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.

What hardness Slappy bushings should I get?

90A suits most skaters. Go 85A if you're lighter or want a looser feel, or 95A to 100A if you're heavier or want more stability.

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.
