Diff ratios

lanny man 90 · Feb 12, 2013

My back diff has a bit of a rumble so i have bought a tdci diff but was wondering if the ratios are the same as Td5s ? Or should I change front aswell Now in the summer am going to change the transfer box for a disco one as I would like it to be a bit more user friendly on the motorway or any Suggestions on what diffs to fit

I've had a search but all I could find was 300 vs td5

Cheers

should be standard 3:54 in them unless it was changed before you bought it.

Go to ashcroft and they have a good gear ration chart conversion thing. Might be cheaper to just change ring and pinions to say a 4:10. But tyre diameter mater for gearing correctly

I thought they'd be a different size like the TDi compared to TD5
