I got some Krux Downlow allenhead kingpins and the white 92a bushings. I did both set, 44's and 55's. The bushings came with pivot cups, which Ive already had replaced the 44's twice now. They were a little tall, so I took a razor and trimmed them flush. JB welded the kingpin nut in the baseplate and let sit overnight. IT had just enough bite to get the trucks back together without having to shave the bushings. I did add a bit of loc-tite to the threads just for a bit of assurance. Skated the next day. Still loose, but way more stable and my front truck isnt flopping around anymore. Hope I'll get a bit more life outta these trucks. Pool coping blasted through the knuckles and Smiths lock in without that crazy nut scrape. Ledge and curb tricks felt the same too. The 55's came out great too, but I really dont skate that set up much, so I need to break them in a bit better.
