Hey,

I have a 373 lsd in my 78 jimmy, i recently picked up a pair of used 37's with 15z10 inch rims for dirt cheap. Will i blow my rear end up if i run these wheels on the road? when im wheeling? what about in the mud? what kind of gearing should i go for? the engien and trans is a 454 with a 4 speed granny low so i hit kinda high revs as is with 33's.

Really depends on how you drive it. Are you gonna abuse it? If you drive it with some common sense you should be fine.
