Shifter Upgrades and Components

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

BMW Shifter Carrier Arm Bushings - Round are essential for enhancing shifting precision and feel in your BMW’s manual transmission. These 90A urethane bushings from Turner Motorsport replace the stock rubber bushings, which tend to wear out quickly, resulting in sloppy shifting. Designed to fit at the front of the shifter carrier arm, these bushings securely attach the carrier to the transmission, providing a stiffer connection that minimizes excessive play without increasing vibration. This upgrade is perfect for enthusiasts seeking a more responsive shifting experience.

These bushings are compatible with various BMW models, including the E30, E36, E46, E28, E34, E39, E24, and Z1 Roadster, and serve as a direct replacement for BMW part #25117519669. Installation is simple when the shifter carrier is removed from the vehicle.

Key Benefits:

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.

Turner Motorsport Chassis Mount Short Throw Shifter

Upgrade your BMW's shifting experience with the Turner Motorsport Chassis Mount Short Throw Shifter—the ultimate solution for precision, control, and race-inspired performance. Designed to eliminate excessive play, reduce shift throw, and enhance driver engagement, this shifter transforms your driving experience with a solid, direct feel that brings excitement to every shift.

Why Upgrade?

BMW's factory shifter assemblies are known for their vague and imprecise feel due to excessive play, soft bushings, and long throw distances. Traditional short shifters reduce shift length but often retain the factory shift carrier, which still allows flex and movement. The Turner Motorsport Performance Chassis Mount Short Shifter takes performance to the next level by completely removing the shift carrier, eliminating all bushing flex and driveline movement for unparalleled precision.

Unlike standard setups, this shifter features an elevated base that moves the fulcrum point higher, resulting in dramatically shorter throws and crisp, accurate shifts. The tall "rally-style" shift lever enhances leverage and positions the shifter closer to the steering wheel for faster gear changes. Additionally, an adjustable centering spring lets you fine-tune self-centering force for the perfect balance of resistance and smoothness.

Features & Benefits

Ultra-Short Throw – Optimized geometry and a raised fulcrum point drastically reduce shift travel for lightning-fast gear changes. Maximum Precision – Chassis-mounted design eliminates bushing flex and floating movement for a direct, race-inspired feel. Solid Shifter Engagement – Eliminates side-to-side play and imprecise gear selection for ultimate driver confidence. Adjustable Centering Spring – Customize the self-centering force to suit your driving style and preference. Premium Materials & Finish – Constructed from 6061 aluminum, 4130 steel, and 316 stainless steel with a durable black anodized finish for strength and longevity. Universal Fitment – Compatible with multiple BMW chassis using the included base plate and hardware (see "Fits These Cars" for exact applications). Race-Inspired Engineering

Designed for enthusiasts who demand the best, the Turner Motorsport Chassis Mount Short Shifter provides unmatched shift feel and precision. The spherical bearing pivot with a maintenance-free brass insert ensures durability and smooth operation, while the rugged CNC-machined construction withstands aggressive shifting and track abuse.

Take full control of your BMW’s shifting performance with Turner Motorsport’s ultimate short shifter upgrade—built for the road, perfected for the track.
