If you don’t know how wedges work, have a look at this handy diagram from Tracker Trucks explaining every possible combination for Khiro wedge risers:

(Larry Balma, if you’re reading this, we’re sorry for the blatant theft of this graphic, but there’s no way we could have explained it better.)
These Khiro wedge risers also double up as a shock absorber, however you don’t need to worry about a lack of board response: at a solid 80a, they’re not likely to mush out like cheaper rubber shock pads.
We’ve personally measured these at 4mm at the thin end, 16mm at the wide end (approx. 5/32″ and 5/8″), and calculated that they’re approximately a 9º angle.
(And people said we’d never use trigonometry outside of school.)
Finally, much like the baseplates on a set of Bear Trucks, these wedges are quad-drilled, giving you that bit more compatibility/versatility. No matter what your setup is, these wedges should fit.
