Just like their big brother, these Sporty axle adjusters solve all the problems that plague the axle adjustment area of your swingarm. No longer will your tube crush, the plates will never again collapse and come out of adjustment, and corrosion is a thing of the past. We even jumped up to a 3/8-24 stud and nuts. Fits all Sportsters from 1979-2003, as well as four speed shovel head models, and many other models of the era. Adjustment blocks are black oxide, studs are stainless steel, and nuts and washers are high quality chrome. All 100% Made in USA of course.
