If you’ve ever done enough grinds to totally ruin your kingpin nut, got hung up on a crack in the pool coping mid-smith, or tried to ollie-to-pogo only to smash a round hole in the side of your shin, you should probably try these inverted kingpins out. It’s a 2″ long kingpin with a slim hexagonal head, a 5.5mm or 7/32″ allen slot, and rounded edges. You put the nut underneath the baseplate, and then this rounded head sits below the hangar, (hopefully) eliminating all your kingpin-based woes – and, unlike other inverted kingpins, you can still adjust it with a regular skate tool, so you don’t get stuck with a rounded-off allen socket and an unadjustable truck.

This isn’t just a kingpin upgrade, though; these also come with replacement washers and a set of 85a Film bushings, complete with the hangar insert on the top bushing. It’s a total truck improvement kit.

However, note that these kingpins rely on a proper hex slot in the baseplate – which a lot of modern trucks don’t have. Check the chart below to see the trucks we’ve checked these will work with.
