BMW Drivetrain Parts

The factory center support carrier features an internal bushing constructed from soft, pliable rubber. While this provides a smooth and quiet ride for standard driving, it falls short in performance-oriented applications where durability and precision are critical. During acceleration, shifting, and under load, the rubber bushing's inherent flexibility allows for excessive driveshaft movement. Over time, repeated stress and wear on the rubber will cause bushing failure, risking poor driveshaft alignment and efficiency. In extreme cases, this failure will cause a constant rotational "clunking" noise, a clear indicator of impending failure.

The ECS Tuning Center Support Bearing Brace is designed to enhance the performance and longevity of your drivetrain. To improve upon the factory design, and to create a performance alternative, our engineers started by designing a set of exact-fit, split low durometer rubber bushings that clamp around your existing driveshaft bearing. Crafted from 30A durometer rubber, our material choice effectively eliminates bushing deflection without causing an increase in noise, vibration, and harshness. By eliminating deflection, this design ensures a longer lifespan than the stock center support bearing, making it a great investment for enthusiasts looking to maintain their aging BMW chassis.

The rubber bushings are encased in a high-strength 6061-T6 billet aluminum bracket, engineered for both durability and performance. Like the bushings, the bracket features a split design, allowing for seamless installation without the need to remove the entire driveshaft assembly, saving time and effort during maintenance or upgrades. To ensure reliable clamping and secure fastening, the bracket is equipped with two corrosion-resistant stainless steel socket head screws. This design simplifies bushing replacement and provides a dependable and sturdy hold, even under high torque and stress conditions.

FEATURES

Exact-fit bushings are made from 30A durometer rubber to eliminate bushing deflection while maintaining a smooth, quiet ride.
Solid fill rubber construction offers a longer lifespan than flimsy factory rubber, ideal for enthusiasts looking to eliminate future CSB-related problems.
Bushings are encased in a 6061-T6 billet aluminum bracket for enhanced durability and improved performance.
Both the bushings and the bracket feature a two-piece split design, allowing for seamless installation without driveshaft removal.
Designed with performance in mind, this upgrade eliminates excessive driveshaft movement for improved alignment and efficiency.

Complete your Getrag 420G six-speed manual swap with a comprehensive shifter solution engineered for precision and durability. This all-in-one kit features our double-adjustable short shifter, dual-shear selector rod, heavy-duty shifter arm, upgraded bushings, and all required installation hardware for crisp gear engagement, reduced shifter slop, and confidence-inspiring performance you'll feel with every shift!

TURNER MOTORSPORT DOUBLE ADJUSTABLE SHORT SHIFT KIT

BMWs have historically been plagued by very long throw shifters from the factory - luckily, we've developed the solution. Our short shifter system is height- and throw-adjustable, offering up to a 52% reduction in throw over stock. Double adjustability enables you to find the sweet spot that will make you excited to drive your car again. Installation of this kit is also of the easiest to tackle. Compared to the competition, a custom bearing cup allows for easy installation from inside the car (on applications that use the stock shifter arm).

Benefits:

Adjustable between a conservative short throw to ultra short throw Ultra crisp shifter feel - quicker, more precise shifts More engaging driving experience Adjustability:

Independently adjustable knob height 22mm adjustment range to fine-tune shifter throw and feel. Note: knob height also affects throw reduction to some degree Independently adjustable shifter throw Adjustable by raising and lowering the lower lever position relative to the pivot ball. Note: ball position also affects knob height by ~10mm range Combined total throw adjustment range ​32 to 52 % reduction in throw over stock E36 shifter. A throw adjustment can be done in the car without removing the shifter DSSR (109MM) - E36 420G

Like all OEM selector rods, the factory part uses single-shear attachment, allowing for deflection within the shifter linkage. The result? Vague, imprecise gear selections that detract from your overall driving experience. The dual-shear selector rod (DSSR) design spreads the torsional force of gear selections across the selector rod joint, reducing deflection for increased precision. Our DSSR is precision-machined from durable 304 stainless steel to further reduce deflection and resist corrosion.

Features:

Provides a more positive feel in the shifter by reducing play in the linkage due to minimized deflection Manufactured from 304 stainless steel for superior corrosion resistance and durability Replacement for 25112228055 (European E36 M3 Evolution) HEAVY-DUTY SHIFTER ARM - E36 420G

To cater to the six-speed swap E36 community, we designed a direct replacement and upgrade for the unavailable, 420G-specific shifter arm. Precision-machined from 6061-T6 billet aluminum and clear anodized, this replacement carrier is durable, lightweight, and built to last. It is dimensionally identical to the OEM carrier, ensuring compatibility with the OEM shift carrier bushing, shift lever, and Turner Motorsport Double-Adjustable Short Throw Shifter Kit.

Features:

6061-T6 billet aluminum construction provides excellent durability and longevity Mil-spec clear anodized for superior corrosion resistance Dimensionally identical to its OEM counterpart, ensuring compatibility with all factory shifter components POLYURETHANE SHIFTER ARM BUSHING

This shifter bushing is designed to remove the shifter play caused by an old, failed rubber shifter bushing. Manufacturing the bushing from polyurethane instead of rubber reduces the amount of stretch caused by the moving part through the bushing. This maintains the direct crisp feel from your shifter assembly. When your OE shifter arm bushing begins to fail, you will notice slop in shifting, potentially making it easier to miss gears, and it often causes an obvious vibration and movement from the engine RPMs.

Features:

Corrosion-resistant 304 stainless steel mounting sleeve with bonded 70a polyurethane Stiffer bushing results in a crisper shifter feel and a more engaging driving experience.
