Looking for a locker for the front differential on a 99 RR P38. Installing an Ashcroft on the rear with 4.10 gears. Will consider a LSD option as well...TrueTrac.
We found that the stock CVs don't do at all well with anything but an open diff. I've looked all over for a HD CV option but haven't been able to find anything.
I've been reading the same. Also open to anyone with a front differential with 4.10 ring/pinion (preferably reverse cut) on a 3rd member with low miles on the bearings.
