This 4H-TECH K2-Shift is especialy designed for the newer model F40 Transmissions which are fitted with the upgraded shifter shaft (All Opel/Vauxhall from model year 2017 and younger). This K2 Shift is a next version of our very popular K-Shift. (which is still available for the older type F40 transmissions from 2013-2017)
A real power shifter which reduces shift times, so up coming gears can be engaged faster. By fitting this shift linkage you will have a gear throw shortening of about 30%.
The factory gear stick model and height remains unchanged. The short shifter will be fitted on top of the gearbox where the shift linkage is located. Gear changes are much quicker and precise.
One of the must have modifications to your car!
