Valve spring kit, 4 standard inner springs and 4 slightly heavier 28037460 outer springs. These valve springs are suitable for all 2 valve big twins 1973 through 2002 using 2 springs per valve, including those running B10 camshafts on the street.
Does not fit V700 or early Ambassador using single valve spring. Does not fit small twin V35, V50, or V65 series bikes.
Fitment tip: manufacturing tolerance dictates that sometimes it is necessary to squeeze the spring and the upper retainer in a vice in order to pop the caps (14038000) into place.
