Chubbys offer the highest stability of all the shapes discussed here and work best in a truck that has a stepped bushing seat to take advantage of the secondary step in the bushing, the vertical side wall and the large backside of the Chubby. They still turn very well and can be used in a softer duro if you are looking for a stable yet plush and comfortable setup. The Chubby is one of our most versatile bushings because of its size, shape and wide variety of applications.
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.
