Thread: Diff Ratios

re the original question, going from 32s to 35s affects gearing by about 15%. To fix it in a disco/range, you've got 2 choices. Either change you t/case hi range from 1.2 to 1.4, or secondly, change your cw&p from 3.54 to 4.11.
Defenders have 1.4s already, do you're limited to the cw&p solution.

Avoid the 4.10s. 4.11s are stronger.

re the second question, a Salisbury can be converted to 4.11 Dana 60 relatively easily, provided tou get the right shims & bearings etc.

Yukon Gear & Axle

The conversion from P38 to Salisbury has produced a tighter, quieter driveline btw.

Yanks don't seem to use pinion flanges, the strongest setup was a yoke pinion, which mates up to a Ford 9" uni. Its not going to break.

And a maxidrive fits.

Thanks for that everyone,

Tusker, what set up did you go with and what sort of ginning around did you have to go through for it to work.??

Cheers

OK, I'm being pedantic , I think the 4.3 should be 4.27 as I'm pretty sure that's what was in my two Jeeps (one was a D60 rear, the other a D44)

Wooders was advertising a couple of years ago 4.11's for D60 and D44 as well.

4.10 and 4.11 are not the same, may be in ratio but not strength from what I have heard.

well there are a couple of links to the salisbury 4.11's above - I don't really want to know how much they cost though!

Thats correct. they are a different tooth count. 4.1's are 10/41, and 4.11's are 9/37. They both have the same size gear head on the pinion which also loads the CW, but the 4.11 has bigger stronger teeth.

Could the GBR ones be D60's as D60 is part of the part number ?
