Rebuild, don't replace

Trucks are the one part of a setup you can actually service. Fresh kingpins, baseplates, pivot cups, and hardware bring a beat pair of ST1s back to day-one feel for a fraction of the cost of new trucks - and every Slappy part fits every ST1.

Check the size chart if you are unsure what fits, or grab parts through your local shop.

Every ST1 is covered by the Slappy warranty - and if a question is not in the FAQ, the contact page reaches an actual person.

Slappy Trucks is skater-owned, founded by Mike Sinclair, and built on one idea: the truck should never be the reason you missed the grind. Sold direct and through the shops that keep skateboarding alive.

Slappy shares the Sidewalk Distribution warehouse with sister brands Opera Skateboards and Jacuzzi Unlimited - trucks here, decks there, one family.

Orders ship tracked from the warehouse, usually within a couple of business days - or ask your local skate shop to get you set up, which is always the right answer.
