ST1 Classic Baseplate / Inverted Kingpin

The ST1 Classic Baseplate / Inverted Kingpin is a replacement baseplate for Slappy's inverted kingpin setup. The baseplate is the bottom half of a truck: it bolts to your deck and holds the kingpin, pivot cup and bushings that the hanger rides on. On an inverted kingpin truck the kingpin is flipped, so nothing sticks up into the grind path - the idea Slappy trucks are built around.

When to replace a baseplate

Replace a baseplate when it is cracked, when the kingpin threads have stripped, or when you are changing setups. The rest of the truck can stay in service - add bushings, pivot cups, kingpins and hardware if they are worn too.

Check fit on the Slappy size and spec chart first. If you are not sure which baseplate matches your trucks, email info@slappytrucks.com before you order.

Rebuild instead of replace

Slappy sells its parts individually so one worn piece never means a new set of trucks. With a Slappy tool a baseplate swap is a few minutes of work: unbolt the truck from the deck, pull the hanger off the kingpin, move the pivot cup and bushings over to the new baseplate, and rebuild in reverse. Browse the full truck wall if you would rather start fresh.
