BMW Drivetrain Parts for BMW X Series E53 (2000-2006)

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.

Transmission fluid is responsible for both cooling and lubricating sensitive transmission components. Over time, this fluid becomes contaminated by particulate from clutch and gear components wearing down. This contamination reduces the fluid's ability to act as a lubricant, eventually leading to increased wear and tear within the transmission. To prevent excess wear and keep your transmission in top shape, the fluid and filter should be replaced regularly. As per ZF's recommendations, we suggest performing a full service on your 8HP automatic transmission every 50,000 miles. If your vehicle has been modified to produce more power than stock or if it is regularly track-driven, we recommend shorter 30,000-mile service intervals. This will ensure your transmission's fluid is free from contamination, which will help extend the life of internal transmission components, such as clutch packs and solenoids.

Automatic transmissions are reliable, shift smoothly, and can last without issue so long as they are properly maintained. Over time, the transmission fluid becomes thick and the filter becomes contaminated with small metal particles. This can cause excess wear, high transmission operating temperatures, and eventual failure. To prevent this we recommend changing your filter, fluid, and seals to ensure your transmission continues to operate flawlessly. We recommend filter and fluid changes every 50,000 miles. This kit includes Redline D4 ATF, the transmission filter, gasket and bolts.

Kit Includes:

  • Automatic transmission filter with associated hardware
  • Oil pan gasket
  • Drain plug with sealing washer
  • Fill plug with sealing washer
  • 6 quarts Redline D4 automatic transmission fluid

Fits the following BMWs:
E31 BMW 840Ci (from 09/1996)
E39 BMW 540i (from 01/1997)

This is a performance replacement for BMW Part # 21207533868 Aluminum flywheels are much lighter than the stock steel flywheel and that produces better throttle response and more available horsepower to the wheels for faster acceleration. The JB Racing aluminum flywheels are a direct replacement for the stock flywheel and work with stock clutch components for an easy upgrade with very little downside.

Modern flywheels are built with additional components and features that are designed to dampen and minimize vibrations from the engine and transmission. As a result they have become bloated in weight and that means more energy is used up just making the flywheel spin. The weight difference between an aluminum and steel flywheel is huge - sometimes more than 50% less. Without the additional mass, more energy can be diverted to where it counts most - moving the car. The flywheel and clutch is one of the first areas that engine builders address when making the rotating assembly lighter for race engines. The dampening effect is just not needed on cars that are focused on performance.

In addition to releasing more power to the wheels, the lighter flywheel allows the engine to spin more freely, which improves throttle response. Again, the difference is huge as you watch the revs build faster than before. With the engine spinning easier the power band comes up much sooner. The stock steel flywheel feels lazy in comparison. There is a driving adjustment required to get used to how much faster the engine revs but that's not really a downside.

The JB lightweight flywheel is designed to be used with a factory organic clutch - the same clutch kit that you would get from any BMW dealer. This makes replacement clutch components easy to source and inexpensive when compared to specialized racing clutches. By using the factory BMW clutch, JB has also made the whole assembly easy to live with when used on the street. The clutch behaves the same as it originally did - just with better throttle response and more power! The JB flywheel can also be rebuilt with a new clutch contact surface - you don't have to buy a new flywheel.

Aluminum flywheels are considered 'single-mass' flywheels because they do not have the same dampening designs as an original 'dual-mass' flywheel. With a single-mass design more noise and vibration may be noticeable. There are steps you can take to minimize the noise - heavier weight transmission oil and clutch discs with anti-rattle springs (sprung-hub clutch).

The JB Flywheel includes the pilot bearing mounted in the flywheel hub, just like the factory configuration.

Stock Flywheel Weight = 25.0lbs
JB Flywheel Weight = 10.5lbs

This item fits the following BMWs:
2002-2005 E46 BMW 325i 330i (with 6-speed manual transmission)
