Looks good. After being disappointed to discover that both of the kingpins on my Ace 44 trucks were loose, I decided to switch over to Krux Downlow kingpins. I used a little JB Weld to epoxy the locknut to the bottom of the baseplate, allowed it to cure for a few days, ran a tap through it and the Krux kingpin installed easily. I like how they are setup, but I will say that someone who skates their Ace on the tighter side will probably find that they run out of threads before the whole thing can be cracked down. I imagine this could be fixed using a different 3/8"-24 panhead bolt with more threads
