2003-2004 Dakota, Durango with trailer towing package 2005-2009 Dakota, Durango, Aspen rear differential 2008-2009 1500, 2500, 3500 C200FE front differentials, all corporate rear axles Ford 2001- 2004 Mustang Cobra 2002-present Mustangs 2002-2006 Lincoln LS 1999-2006 Lincoln LS (Sport) 1998-2000 5-liter Explorer 1998-present Explorer, Expedition, F-150, E250, E-350 1999-2004 F-250 1998-2006 E-150 Nissan 04-Frontier, XTerra M226 rear differential 2004-2008 Titan rear differential Jeep 1993- 2007 Cherokee, Grand Cherokee, Grand Wagoneer, Wrangler Class III or Class IV hitch, towing package Grand Cherokee with Vari-Lock or Quadra Drive 2008-present Commander and Grand Cherokee all differentials 2005-2006 Rubicon with 226 rear differential 2002-2003 Liberty Front and 02 - 07 198RBI rear differential, 08 - 8 1/4 rear differential 2007-present Nitro 8 1/4 Jaguar 2000-present S-Type, X-Type 2007-XK series 2004-2007 XJ8, XJR 2008-present All Vehicles Toyota 2004-present Tundra without Limited Slip 2002 on Sequoia API Service Class GL 5 Plus SAE Viscosity Grade (Gear Oil) 75W140 Vis at 100 degrees C, CSt 27.8 Vis at 4 degrees C, CSt 192 Viscosity Index 183 Pour Point, degrees C neg 45 Pour Point, degrees F neg 49 Brookfield Viscosity, Poise 1300 at neg 40 degrees C
