Bushing Formulas

The first step to choosing bushings is deciding which of our three unique formulas will suit your needs. All of our formulas are made out of high quality urethane, but each one has distinctive qualities which are summarized below - click on the formula name for even more information including weight charts. 

Check out our Compatibility List page to find what fits your setup!

APS™ Formula: Animated Polymer System

APS is our most lively feeling urethane with high rebound and lean. It will turn 10-15% more than the same duro of other brands. It has the widest range of duro from 97.5a (super hard) down to 60a (really soft), and is a great starting place if you're new to changing your bushings. Check out the APS Weight Chart. 

KranK™ Formula: Performance Under Pressure

KranK is our highest rebound formula and has a range from 96a to 84a. It will feel harder the tighter the kingpin nut is screwed on - allowing for customization of feel within the same bushing! KranK will turn less than the same duro of other brands. Check out the KranK Weight Chart. 

WFB™ Formula: World’s Fastest Bushings

WFB's fluid feeling is due to a unique friction reducing lubricant added to the urethane, allowing for fast transitions and 15-20% more lean than the same duro of other brands. It's the formula of choice for riders who want total control over their set up, and has a wide range of hardness from 95.5a to 68a. Check out the WFB Weight Chart.
