I wish this kit contained the compression elastomers too (which are ticker than the rebound). Instead, they give you two sets of rebound elastomers to choose from, the red are hard and the yellow are softer. The bolt heads have a moon-shape cut out of them, which fit the low-rise Fasst Flexx handlebars. I have the high-rise bars and my stock bolts have a full round head, so I don't need the cut bolts (not that it really matters). Ideally, I'd like to see Fasst Flexx specify which bolts are included in the kit and I'd like to see them release a kit with a full set of rebound and compression elastomers.
Here is what I know... I wrote Colt Brinkerhof of the Fasst Flexx company and he recommended Rocky Mountain ATV because Fasst Flexx company was out of stock at the moment... He took my information and recommended the 15 degree ATV bend bars for Dune riding... And as always... Rocky Mountain got them to me in 3 days!!!
He also recommended the elastomer kit to help fine tune the bars to my liking!
