ball housing - gearshift lever Genuine Porsche part 99142401001

Upgrade the gear shift on your 911. 

The factory assembly leaves more to be desired. On top of the long throw of the shift, components that are crucial in the feel and service life of the shifter housing are made of flimsy, brittle plastic which degrades and cracks over time. This leaves you with vague and inconsistent gear shifts, something you don't want in a sports car on or off the track.

• 3 levels of height/throw adjustment
• 20% throw reduction on shortest lever adjustment (18% & 14% in other positions)
• Fits all 991 models with manual transmission
• Compatibility with 981 coming summer 2023
• Installs in factory location and is compatible with center console, shifter cables, and shift boot
• Complete replacement for factory housing (OEM# 99142401001)
• Machined from 6061 billet aluminum
• Delrin bushings for durability and longevity 
• Accepts OEM shift knob

The OEM shifter cables use large rubber ends to isolate the shifter from the transmission. These soak up your effort and numb the feedback and directness required for optimal shifting performance. The resultant sloppy gear engagement leaves the driver questioning if the desired gear is fully engaged. 

This also leads to over-extension and stressing of the cables as the shift lever is pulled beyond the limit. 
From a safety and reliability standpoint, the plastic snap-on cups also wear out over time and split causing the cable to pop off the transmission.

Our solution replaces the rubber and plastic internals of the OEM shifter cable ends with tightly toleranced aluminum and Delrin components, reliably held on with steel snap-rings.  

Also, the included cotter pins provide a safety redundancy to ensure the cables stay securely affixed to the transmission.  The result is excellent shifting feel, precision, and control with no added noise, vibration or harshness (NVH) and no chance for the cable ends to pop off.

Fits:
Porsche 991.1 - 2012 to 2016
Porsche 991.2 - 2016 to 2018
Porsche 992 - 2019 Onwards

The Classic Gear Knob from Function-First Performance is designed to reconnect drivers to their vehicles.

Factory gear knobs contribute to sloppy and vague gear changes due to their rubber and plastic construction. To remedy this, our Classic Gear Knob is machined from solid billet aluminum for a superior shifter feel, ensuring that all shifting effort is transferred to the gear lever.

The 2-inch diameter knob fits securely in the palm, with the circumferential cutout providing dexterity and enhancing grip. The base shaft is machined specifically to fit Porsche’s rectangular shift lever and attaches securely via high-hold set screws, entirely hidden from view with the standard height shaft. The OEM shift boot integrates seamlessly at the base for factory-like fit and finish. If your current shift knob setup has an integrated 1-piece shift knob/boot (pre-997 Porsche models), you can cut the boot off to use with the Classic Shift Knob.

Aluminium - machined from a solid billet and anodized, this knob offers added weight for less notchy shifts

Shift pattern engraving with paint-fill is also offered for an added OEM look.

PLEASE NOTE:  Fitment is for Manual Transmission vehicles only. The OEM shift boot is shown for illustrative purposes and is not included.

Purchase price for the "CLASSIC SHIFT KNOB" includes only 1 shaft, 1 knob, and mounting hardware

Rennline Restomod Shift Knob 
The shift knob is a key driver-interface component, responsible for smooth, precise gear changes. The design improves the overall feel and control of the gear lever, offering a more direct and comfortable shifting experience. Its weighted design enhances feedback while reducing the effort needed between shifts, creating a balanced and engaging drive.

Why Do Shift Knobs Fail or Need Replacement?
Over time, factory shift knobs can wear, loosen, or fade due to constant handling, sunlight exposure, and age. Common issues include:

• Loose fitment: Causing missed or inaccurate shifts.
  
• Worn materials: Leather, plastic, or rubber deteriorating over time.
  
• Aged appearance: Faded surfaces that detract from the interior’s look.
  
• Cracked or detached knobs: Especially in older or frequently used vehicles.

A failing or poorly fitting shift knob can reduce driver confidence and affect the precision of your shifts.

Why Replace Your Shift Knob with a Rennline Upgrade?
Replacing your worn or stock shift knob with a Rennline Restomod Shift Knob delivers immediate improvements in feel, control, and aesthetics. Benefits include:

• Enhanced shift precision through a secure, vibration-free fit.
  
• Improved comfort and ergonomics for daily driving or spirited performance.
  
• Premium design that complements Porsche interiors - classic or modern.
  
• Durability and quality thanks to CNC-machined aluminium construction.

Whether you’re restoring a vintage Porsche or modernising your cockpit, this Rennline upgrade adds timeless style and mechanical precision to every drive.
