Ended up with a pair of Krux and in trying to ride them, I found that the turning radius isn’t nearly tight enough for me (I’m coming from riding thunders and Indy’s wobbly loose/almost wobbly loose) so I got to tinkering.
It turns out that if you put an Indy baseplate (keeping the Indy king pin and bushings so far) on a Krux hanger, you end up with an interesting mix of the qualities of both. They turn almost like Indy’s, keep the height that both trucks usually have, keep the lighter weight of the Krux hangar and also with the big king pin clearance of Krux. The wheelbase seems pushed out slightly further than Indy with this modification , but the pop feels virtually the same.
I think it’s because the square part of the top of the baseplate that the kingpin comes out of on Indy’s is significantly higher than that of Krux, so it pushes the Krux hanger forward slightly and elevates the back of the hanger which seems to give it a deeper turning radius. It seems like, when you press the wheel into the wheel well, that this Indy baseplate makes the wheel arc towards the center of the deck more than the Krux baseplate which seems to keep a straighter line to the wheel well when pressing the wheel down.
Anyway, I would not buy Krux with this modification in mind, but if you end up with a pair and want to screw around with them rather than letting them go to waste, this seems to help the turning problem.
I haven’t ridden them long enough to say for sure, but it doesn’t seem like this modification would put weird stresses on the truck that would make it break more easily either.
