BMW Drivetrain Parts for BMW 1 Series

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.

Differential bushings are responsible for keeping the differential in solid alignment while dampening drivetrain vibration. While OE rubber bushings are fine when they are new from the factory, aged and worn out rubber bushings create a multitude of issues that can range from annoying to dangerous. As a factory bushing ages, it begins to harden and become brittle. When this happens the bushing will actually shrink and allow for movement at the differential mounting point. At this point, the differential is free to shift under load causing a noticeable clunking noise under acceleration and deceleration and massively increasing the stress on the driveshaft and axles. Manual transmissions suffer the worst from this as it can make shifting difficult since the differential will shift when the clutch is engaged and disengaged.

By replacing these bushings with full polyurethane, the movement is eliminated since the mounting point is supported by a much stiffer material that will not harden or shrink over time. This means less stress on the driveshaft and axles and greater longevity of supporting components. 

Powerflex street bushings are ideal for street driven vehicles and those that see occasional autocross or track time. Need bushings for a dedicated track car? Powerflex Black Series bushings are the ultimate in track and race bushings. Featuring 95A durometer polyurethane, Black Series bushings are 25% stiffer than street bushings. Engineered to perform, Powerflex performance polyurethane control arm bushings offer a supreme level of control, while still providing enough comfort for the street, with advanced polyurethane that reduces NVH that often accompanies lesser bushings. Expect improved steering feel, turn in, more responsive handling and overall improved chassis composure with Powerflex performance polyurethane control arm bushings.

Poweflex is a leading manufacturer of aftermarket suspension bushings. Using state of the art design and manufacturing, all replacement bushings are engineered to out-perform and out-last the ones that came in the car. Each line of bushings is meticulously tested and then re-tested to ensure perfect fitment and enduring quality through the life of the vehicle. A full lifetime warranty backs every one of their products and demonstrates the level of confidence and commitment Powerflex has to their customers.

Powerflex is the number one selling suspension bushing manufacturer in Europe. Their experience with polyurethane bushing material and state-of-the art manufacturing techniques allows them to produce premium performance bushings, made to exact-fit standards. Powerflex performance polyurethane bushings are built to last longer than OEM rubber bushings, while improving performance and allowing for a more engaging driving experience. Powerflex is pleased to introduce their new N54, N55, and B58 Engine Mount Inserts, intermediate alternatives to the BMW aluminum inserts and much stiffer full replacement engine mounts available on the aftermarket. Made in Yellow 70A durometer material, they are designed to fit the OE mounts snuggly to restrict engine movement with a minimal increase in NVH, perfect for those with tuned road cars. Their design and flexibility also mean they can be fitted to the vehicle without removing the engine mounts themselves. Reducing engine/transmission movement by way of upgraded inserts has the following benefits: Sharper throttle response Improved gear shifting More direct power transfer More balanced on/off throttle handling Prolonged life of the OE mounts A small increase in NVH, usually at idle, should be expected when stiffening the connecting mount between the engine and chassis. The harder the material used, the greater the NVH transmitted.

As Used on Project E92 335i
A turbocharged BMW such as the 135i or 335i needs traction to put that power to the ground. The stock differential of both the 135i and 335i only put power to one wheel -- this just won't cut it! Upgrading to a limited slip differential means power to BOTH wheels, for better launch, acceleration, grip, and track handling. We're excited to be carrying the OS Giken LSD unit in our performance catalog, as we've used their products on our own Championship winning E46 and E92 race cars.

OS Giken's newest innovation is their quietest and smoothest limited slip unit yet - the Traction Control Differential (TCD). TCD is similar to their excellent Superlock differentials but with additional oil channels and pathways. The added lubrication makes diff operation smoother and quieter than before (not that there were many complaints to begin with). The locking engagement is more progressive than before which makes this diff more suitable for street driving. Track cars and drift cars should still use the Superlock LSD as it will transition to lock sooner. TCD is an evolution of a diff that was already extremely well-engineered for road and track use. Not willing to rest on their laurels, they took their superior engineering a step further.

With the 135i/335i LSD unit, they have incorporated revolutionary ideas into the overall limited-slip design which uses an unprecedented number of friction plates (up to 28 total!) for better locking force, better engagement/disengagement, and less generated heat. The use of highest quality materials, precise machining, forged gears, and sound engineering makes this LSD durable and reliable enough for road racing performance (which we can personally vouch for!). Zero break-in required. 100% progressive locking capability. 

Installation note: BMW differentials use many unique and BMW-only parts and components. Only technicians who are experienced and familiar with BMW parts should perform the installation. The OS Giken LSD is the limited slip unit (or 'chunk') only. It replaces the stock non-LSD chunk but the original ring and pinion and other internals must be installed with the OS Giken unit. This unit will only work on 335i manual differentials with a bolt-in or modified ring gear. Proper setup and spacing is critical for long life operation. Incorrect installation will void the warranty. We also offer the TCD unit pre-installed -  see our performance diff catalog for more info.

The OS Giken TCD Diff unit fits the following BMWs:
2008-2012  E82 BMW   135i with manual transmission
2007-2011  E90 BMW   335i - Sedan with manual transmission
2007-2013  E92 BMW   335i 335is - Coupe with manual transmission
