This is the stiffer CX bushing set up = one cone and one barrel bushing. If you want the best lean and turn these are the real deal. This combo is the fast pump go to bushings. The APS formula has a real nice snappy bounce back that gives you momentum. The barrel lets you agressively pump, it is stable, and the base allows short fast pumps that get you to a top speed. We also sell a Krank version (less lean) and also a stiffer cone with barrel kit. 

APS stands for Animated Polymer System, and as the name implies, this compound is very lively and offers high rebound with lots of control and lean.  For the same durometer, the APS will turn 10% to 15% more than the same durometer of other brands.  In addition, the APS does not change much when you tighten the kingpin nut past snug.  RipTide recommend tightening to the point where it is difficult to turn the bushing in the bushing seat by hand.  Use a flat washer for more resistance and a cupped washer for even higher resistance.
