Our Turner Motorsport rear shifter bushing is a precision-engineered solution designed to eliminate excessive deflection in the factory BMW G8X shift carrier assembly. The OEM rubber bushing introduces unwanted compliance that translates to a vague shifter feel, imprecision under load, and potential gear misalignment during aggressive driving. This polyurethane and billet aluminum replacement addresses that with a focused approach to both material selection and mechanical function.
Our engineer replaced the soft rubber isolator with a 70A durometer polyurethane bushing housed in a CNC-machined 6061-T6 aluminum body. The result is a significant reduction in bushing deflection while retaining the necessary articulation for BMW’s dual-bushing shift carrier design. Strategically placed relief cuts in the poly insert allow controlled movement without compromising rigidity where it matters most, translating to a more direct, confident shift feel without introducing harsh NVH into the cabin.
By maintaining stock geometry and compatibility with OEM components, this bushing installs as a direct replacement for BMW part #25118623459, with no modification required. Ideal for spirited street driving, track use, or anyone seeking a more mechanical and connected shift experience.
Technical Specs:
70A polyurethane construction for optimal stiffness-to-compliance ratio
CNC-machined 6061-T6 billet aluminum housing
Type II anodized for corrosion resistance
Retains dual-axis articulation of factory shift arm
Direct fitment for G80 M3 / G82 M4 / G87 M2 (with manual transmission)
Performance Gains:
Drastically reduces lateral and fore-aft play in the shifter
Improves shift precision, especially under load or high-RPM shifts
Minimizes missed shifts and sloppy gear engagement

New for your G8x is our Dual Shear Selector Rod (DSSR), to deliver a more controlled and tighter shifting experience over the factory selector rod. Pair our G8x DSSR with our upgraded poly rear shifter bushing for the fully upgraded shifting experience. This DSSR is designed for G8x models that have the selector rod p# 25118097173.
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.

Enhance rear-end control and put more power to the ground with a straightforward 3-piece design that installs with ease. The factory rubber may favor ride comfort, but it struggles to keep up when driving gets aggressive. As it wears, the OEM bushing can soften and deform, reducing stability and allowing wheel hop to creep in when you need traction most.
Our 95A durometer polyurethane bushings solve that problem. Engineered to strike the perfect balance between soft factory rubber and harsh solid mounts, they significantly reduce differential movement without introducing excessive vibration. The result is more efficient power transfer, so your torque goes straight to the rear wheels instead of being lost in drivetrain flex.
Features & Benefits:
Minimizes differential movement and instability to help eliminate wheel hop
Two-piece 95A split polyurethane design for easier installation
Precision-fit insert reinforces the bushing and strengthens mounting points
Resistant to road salt, oils, and harsh chemicals
