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
