Bones only puts out the best. And with minds like Kevin Reimer behind the product, you know it was extensively tested. The hard insert reduces hanger play, which basically makes your trucks perform better in every way possible. To gauge for consistent stability, anticipate to ride a softer durometer than your previous bushings. They are sized to fit all longboard trucks that matter.
Here's what it says on the package, and they don't appear to be lying either:
-Patented bonded-insert technology
-More precise steering
-No break-in period
-The BEST bushings, period.
Venom is hyped to introduce a new shape for trucks that use Tall Bushings. The ‘Keg’ shape is designed to give more progressive resistance and rebound than a barrel, but without the hard stop of a normal stepped bushing. The curved side profile provides extra meat while still fitting most bushing seats. Ideal for use on the board-side, especially if you want to go to a softer setup without losing stability. Just think of it as a barrel, but with that thicky-thicc-thicc as Nelly would say.
