final drive?
Turbo Mini Forums

just a quick question, richard has kindly helped me out sorting the bits for my new box and i have some sc gears and drops on the way soon they are in a 1:1 ratio so he said whatever diff i put in will be the final drive ratio, i'm after 3.1 can i just ring up and ask for a cross pin diff with this ratio bit confused

The diff is a different thing to the final drive. The diff itself does not alter the gearing, what you need is a crown wheel and pinion. These two gears are what alter the final drive ratio.
The crown wheel is bolted to the diff and the pinion is on the mainshaft in the gearbox. By fitting a crown wheel and pinion with a different ratio of teeth you are altering the gearing.
If you order a crosspin diff, you will get a crosspin diff. If your wanting to alter the gearing you'll need a crown wheel and pinion.
Hope this helps.

You just need to get a x pin diff and bolt up your crownwheel (from 3.1diff) on to it.
