I am so in awe of this build man, definitely on point. I love the 1/8th scale with the Digger axles, they fit this truck perfectly. So well I am thinking of getting a pair for myself. $180 a piece is steep, but we only live once haha. I do have a couple questions for you tho, can you run any 1/8 diff in the axles? Also what were your thoughts on the quality of the Kershaw centre diff?
