The old school dana 44 has 4.27s. These M210/220 axles jump from 4.10 to 4.56 with nothing in between. Unless some aftermarket company did non-factory ratios I don't know abour.
There are 4.30s for the M220. Nitro Gear & Axle M220JL-430-NG
Interesting. They also make that for the M200 rear. But not really useful since they don't seem to have the matching front gears for either the M186 or M210.
I wonder if there is some supply issue or something because I did find a GPJL-4.30-M220 part number which is for the M186 and M220 kit and it does seem to be out there but not listed on Nitro's website. I'm sure the demand isn't exactly high but how many people need to buy 2.75 gears for a Ford 9 inch in 2024? Summit racing has 2.75-7.40 listed for the Ford 9 inch though...which is a crazy good selection but obviously the Ford 9 inch is a legacy axle with uses so varied it would boggle the mind.
I wonder if there is a supply issue as well.
What engine and transmission?
I recall a thread where someone in an emergency situation where a not readily available non standard gear set created problems. Having blown a rear end on an out of state week long hunt, only losing 3 days I wouldn’t want non standard.
Probably not a good direct comparison.
I remember that thread. I think he was running 4.63 gears from Nitro.
The torque of the 6.8L is very close to the 392.
