BMW Drivetrain Parts

The stock center support bearing carrier is engineered to minimize noise, vibration, and harshness (NVH) in the cabin by loosely securing the center bearing with a soft rubber bushing. However, this design allows the driveshaft to move off-center during launches and shifts, reducing throttle response and causing drivetrain oscillations. Over time, the rubber bushing can sag or dry rot, leading to misalignment of the driveshaft.

Prevent or fix this common problem with JXB Performance's Driveshaft Center Support Bearing Upgrade! This upgrade features a simple yet highly effective 2-piece design that makes installation and bushing replacement effortless. The stock carrier is cut away, and the JXB bushings securely "clamp" the driveshaft bearing in place, ensuring constant driveshaft alignment.

The Street bushing option from JXB is the most popular choice, offering a significant improvement over the stock design while keeping NVH levels minimal.

Note: Some light NVH, such as a soft hum, may occur at certain speeds. However, with a modified exhaust or open windows, it’s unlikely to be noticeable.

Installation is straightforward and doesn’t require removing the driveshaft. The 2-piece design clamps directly onto the OEM bearing, though removing the old carrier will require a cutting tool.

Turner Motorsport Dual Shear Selector Rod (DSSR)

Enhance your N54-equipped 135i or 335i’s driving feel with the Turner Motorsport DSSR. Designed to give your shifter a much more precise and solid connection, this DSSR replaces the OEM selector rod, eliminating the play and deflection that come from single-shear designs. Pair it with a Turner short-shift kit for the ultimate shifting upgrade.

Think of the DSSR as a major upgrade from the single-contact OEM rod, much like riding a bike with two hands instead of one: you have stronger, more precise control over each gear change. With its dual-contact setup, the DSSR “sandwiches” both sides of the shifter and transmission, creating a direct link that feels solid, eliminating the vague and sloppy feel of the factory setup.

Key Benefits:

Enhanced Precision: Significantly reduces deflection and play, giving you a more connected feel while shifting Compatible with Factory & Aftermarket Shifters: Perfect for custom setups as well as stock configurations Durable Build: Fabricated from high-quality 303 stainless steel, offering rust resistance and longevity Complete Hardware Included: Comes with zinc-plated hardware for a secure installation Specifications:

Material: 303 stainless steel construction Compatibility: Replacement for part #25117524722 (E8X/E9X N54 models) Installation Design: Two-piece assembly with captive pins, designed for simple alignment and adjustability Fitment: Specially engineered to fit the tight N54 carrier without interference Installation Tips:

Remove your factory selector rod and take note of its orientation. Attach the DSSR to both the transmission selector joint and lower shift lever. Shift to 3rd or 5th gear for maximum access to the supplied hardware, then secure tightly.

Turner Motorsport Polyurethane Shifter Arm Bushing

Want more responsive and accurate shifts without sacrificing comfort? The Turner Motorsport Polyurethane Shifter Arm Bushing is the perfect enhancement to reduce unwanted movement and play in the shift arm assembly. Factory rubber bushings absorb vibrations for smoothness but compromise direct feedback and often wear out, leading to sloppy, imprecise shifting.

Crafted from high-performance polyurethane with a corrosion-resistant 304 stainless steel sleeve, this bushing maintains stability without stretching or wearing out like rubber. Experience the tactile feel of more precise shifts, with minimal NVH (Noise, Vibration, and Harshness) added to your drive. A must-have for any driver looking to take control of their BMW's performance.

Key Features:

Precision Control: Firmer than factory rubber for a crisp, responsive shifter feel Long-Lasting Materials: Made with durable 70a polyurethane and a 304 stainless steel mounting sleeve Easy Installation: Direct replacement—no modifications needed OEM Compatibility: Replaces BMW part numbers 25111222015 and 25111222652 Specifications:

Material: High-quality 70a polyurethane and 304 stainless steel Made in the USA: Proudly manufactured with quality materials Durability: Improved lifespan over factory rubber bushings, reducing slop and enhancing gear engagement

The main mounting bolt for the differential in the E36 is susceptible to shearing off during extreme driving conditions. This can cause internal damage to your diff, leaving you stranded at the track or on the side of the road. Active Autowerke's differential support bracket eliminates this issue forever in under an hour installation.

Previously used Active Autowerke Part Number AA-DSB-E36

This product fits the following BMWs:
1992-1999 E36 323i 325i 328i M3

Turner Weighted Shift Knob - 6 Speed:

Prepare for an elevated driving experience with the Turner Weighted Shift Knob. This 6-speed coin-designed knob not only feels fantastic but also enhances shifting with added weight, resulting in faster engagement. Crafted from billet 6061-T6 aluminum, CNC machined for precision, and anodized for durability, it's the perfect complement to Turner's short shift kits.

One of the most satisfying upgrades you can make to your BMW is to its factory shifter mechanism. By reducing the shifter's throw, you can give your manual transmission BMW a sportier, more precise feel. However, with so many different "short shift kits" out there, how can you be sure you're making the right decision? With the introduction of the Rogue Engineering OCTANE short shift kit, the choice is now crystal clear!

Rogue Engineering refuses to compromise with "lever substitution" as a method of short shift kit development. Rather than using actual test vehicles for their products, some companies actually dig through OEM factory parts diagrams to determine which factory levers can be substituted with others. This "lever substitution" method of introducing product is unacceptable. These shift kits have been developed and perfected through years of experience in proven short shifter technology, by Co-Founder, Ben Liaw. As longtime BMW enthusiasts know, Ben was single-handedly responsible for introducing and developing the idea of affordable, BMW factory-like, short shift kits for late model BMWs (BL/SS for those young enough to remember!). 

Rogue Engineering idea of a short shift kit is not substituting levers in place of factory ones just because "they fit". Throughout the 80s until recently, BMW was notorious for using only a few specific shifter levers for their manual transmission vehicles. For other companies, making just a few "replacement levers" and offering them in place of those factory part numbers was an easy way of calling it a short shift kit. Unfortunately, for those companies, BMW started using many different part numbers making it more difficult to just "swap in a lever".

Rogue Engineering only develops it's short shift kit with test vehicles in their facility, testing numerous prototypes, offering others to test it before settling on its final design. They feel that this old school, real world testing is the best way when modifying OEM ergonomic, sensory-based controls.
