Redline BMW Drivetrain Parts for BMW Z Series G29 (2019+)

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.

Red Line 70W/80W GL-4 MTL gear oil (SAE 5W30/10W30 engine oil viscosity) designed for use in BMW manual transmissions. Provides excellent protection of gears and synchronizers and its balanced slipperiness provides a perfect coefficient of friction, allowing easier shifting. The MTL can be used as a replacement for the factory MTF or MTF-LT2 used by BMW. Add MTL to older BMWs that have become tough to shift will restore shift smoothness. Many experts agree that this is best lubricant to use in BMW manual transmissions. Sold by the quart.

Red Line 75W90 is a full synthetic high-performance gear oil that is an excellent substitute for expensive factory fluid and an upgrade over off-the-shelf economy fluid. Red Line thoroughly evaluates the manufacturer's recommendations and only makes a fluid recommendation if their own product meets or exceeds the original specification. In many cases the Red Line synthetic will outperform the factory supplied fluids. We've been using Red Line Oil in our BMWs since we opened in 1994 and it remains our best selling BMW differential fluid. 75/90 is the weight most commonly used in BMW differentials since the 1960s, including the factory clutch-type limited-slip diffs (exceptions being M3/M5/M6 cars since 2001). We use 75W90 in nearly all BMW chassis and the custom differentials that we sell. It's great for the street where the polyol-ester base has natural lubricity and friction modifiers lead to smoother and quieter operation with lower operating temps than the factory fluid. We also use it in some track cars that don't already use the more aggressive 75/90NS fluid (without friction modifiers).

Recommended or exceeds specifications for API GL-5, GL-6, MT-1, MIL-L-2105E, SAE J2360, and Chrysler spec MS-9763. Matches the specifications for the factory BMW SAF-XO diff fluid (#07512293972).

Redline's 75W110 suprasses all GL-5 specifications, and its full synthetic formula is engineered to provide superior wear resistance with longer service intervals. Special friction modifiers for clutch-type LSDs allow for flawless operation even in extreme conditions. It offers less noise and higher film strength than 75W90 and less drag than 75W140, making it a great fluid for troubleshooting noisy gear sets.

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.

A unique gear oil designed to lubricate racing transmissions and transaxles which see serious loads (not recommended for most syncro-type transmissions). It has excellent low-temperature flow which allows easier shifting when cold. May be used to obtain maximum power transfer in racing differentials which do not see high temperatures. Similar to a 75W140 gear oil, but with the lower internal friction of an SAE 30 motor oil.Used in two-stroke and four-stroke motocross transmissions (often mixed in equal parts with SuperLight ShockProof™ Gear Oil). Used in most road-racing differentials with moderate power and dogring racing transaxles.

    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
