ECS BMW Drivetrain Parts for BMW X Series E83 (2004-2010)

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.

This brass clutch pivot pin is an upgrade over the stock plastic pivot pin. The brass pin will last a lot longer than the plastic piece and may save you time and hassle later on. The original plastic pivot pin is known to fall out, snap, or just wear out over time. At the least you get a very annoying squeak every time you depress the clutch. In a worse case scenario, the clutch fork won't be able to push on the throw-out bearing and your clutch will be useless. The only time to replace the clutch pivot pin is when the transmission is removed, so this brass upgrade can be installed during clutch replacements or a rear main seal service.

This braided stainless steel line replaces the stock hydraulic hose connecting your clutch slave cylinder to the clutch master cylinder. There are several deficiences with rubber, especially as it ages - when new the rubber expands and swells under pressure and the pedal can feel spongy. As rubber ages and is exposed to extreme temperatures the rubber can harden and even shrink (common on brake hoses), which results in a stiff pedal. Rubber clutch lines do not stand up to the stresses of hard use. ECS Exact-Fit stainless reinforced clutch lines provide more confident and dependable shifting by maintaining consistent line pressure, long lasting corrosion resistance, and increased protection from failure. These lines are reinforced with braided stainless steel mesh, affording superior expansion resistance. This resistance to expansion creates a firmer pedal, and a more direct clutch pedal feel. The signature red polymer coating provides additional protection from the elements and abrasion.

This particular stainless steel clutch line fits the following BMWs:
1999-2005 E46 3 Series (all) including 323i, 323Ci, 325i, 325xi, 325Ci, 328i, 328Ci, 330i, 330xi, 330Ci
2001-2006 E46 M3 (manual transmission only, no SMG)
2004-2009 X3 SAV including X3 2.5, X3 3.0

Worn rubber differential mounts will lead to the differential twisting and shifting around in the rear subframe. Not only will this be noisy but it's bad for driver confidence and bad for the chassis as well. Even on fresh rubber bushings the differential has deflection and twist, especially if the car has been modified for more torque. Since the differential is centrally mounted in the rear subframe, with all suspension mounts interconnected, a differential with too much deflection will affect handling and could even damage the rear subframe.

These 88A urethane E46 diff mounts are much stiffer than stock but still not as solid as our Turner aluminum/Delrin bushings. This set will resist twisting much better than the stock rubber mounts. Included are the two front diff mounts and the rear mount in the cover.
