I tried the TRX CVDs for the Jato and broke an out-drive cup within a couple battery packs. Maybe it was a fluke, but the stockers have held up wayyy better (still on stock set). Wouldn't be so bad if you didn't have to disassemble the diff to change from CVD to sliders...
Didn't get a chance to run it this wkend, but got the rears installed and it went easy enough. The CVDs only wiegh 6g ea more than the stockers btw. not too bad. : )
