Sold as two bushings, two 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 Tall FatCone Bushing itself has the same break from center as a barrel bushing, with a progressive resistance as you dig into a turn, and a little higher return to center than a standard barrel.
This is a great bushing if you are trying to get as much lean and turn as possible but restrict that last bit to avoid wheel bite.
As always play with your bushings in different combinations to work out what feels great for your current level.
