What we do on the 911 gearbox
Rebuild to factory specification
fully stripped, measured, reconditioned — hypoid drive set up with original tooling, contact pattern checked, test-bench run included.Limited-slip differential
locking value 25–75 %, direct swap for the standard differential, original bearings and seals stay in service.Drive shafts and stub axles
any length, any spline profile, machined from a single billet and heat-treated.Motorsport options
RSR-style spray-oil lubrication, gearbox oil cooling, uprated shafts.
Typical problems this solves
- Second gear crunches, the synchromesh is finished
- Howling final drive — contact pattern and backlash no longer correct
- Inside wheel spinning at the limit: no limited-slip fitted
- Standard shafts not coping with increased power
Why inquire here
The 911 is the centre of our programme — from a single gear wheel to a complete exchange gearbox from stock. What the parts market no longer supplies is made on our own gear-cutting machines.
