i have about 1 board worth of life left on my lurpivs and they are fine for me. I tightened them slightly throughout the life of the truck. They dont feel crazy loose for me by any means. I do remember them feeling super insane, very hard to skate the first day or two i had them, but i got used to it pretty quickly. I had a really un-ideal setup too with really long WB and I was skating fine enough on them, i was ollieing stuff my max height and pushing top speed into grinds. putting a lower height hex nut and shaving down the kingpin would make these trucks actually PERFECT imo. The bushings are actually really good.
i have a short 14" wb board on them now that i havent skated other than doing a few flatground tricks in my basement, felt so good like that compared to the 14.5". hoping the kingpin clearance doesnt drag on round bars too much, maybe will ask my friend to grind down the kingpin at his dad's machine shop like he did if its getting annoying and i want to keep using the trucks.
