911 Carrera 2.7 RS / RSR axle drive 8:31 teeth 915 gearbox Porsche 911 Axle drive Porsche 915 35:8 (4.375)

We offer various axle drives for the 915 gearbox. The offer here is with a ratio of 35:8 (4.375).

This axle drive corresponds almost exactly to the early ratio of 31:7 (4.43), but is designed to be much more
stable. The ratio offered here is often used in motorsports because of this stability and the shorter ratio. Original
use e.g. in the Carrera 2.7 RS/RSR.

The axle drives we offer are very cleanly made and can also be used with a mechanical speedometer drive
(i.e. also in the early 915 gearboxes).

The parts are ground and of course run in/lapped in pairs. This guarantees very smooth running with a clean
adjustment. The exact setting for calibration is engraved on the pinion head.

Other ratios (on request):

7:31
8:31
10:31

These axle drives are installed during a gearbox overhaul.
