Our Sprite 4 speed manual boxes are made from Patterns and casting made in the UK, available in both Aluminium LM25TF or Magnesium. 5 different ratios are produced, some to ordered.

These differ from the originals as the bearings are obsolete which meant modifications which allow for modern metric races to be used and 3 piece roller races.

Well proven in many VSCC race cars and standard Sprites.

Usually supplied to allow for use with a Borg&Beck clutch/flywheel (also Manufactured for most Pre-War Riley engines) Can be supplied to take Original Riley clutch lifter.

Also see Gearbox rebuilds subpage under "About" page for many more options.

New: Silent 3rd gears for All Helical gearboxes.

Note: As Ralf Wren has passed on, the patterns were his, and his business has become obsolete. We can no longer offer Magnesium gearbox cases and when the next two boxes are sold that will be the end of production. So if you think you might want one in the future…move now before it is too late.
