Porsche 935 Gearbox – LSD & Racing Parts

ZF-based limited-slip differential, LSD service, gear and special parts

For the 935 — the Group 5 works racer — we supply the limited-slip differential and machine the gear and special parts that keep this turbocharged monument racing.

What we do for the 935 gearbox

  • ZF-based limited-slip differential
    dimensioned for turbo torque and racing use, locking value and ramp angles to the team’s setup sheet.
  • Gear and special parts
    gear wheels, shafts and small parts from sample or drawing — ground to the region of 0.0025 mm.
  • LSD service
    refresh and setup changes between events, all internals individually available.

Typical problems this solves

  • Racing wears plates and pressure rings predictably — spares must be just as predictable
  • Setup not matching the track: too much or too little locking
  • Individual gearbox parts finished after decades of racing

Why inquire here

Historic racing runs on deadlines: the car has to be ready for the event. With in-house production and individually available LSD internals, the 935 stays on schedule.

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.
