Shifter Upgrades and Components for BMW 1 Series E82 (2008-2013)

New for your N54-powered 135 or 335 is our Dual Shear Selector Rod (DSSR) to deliver a more controlled and tighter shifting experience over the factory selector rod. Pair our N54 DSSR with our Double Adjustable Short Shifter for the full upgraded shifting experience. This DSSR is designed for BMW N54 models that have the selector rod p# 25117524722.

Upgrade from your single connection selector rod to a dual shear selector rod or DSSR for a stronger connection and an overall better shifting experience. The factory BMW selector rod is made of hollow aluminum tubing and attaches to both the shifter and transmission from one side utilizing a pin-and-clip design. The factory single-side attachment only has a small amount of surface area contacting both the shifter and transmission selector which relies directly on the connecting pin to do all of the shifting and control, this can cause a loose and/or lackluster experience when shifting gears or shaking your shifter in neutral. Your new Turner DSSR features a much larger contacting surface to both the shifter and transmission, not only does the upgraded DSSR have larger faces contacting your shift components but it also features double the amount of mounting surfaces. This dual shear selector rod hugs your shift lever and selector tight from both sides and eliminates deflection and sloppiness for the best shifting experience possible.

Features and benefits:

Provides an increased shift feel by reducing deflection and play in the linkage.
Works with factory and aftermarket Turner shifters
Manufactured from 303 stainless steel for superior corrosion resistance.
Includes zinc-plated hardware.
Design:

2-piece split design with captive pins
Replacement for 25117524722 (E8x/E9x N54 Cars)
Designed precisely to fit around the confines of the restrictive N54 carrier, clearing all critical fitment areas as you shift through the gears.
Installation:

Note the orientation of your factory selector rod upon removal
Once your factory selector rod is removed, attach the two-piece DSSR to the transmission selector joint and the lower shift lever. Once the two pieces are pressed together, move your shifter to either the 3rd or 5th gear position to give yourself maximum room to install and tighten the supplied hardware.

The ULTIMATE shifter upgrade for your BMW! Experience more precise throws, less shift lever travel, and an all-around transformation in your shifting experience.

For dozens of years, enthusiasts have critiqued the imprecise and vague feeling of BMW manual transmissions. Plagued with long throws, fore and aft play in gear, and a generally loose feeling, your OEM BMW shifter leaves much to be desired. While most standard carrier-mount short throw shifter kits will aid in reducing throw length and eliminating side-to-side play in gear, some enthusiasts long for a hardcore, race-inspired shifter that completely removes play and excessive throw length. At Turner Motorsport we share the same desire and set out to offer the ULTIMATE upgrade with this Performance Chassis Mount Short Shifter.

WHY UPGRADE?

Factory BMW shifter assemblies are complex by nature. The main component of this assembly is the shift carrier, a cast aluminum piece positioned inside the transmission tunnel that incorporates bushings at both ends for mounting. Like most factory parts, these bushings are designed to reduce NVH (noise, vibration, and harshness) transmission to the cabin. To the spirited driver, however, these bushings translate to flex and vagueness in the shift lever. Moreover, because this carrier is mounted to both the transmission and the body, the entire shifter assembly will "float" with the driveline, further increasing the vague and imprecise feeling of your shifter.

Our Performance Chassis Mount Short Shifter removes the shift carrier assembly entirely—removing any prospect of flex caused by bushings or driveline movement. By contrast, this chassis mount shifter offers a drastic reduction in shift lever travel, vagueness, and side-to-side play. An elevated base allows for moving the fulcrum point upwards, resulting in a much shorter and more precise throw. Shift times are further reduced by a tall, "rally style" shift lever, used to aid in leverage while also bringing the lever closer to the steering wheel. Our design incorporates a proprietary centering spring design, which is adjustable for increasing or decreasing self-centering force. In short, this design eliminates all the drawbacks of your factory BMW shifter, translating to more control, greater precision, shorter throws, and faster shift times.

FEATURES & BENEFITS

Reduced Throw: Modified shifter geometry and heightened fulcrum point translate to a shorter shift lever throw
Improved Shifter Feel: Eliminating the shift carrier and associated bushings drastically reduces "slop" and side-to-side play in the shift lever
Increased Precision: Mounting the shifter to the chassis allows for little to no variation in gear selection
Universal Fitment: Fits many BMW chassis with the provided base plate and hardware (see "Fits These Cars" for exact fitment information)
DESIGN

6061 aluminum, 4130 steel, and 316 stainless steel construction
A type-II black anodized finish
Adjustable self-centering spring
"Rally Style" shift lever
Spherical bearing pivot with maintenance-free brass insert
