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.
