I have the GT thunder XC linkage and yes the suspension feels smoother in back. When i put the elka on, I didn't have the GT yet, so I rode it stock(linkage) for a while. Anyway, after the linkage went on, all the "bucking" was gone. The Elka helped but linkage helped even more :grin_nod: One of the better mods i've tried. It will lower your qwad a bit, too
