To all you guy running rockwells. i have a few questions.. how many miles have you put on the street with them?? How well do they act? any overheating of the diffs? i am looking at my options here. i am planing on one tons with some 42's but i would rather have a set of 47 or 49's. i am in ms so no rocks only mud and lots of it... this truck is not my daily driver but i would like to drive it to the mud holes/ mud bogs.. how are pinion brakes versus wheel brakes. what is the smallest rim dia you can runn. and one last one is there a "rockwells for idiots" thread??
