Skateboard Trucks

Slappy ST1 skateboard trucks, built skater-owned and made to grind. Mike Sinclair started Slappy to build the truck he always wanted: more grind clearance, smoother turn, and a kingpin that stays out of the way of your grinds.

Every kingpin style lives here - Classic, Hollow, the featherweight Hollow Lights, Inverted (Curb Killer II), Ultra Low Inverted, Low Profile, and the 13" wide boys - across the full ST1 size range.

Picking skateboard trucks: match the axle width to your deck so the wheels sit under the rails; go hollow to cut weight, inverted or ultra low kingpin for cleaner grinds and a lower center of gravity. Not sure which width fits? The Slappy truck size chart settles it in thirty seconds.

Order direct or grab a set through your local skate shop.

Every truck on this wall shares the ST1 DNA: engineered grind clearance, a turn that stays predictable at speed, and parts that interchange across the entire line - so a setup built today can be rebuilt for years instead of replaced.
