This upgrade kit can be used to convert any 2015, 2016, 2017, 2018, 2019, and 2020 Cabrinha bars (both recoil and trimlite) to a Fireball connection. This will NOT work with the modular bar.
The process is a bit tedious and might require some extra parts on heavily used bars, as some connections might be too tight to take apart without breaking.
Check out this video for all the required steps:
(Hint: If going back to the chicken loop is definitely not an option, for a much simpler installation, just break the top half of Split Spinning Handle off the old bar. Please note that you will not be able to find a replacement for this part in the future, so it will not be possible to go back to the chicken loop configuration with this method).
