Slappy Trucks ST1 Inverted Hollow Light/Ultra Low Kingpin Polished 9.0 (Sold as Pair)

Slappy Trucks ST1 Inverted Hollow Light / Ultra Low Kingpin Polished 9.0 (Sold as Pair) are built for skaters who want maximum grind clearance without sacrificing control, strength, or feel. Right out of the box, these trucks show off a clean polished hanger and baseplate with a no-nonsense, functional finish that looks just as good on a fresh setup as it does after weeks of curb abuse. The inverted Ultra Low hollow kingpin sits flush and out of the way, paired with a hollow axle to reduce weight while keeping everything solid under heavy skating.

The geometry is where these really shine. The ultra-low kingpin and shorter top bushing create noticeably more clearance, helping eliminate hang-ups on ledges, rails, and crusty spots. The forged baseplate adds strength without bulk, while the refined pivot and bushing setup delivers a fast, responsive turn that snaps back clean every time. You’ll feel less wheel bite, quicker lean, and a smooth, predictable carve whether you’re locking into grinds or pushing through tight transitions. Best of all, there’s no break-in time—they feel right from the first push.

Slappy Trucks was created by skaters who wanted trucks that solve real problems, not just repackage old ideas. With a focus on grind clearance, turning response, and durability, Slappy has quickly earned a reputation for making trucks that are truly fun to skate. The ST1 Inverted Hollow Light model has become the gold standard for skaters who prioritize ledges, curbs, and technical street skating, and the 9.0 size is a perfect match for wider decks and shaped boards that need stability without losing agility.
