Sold as two bushings, flat washers, and a sticker
WFB or Worlds Fastest Bushing- is a special formulation of urethane where there is a lubricant mixed in to the urethane. Which is why these bushings will sometime look a little crusty.
The result is an even deeper turn than the APS allows. So if you are looking for a bushing that is supportive but still allows full controlled deep turns, then throw some of that WFB into the mix.
The Magnum bushing shape itself is ideal for Paris Trucks or any Reverse Kingpin truck that has big wide bushing seat. This bushing acts like a thinner chubby, or a full bodied fatcone. It's plump full sized shape increases your resistance to break from center, and has a strong return to center. Because of this most people will enjoy this bushing board side combined with a Canon or Barrel.
