What we do on the 550 Spyder gearbox
Complete rebuild
stripping, cleaning, measuring every part, reconditioning bearing seats and gear teeth, setting up — finished with a test-bench run and photo documentation.New production from samples
worn or missing parts are measured from the original, drawn and made new — teeth ground, shafts heat-treated.Respect for substance
on a car this rare, every usable original part stays in service; only what is truly finished gets replaced.
Typical problems this solves
- Gearbox parts unavailable anywhere since the fifties
- Worn gear teeth and bearing seats after decades
- Restorations stalling for lack of a specialist in historic racing gearboxes
Why inquire here
The 550 Spyder forgives no approximations. We work with measurement reports and documentation — and with experience from every air-cooled Porsche gearbox, from the 356 to pure racing.
