Priced as two bushings.

Venom Keg bushings are tall bushing.  

You would want this bushing if you wanted a slightly harder to break from center than a barrel with a high return to center feeling.  The cool part is that as you lean more into your turns, placing more weight on the rails the resistance grows until it stops, but it does this in a more gradual way than a stepped bushing.

Ideally used on your board side because of its influence to already add resistance to your break from center.  

Remember, only for tall bushing revers kingpin trucks.
