Much better than stock Review by Wheelie 3
These cables are made 10x better than stock. Im glad that I changed them, because one of my boots on the stock set was torn. Haven’t had a chance to take them on a good ride yet. But will soon. DK ROCKS!! (Posted on 7/13/2023)

10.4 fatty wires … Review by Garry
Fit is perfect, wires work excellent and look great as well… tip, look at old wires where they have rubbed, put wire Loom over those areas on new wires for protection or the fatty’s will for sure rub Thur!!! (Posted on 12/19/2022)
