Curb Killers

The Curb Killer II is Slappy's hollow inverted kingpin truck. The inverted kingpin sits flush in the hanger, so there is nothing to hang up mid-grind - more clearance, no kingpin bite, and a cleaner lock-in on ledges and rails. If you live on curbs, this is your truck.

The Curb Killer II is the inverted-kingpin flagship: the bolt drops out of the grind path entirely, which is the whole point - locks are cleaner, crooks stop catching, and the truck stays out of your way. If you skate ledges and rails first, start here. Check the size chart for widths.

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. That is the skater-owned math Mike Sinclair started the company on.

Buying for a specific deck? Match the axle width to the deck width and the wheels sit where they should - the size chart maps every Slappy width to the decks it fits. Orders ship tracked from the Sidewalk Distribution warehouse, or your local shop can order any of it in.
