Hmm. The idlers do look like UE items for sure, but the other gears do appear to be the clones ( the finish n them is a little rough, compared to the finish you see if you do a google image search for 'ultraxxed gears' ). Like I said though, anything is better than the stock plastic gears so I imagine those ones will hold up perfectly well to BL power
Are the little input gears on the top shaft held in place with the stock roll pins, or have they been modded ( the roll pin snaps very easily under BL power, so guys swap them for short lengths of drill bit or allen key which is hammered & glued in place )?
Sexy beast indeed...
