Riptide is a skater-owned microbrewery-style company that produces hand-crafted urethane compounds in small batches right in California. With close inspection at every level of production, the Riptide crew specializes in custom bushings to fit any truck on the market for a superior feel. Their bushings come in a wide variety of formulas including APS, WFB, and KranK for different riding styles and demands. See below for more info on each formula or check out everything from Riptide here.
APS™ Formula: Animated Polymer System
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. We recommend tightening to the point where it is difficult to turn the bushing in the bushing seat by hand. Use a flat washer for lower resistance and a cupped washer for higher resistance.
WFB™ Formula: World’s Fastest Bushings
This compound has a unique lubrication added that does not bond with the urethane which is why you will often see a white residue on the surface. This compound offers reduced bushing friction for fast transitions and a deeper lean than the APS. WFB will turn 15% to 20% more than the same durometer of other brands. WFB also offers lower rebound than APS and is designed for the rider that wants a very fluid response. Truly the bushing of choice for the more experienced rider that wants to control his bushings instead of the bushings controlling him or her. Like APS, the WFB compound does not change much when you tighten the kingpin nut past snug. We recommend tightening to the point where it is difficult to turn the bushing in the bushing seat by hand. Use a flat washer for lower resistance and a cupped washer for higher resistance.
KranK™ Formula: Performance Under Pressure
Our highest rebound formula to date, KranK is designed specifically to change under pressure and is controlled by the amount of clamp pressure you subject it to when tightening the King Pin nut! The effective range of control is from barely snug for the loosest feel to 2 full turns for the tightest feel. KranK will turn the same or less than the same durometer of other brands which is also a departure from APS and WFB. As for washers, flat washers work great with this compound, but for the greatest control and range of this performance feature, use cupped, precision flat or precision cupped washers.
