Top quality from our own production
We machine the complete final drive — crown wheel and pinion — for the 901 gearbox of the early 911 on our own gear-cutting machines in Germany. The teeth are ground on the drive and coast sides to a tolerance in the region of 0.0025 mm, not milled and lapped. Serial numbering, a measurement report and the setting dimension for optimum running etched into the face of the pinion come with every set.
In stock, ships immediately
Like all nine final drives in the programme — from the 356 to the 917 — the 901 unit sits finished in stock. Inquire today, delivered with no production lead time.
Set-up and installation from one source
Backlash and contact pattern decide what even the best final drive ultimately delivers. On request we therefore set it up to factory specification and handle the installation — a gearbox rebuild or a limited-slip differential can be taken care of in the same job. More about the gearbox itself: 901 gearbox.
