Part Description
Black Contrast Cut
Text excerpt from the catalog:
The 2006 thru 2017 Dyna models come from the Factory with 11.8" (300mm) diameter front disc rotors. To allow installation of 11 1/2" (292mm) PM Image series or discs PM created a special version of their popular 137X4B caliper. When you want to keep your stock size discs but want PM calipers for perfect looks and improved braking performance you can use ZPN721433 and ZPN721435 calipers, as these will work with your 11.8" (300mm) rotors.
