Porsche Cayman GT4 (PG81) 3.-6. gear set

High Performance Gear Solutions for Cayman GT4 synchromesh transmission


Holinger’s new gearset for the 981 GT4 is specially developed for the ambitious track day driver.
The optimized ratios keep the engine in the powerband by reducing the rpm drop between shifts and improve the top speeds to suit track conditions.

Holinger PG81 Gearset Features:

  • Ratios optimized for fast road, track day, and racing use.
  • Reinforced gears are made from superior VAR nickel alloy with strength-focused tooth profiles.
  • New gears are direct replacements and require no gearbox modifications.
  • Synchro dog-rings are splined to the gear - this prevents ring-detachment failure that has been known to occur in standard GT4 gearboxes (see close-up image below).
  • All gear teeth are profile-ground after heat treatment, ensuring the most accurate engagement and tooth finish - resulting in quiet, more efficient running.
