These work fine, but it's hard to properly rebuild the shock for the slash if you don't use a type of sealant on the rim of the diaphragms. I use the permatex rtv sealant and this fixes the problem. If you don't follow this step the diaphragm fills up with oil once assembled, allowing air into your shock.
