Harder KranK durometer bushings (93a) are for heavier-weight riders (over 140lbs) as harder durometer bushings allow for a nice tight set-up
Softer KranK durometer bushings (87a) are recommended for medium-weight riders (75 - 140lbs) and they are also for those looking for a looser setup in the RoadSide position when coupled with a harder duro bushing.
Excellent when used as a TallBarrel/TallFatCone combo - but incredibly fun and variable when used in the Roadside position in combo with other shapes & or duro's in the Boardside position.
Not sure what size bushings your truck will work with?
What combo bushings to use? Which Formula to choose?
