Riptide Fatcones give more and earlier rebound because of the fatcone shape. Fatcones have a regular barrel width on the top, and a wider (fat) width on the bottom.They are a great boardside bushing for ldp trucks. Some skate them boardside and roadside in an hourglass configuration!

They have a little less rebound as Seismic bushings. Riptide bushings have a more fun feeling to them :)

They come with two fatcone spare washers to add to your collection of fatcone washers that you will likely never use xD
