Redline BMW Drivetrain Parts for BMW E90 M3 S65 4.0L

Clear BMW chassis

Please ensure your correct model is selected

Building your perfect BMW is more than just adding horsepower and stiff suspension. Your drivetrain needs attention in order to deliver power effectively. Most BMWs feature comfortable clutch discs, heavy flywheels, long shifter throws, and open differentials. The drivetrain transmits power to the wheels, but can also be a source of power loss when it is designed for comfort rather than performance. Everything on this page will help you improve your power delivery and driving experience by providing custom Limited Slip Differentials, Short Shift Conversions, Performance Clutch Discs, Lightweight Flywheels, and anything else your BMW needs to be the perfect driving experience.

A unique lubricant containing a suspension of solid microscopic particles as an extreme pressure agent--unique solid dispersion which cushions gear teeth to help prevent tooth breakage and allows the use of lower viscosities. Recommended for heavily-loaded racing differentials and transmissions, Off Road racing and problem gearboxes. The viscosity characteristics allow the lubricant to resist throwoff and provide a film thickness similar to a 75W250 grade, while providing the same low fluid friction as an SAE 75W90. We have been using RedLine Oil in our street cars and race cars for years. Hands-down, it is the Number One brand of high performance lubricant for BMWs.

Red Line MTL may be used in transmissions which recommend 75W, 80W, or 85W GL-4 gear oils, or SAE 30 or 5W/10W30 motor oils. If a 90W GL-4 or SAE 40, 10W40, or 15W40 is required, MT-90 may be used. If the transmission or transaxle requires an SAE 90 GL-5 gear oil, then Red Line 75W90NS or 75W140NS Gear Oil may be used.

Add to your limited slip differential to improve the fluid and wear prevention!

Features:

  • 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
  • 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
  • 4 oz. bottle

D4 ATF is a full-synthetic product designed with superior low-temperature properties compared to a Dexron III® fluid, and the improved shear-stability requirements which are part of the Mercon V® specifications. Synthetic D4 ATF is suitable for use where Dexron III, Dexron II, or Mercon fluids are recommended. D4 ATF also provides a GL-4 level of gear protection, making it a superior product for transmissions and transaxles. The balanced frictional characteristics provide smooth and consistent shifts for extended drain intervals. The superior stability compared to petroleum ATFs allows high-temperature operation without varnishing valves and clutches which leads to transmission failure. D4 is similar to Red Line's MTL formula and can be used in many BMW manual transmissions where MTF or MTF-LT2 is called for. Meets or exceeds the following BMW & MINI specifications: 83 22 9 407 807 (LT 71141) 83 22 0 024 359 (ETL-8072B) 83 22 0 026 922 (ETL-7045E) Dexron® III ESSO LT71141 MTF-LT-1 MTF-LT-2 Toyota Type-IV

    Red Line CV-2 Grease

    Experience unparalleled performance with Red Line CV-2 Grease, expertly crafted to endure extreme temperatures and pressures found in high-performance wheel bearings and CV-joints. This premium grease surpasses both conventional and synthetic options with its exceptional high-temperature stability, superior extreme-pressure protection, and water resistance. Operating effectively in temperatures spanning from -100°F to 500°F, it offers outstanding oxidation and corrosion resistance, minimal evaporation and oil separation, and has minimal impact on rubber seals. Expect a remarkable 200% to 800% increase in bearing life due to the exceptional extreme-pressure performance and synthetic oil fluidity. Its red moly compound outshines black moly disulfide lubricants, ensuring superior lubrication.

    Red Line CV-2 Grease finds application not only in automotive settings but also in industrial environments. It excels in high-temperature alternator bearings, high-speed ball bearings, conveyor bearings, worm gear drives, servo mechanisms, and other scenarios prone to fretting wear and corrosion. Its consistency and extreme-pressure performance endure high-temperature and high-shear conditions, extending the performance life of lubricated components. Despite darkening after high-temperature use, its efficacy remains unaffected. While compatible with some petroleum-based greases, it's recommended to clean out old grease thoroughly for optimal lubrication performance and to avoid grease incompatibility.

    Product features:

    • Outperforms conventional or synthetic greases and lubes
    • Endures extreme temperatures and pressures in various automotive components
    • Excellent high-temperature stability, extreme-pressure protection, and water resistance
    • Operates within temperatures ranging from -100°F to 500°F
    • Resistant to oxidation and corrosion, with minimal evaporation and oil separation affecting rubber seals
    • Contains organic moly for chassis lubrication and high temp/high-speed industrial equipment
    • Synthetic fluidity increases bearing life up to 200%
    • Darkening after high-temp use doesn't impact performance
