Will this fit a 2002 Dyna FXD? Robert Detommaso asked on September 16, 2024

Yes, but this is a custom kit, not a factory bolt-on replacement.

Hi there, can I modify this to use it with a 48 t00th sprocket brake system? Mahmood asked on March 22, 2023

This will not work with a sprocket brake because the max disc width of the caliper is .20" and a sprocket brake rotor is .35".
