Gearshift Control Parts

Paradigm shifter - Stealth edition.



A WOLF in sheep's clothing, our new Paradigm Shifter- STEALTH EDITION, is everything our CARBON FIBER (CF) SHIFTER is, and less. Without the Carbon Fiber and Titanium of our CF SHIFTER, we are able to offer all the features and functionality of our CF SHIFTER, but at nearly half the cost. With our new STEALTH EDITION, you are able to run the factory shift boot and OEM-style Knob (both included), combining the ultimate STEALTH look with the ultimate in precision.

STOMSKI RACING'S long-awaited PARADIGM SHIFTER- STEALTH EDITION is a comprehensive new design, look, and function for the Porsche driver desiring a more precise shifting experience. With comprehensive features such as variable throw (20 or 30% reduction), reverse lock-out, fully neutral-sprung gates, and CNC machined components, 911 drivers can now predictably and confidently shift their Porsches. Our PARADIGM SHIFTER- STEALTH EDITION, is not just a kit to rebuild your factory shifter, or a bolt-on/add-on, it is a complete unit, engineered and manufactured for both the street and race environment.

Our PARADIGM SHIFTER comes complete with base, housing, internal components, boot, and shift knob (specify 911/901 or 915).

The STEALTH EDITION also includes a stock shift rod and an adapter for full 2" extension.

For all 911s up to 1986 as well as 914s (1970-72) with tail-shift transmissions.

Rennline 915 gear shift coupling bushings solid. 



Fits:
Porsche 356A / 356B / 356C - 1956 to 1965
Porsche 911 1969 to 1988
Porsche 911 turbo - 1975 to 1988

Product Description

If your 915 shift coupler has never been service or replaced and you're experiencing a loose and worn-out feel in your shifter, the culprit is likely the coupler. 

The factory-installed coupler bushings are constructed from low durometer compliant rubber, which tends to wear out quickly. Our upgraded brass bushing is designed to enhance shifter feedback and deliver precise shifts. It's the solution you've been seeking to optimize the performance of your 915 transmission.

Fits factory shift coupling - 91142402404 and 69542402404
