FAQ

Will ULKP bushings fit regular trucks?

No. The ULKP top bushing is shorter than standard, so these are made only for Slappy Ultra Low Kingpin trucks. For ST1 Classic or Hollow/Low trucks, choose Standard Slappy bushings.

Can I still turn on 100A bushings?

Yes. Turning takes more effort than softer bushings, and you can loosen your kingpin nut slightly to dial in the feel.

What does pre broken-in mean?

Slappy's bushing formula is made to feel broken in right out of the package, so there's no break-in time. They skate the way they're supposed to from the first session.
