This cleverly designed 3/4" front axle really cleans up a set of stock-style HD fork sliders. Beautiful polished 303 stainless caps make ugly nuts and protruding axle-ends a thing of the past. We use them when running our Sani-Trees with HD fork legs, but will also look great on your FXST, FXSTC or FXSTB. (FOR BIKES WITH 3/4" FRONT AXLE ONLY.)
