Description

Sequential shift dog-change transaxle designed for use in transverse engine, two-wheel-drive race cars.

Features

  • Primarily intended to be installed in conventional front-wheel-drive cars, but also applicable for transversely mounted mid-engined cars, such as the Toyota MR2, Lotus Elise, KTM X-Bow or Ariel Atom.
  • Torque rating for endurance events is 700Nm (520ft.lb).

  • All gears have an extensive range of ratios available, the 1st pinion gear is integral with the shaft.
  • The internal lubrication system consists of a magnetic / paper element filter, an oil pump with provision for an external cooler, a spray bar to feed cooled oil directly onto the gears, through-shaft lubrication to all needle roller bearings and a jet feed through the differential.
  • Input is via a removable quill-shaft which can be customised to suit individual requirements.
  • Output is available with bolt up flanges, integral tripods, or can be customised to suit individual requirements.
  • Shifting is via a standalone gear-lever or a pneumatic actuator.
  • A gear position sensor is included for setting up shift cut and interfacing with an electronic dash.
    A stand along gear position indicator is also available.
  • Selector forks are manufactured from high tensile nitrided steel.
  • Case hardened nickel chrome steel is used for all gears and shafts.
