Like the original, from stock

Clutch-type limited-slip differentials as a reproduction of the Porsche original — built on the proven ZF principle, machined from high-grade CrMo steel on our own machines. Fitting the 901, 904, 906, 907, 908, 910, 911, 912, 914, 915 and 917 gearboxes, all available from stock.

Because layout and mounting dimensions match the original, the unit goes into the original gearbox housing with no modification needed.

Matched to your use

Locking value, separate ramp angles for drive and coast, and preload are specified for your intended use — what is right on a circuit rarely suits the road, and never a rally stage. The technical detail and the full configuration range are on the limited-slip differentials page.

For the 930 and 935 too

For the 930 and 935 gearboxes we supply limited-slip differentials and axle flanges — but not final drives. Send us your gearbox type and we will tell you straight away what is on the shelf for it.

Goes with it

Homologated gear pairs for the 901, 904, 906 and 908 — including the Nürburgring ratio, also from stock
Final drives in stock for nine gearbox types — ground, numbered, with measurement report
Fitting the differential into your shipped-in gearbox, including a fresh final-drive setup, as part of a gearbox rebuild

Common questions

01 Which gearboxes do the differentials fit?

The Porsche 901, 904, 906, 907, 908, 910, 911, 912, 914, 915 and 917 gearboxes — from the early production 911 to the works racers. Tell us your gearbox type and intended use and we will confirm the right specification.

02 What does "repro like the original" mean?

They are reproductions of the original Porsche clutch-type differentials — matched to the original in layout and mounting dimensions, machined on our own machines from high-grade CrMo steel. They fit the original gearbox without modification.

03 Are they available immediately?

Yes, from stock. They sit finished on our shelf and ship directly after your order — no production lead time.

04 Can the locking value be adjusted?

Yes. Locking value, separate ramp angles for drive and coast, and preload are matched to your use — road, circuit, hillclimb and rally place very different demands. Details on the limited-slip differentials page.

05 Can I get spares for an existing unit?

Yes. Clutch plates, pressure rings, bevel gears and shafts are available individually — including for original ZF units, whose internals are compatible with our parts.

Inquiry

What is on your bench?

Gearbox type and a few lines about your request — that is all we need for a first assessment. A photo helps but is not required. The answer comes from the machinist, not from sales.
