Sold as two bushings, flat washers, and a sticker

APS stands for Animated Polymer System.  This urethane is very lively giving you more turn that a same durometer stock bushing, with lots of rebound.  APS doesn’t compress the same as stock bushings and other formulations, so you can take it from the standard just snug washers to a few full turns without effecting the compression and decompression characteristics.

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.
