I agree, I would go with the UE diffs for sure. I have the stock diffgears, with an aluminum cup and an aluminum diff case. I have reshimmed them a few times allready. One time a just reshimed and put new gears in my diffs at my local track. I left the track with the rear diff gears brocken and the front diffs loose as a goose (same problem in the sand). Granted I'm a little trigger happy but it still sucks. Like Mike said earlier you will need to modify the spool to a bigger screw size. My spool bolts snapped on the first set of batt. The ulttramaxx tranny gears will also be a must. Currently I am waiting for my set that I ordered. My E-maxx has been sitting for awhile do to my smoked tranny and lack of $$. MY trigger happy finger and the beach sand put my E-maxx to the MAXX everytime. I hope with the new ultramaxx tranny gears, and a fresh rebuild on my diffs that it will be a solid truck, since the radio and the shifting servo is the only thing left to replace.
