ratios Ratios

A common requirement is for replacement ratios and final drives, we are able to provide the parts that suit the original application but are manufactured with modern tooth forms and materials.

We can offer more than to just sell you a ratio, we can give advice and suggestions to help you get the best out of your gearbox.

Ratios

With the multitude of options and changes throughout the years, sometimes just knowing what type of gears or final drive your gearbox has can be a challenge so please use the table below to help you. Clutch rings are normally straightforward, but for those with a gearbox that used FT or DG styles depending on the year it was produced, please see our dimensioned drawing so you can get the correct parts first time.
