BMW Drivetrain Parts for BMW E21 320i M10 1.8L

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 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

    This clutch release bearing sits between the clutch fork lever and pressure plate, transferring pressure from the clutch fork to the pressure plate to engage and disengage the clutch system. If your clutch is making a rattling, chirping, or grinding noise when pressing the clutch pedal, there is a good chance your throwout bearing has failed and needs to be replaced.
