Everything needed to completely remove all the slop from your shifting. All motion on the shifter is directly transferred to the transmission.
Features:
OEM Fitment: A direct swap and fitment from original shifter. Nothing required but a few common use tools.
Self Centering: Dual self centering springs (pictured yellow mounts, but will be black in final product). The shifter is centered automatically in the 3-4 plane (915 transmissions) or 2-3 plane (901 transmissions) or 1-2 plane (930 transmissions). No more spaghetti-like shifting or the shifter bouncing around. Multiple spring sizes gives a variety of side to side tension options based on your preference.
Throw reduction: Throw reduction of up to 40%. Use of a longer shift knob can increase the throw so it is only reduced by 30% if 40% is too much for preference. No more rowing.
Adjustable Reverse Lockout: Does your reverse gear get skimmed even with the stock reverse lockout? Our reverse lockout is adjustable so that it is dialed in perfectly to each car.
All Stainless Steel Hardware: All hardware is stainless steel and all aluminum is anodized. Rust won't be a worry with our shifters. Also, the reverse lockout and the bottom of the shifter is hardened steel for wear resistance.
Ball Bearings on Every Moving Axis: We remove all bushings and clips that hold the stock shifter in place and bare metal to metal contact for pivot with ball bearings. This is how we are able to remove all the play from the shifter and provide precise shifts.
Shift Rod Linkage:
-The ONLY aftermarket shift linkage that is maintenance free that isn't a U-Joint. Buy and install once, it isn't fun to keep adjusting this stock linkage every time you swap the bushings.
-No wear or play that is introduced from wear because we don't use plastic bushings. Any small play in this linkage is translated directly to the shifter, so get rid of the stock.
-Directly replaces OEM shift Linkage.
Disclaimer: The 2mm Spring option comes with yellow bushings instead of black

Porsche Gearshift Control Parts | Precision Engineering for Smooth & Accurate Gear Selection
Gearshift control parts form the vital link between your Porsche’s gear lever and transmission. They ensure smooth, precise, and responsive gear selection — translating driver input into clean, accurate engagement of gears. Whether manual or automatic, the integrity of your gearshift system directly impacts driving feel, safety, and transmission performance.
At Design911, we supply high-quality gearshift control parts designed to match or exceed original performance standards. Crafted from durable materials and engineered for precision fitment, our range includes linkages, bushings, cables, mounts, and selector mechanisms to restore crisp shifting and eliminate play or vibration.
Whether you’re replacing worn components or upgrading for enhanced performance, our Porsche gearshift control parts deliver improved shift feel, reliability, and driver confidence.
What Do Gearshift Control Parts Do?
Gearshift control components ensure that movement from the gear lever is accurately transferred to the gearbox or selector mechanism, enabling proper gear engagement.
Core Functions:
- Transfer motion from the gear lever to the transmission.
- Maintain smooth and accurate gear selection.
- Absorb vibration and prevent excess movement in linkages.
- Provide tactile, responsive feedback during shifting.
- Ensure consistent alignment for both manual and automatic systems.
Without properly functioning gearshift components, gear
changes may feel loose, inaccurate, or noisy — leading to wear and potential
gearbox damage.
Why Do Gearshift Control Parts
Fail or Wear Out?
Over time, gearshift components experience constant mechanical stress, heat, and vibration, leading to wear or misalignment.
Common Causes of Failure Include:
- Worn bushings or linkage joints causing play in the shifter.
- Cable stretching or detachment in cable-operated systems.
- Cracked mounts or fatigued metal joints.
- Corrosion or contamination from dirt and moisture.
Misalignment from hard shifting or vibration.
When these parts degrade, drivers may experience sloppy or stiff gear changes, difficulty engaging gears, or excessive movement in the gear lever.
Why Replace or Upgrade
Your Porsche Gearshift Control Parts?
Replacing worn or damaged gearshift control components
restores crisp shifting, precise engagement, and driving confidence. Upgrading
to performance-grade linkages or bushings provides improved tactile feedback
and reduced shifter movement.
