BMW Drivetrain Parts for BMW 3 Series E46 (1999-2005)

Sometimes choosing the correct shift kit proves difficult when you dual-purpose your favorite vehicle, we understand this well. The early days for any race enthusiast usually begins with a car that is needed to daily drive and setup to get out on the track. What becomes difficult is properly modifying that car to feel comfortable in both situations which is why we took this view on our new short shift line. This upgraded lever is a quick swap option to replace the standard shift lever that come with our kits so you can keep your hands closer to the wheel while shifting at high speeds. Designed from anodized aluminum this lever looks great in any interior for the daily driver who simply prefers the taller lever look and feel.

NOTE THAT THESE ARE DESIGNED TO WORK WITH TURNER MOTORSPORT SHORT SHIFTERS ONLY - We wanted to give you the option to buy one separately, in case you changed your mind after buying our short shifter.

Features:

Compatible with stock shift boot fits nicely into the machined groove at the bottom of the lever to maintain a clean look in the interior.
Machined from 6061-T6 aluminum and type II anodized for exceptional durability and corrosion resistance.
Available in either black or clear anodize to match your vehicle’s interior.
Rally shift knob is machined from black delrin.
Unlike aluminum, delrin will not hold heat so on those hot days you won’t have to worry about burning your hand on a knob that’s been baking in the sun.
Shift knob is threaded onto the end of the shift lever utilizing a standard ⅜-16 thread to allow for easy removal and attachment of your favorite beer tap or other accessory.
“Quick Change” height adjustable upper shift lever design allows for quick swapping between optional “OE” style and “Rally Style” upper shift levers.
22mm adjustment range to fine tune shifter throw and feel.

If allowed in the rules these solid aluminum transmission mounts offer many advantages over a urethane or Delrin mounts. It's no wonder that these mounts have found their way into the top BMW racers in the country. These are machined from solid aluminum and have zero deflection, engine torque will cause a rubber or urethane mount to flex or deflect allowing more torque to passed through the drive line (instead of being wasted winding up the mount). This puts the shift linkages in better consistent alignment. And unlike rubber or urethane the aluminum has zero wear and is not affected by leaking oil or other fluids so this is likely the last set of transmission mounts you will ever need. We very strongly recommend using the solid transmission and engine mounts together as a complete kit, mixing a rubber mount with a metal mount will cause undue stress on the mounting points and will lead to a failure. We never advise using a solid mount unless a corresponding solid mount is also used.

These are a no-compromise design for all-out racing use, full solid aluminum mounts should not be used on street-driven cars since there is no material to absorb vibration making these quite harsh for regular street use (track cars don't care about noise).

Single piece 6061 construction, optimized cooling, provisions for temp sensor and external cooler!

Built to last, made from a single piece of 6061 billet aluminum with a rugged and good-looking hard-coat anodizing our diff cover can handle anything you throw at it. Not only is it an absolute masterpiece to look at but this billet diff cover checks all the boxes for features needed. Reinforced mounting ears for strength and stability, never again will you break an ear off your diff cover like the factory units are known to do. Each ear is unified with the one-piece billet cover and features added material for the highest durability possible. This diff cover is cool, literally, the entire construction was designed with optimized cooling in mind. Internal fins are strategically placed serving as effective heat sinks for optimal heat dissipation. This ensures stable temperatures, promoting longevity for both the fluid and your differential. Additionally, the internal design ensures continuous oiling and lubrication of the ring gear, maintaining its stability and preventing fatigue by controlling heat more effectively. An internal baffle at the cover's corner helps maintain proper pressure and prevents cavitation.

All of the OEM features were retained along with the upgrades. The mounting surface was designed to be compatible with both the OEM gasket or RTV of your choosing, some people don't trust the gaskets and we get it. Factory bushing geometry allows you to use any E46 diff busing including rubber, poly, and even solid mounts. The drain and fill plugs on the diff cover are upgraded to -6AN using the provided high-pressure fittings with replaceable o-rings. The drain and fill plugs can now also be used for expanding to an external oil cooler allowing you to further expand the fluid capacity for optimized cooling and service intervals. To keep an eye on things from the driver seat is 1/8 NPT provision for temp sensors, this product from Turner has you covered at every turn.

Why the upgrade?

Upgrading to our Billet Differential cover gives you the strength you need to push your car to its limits. In addition to its enhanced strength, this differential cover includes numerous other upgrades and conveniences. These include increased capacity, improved cooling and lubrication for the ring gear, upgraded fill and drain plugs, and the option to expand an external oil cooler for extreme motorsport usage. Designed to complement both upgraded daily drivers and extensively modified track cars, all while looking good in the process.
