Big 3
Real Good quality wire but for the price they shoulda made one of the wires or power wire a little bit longer I have a 2017 f150 5.0 and the power wire was useless, alt was no We’re near my battery for that wire to reach, as for grounds well those reached everywhere only issue was my power wire and yes I know I should off done my research first and see how long of wire I needed but it was my first time trying this and my first attempt and I trusted the lengths that came with kit but I was wrong I guess this kit is made for small cars. So for now I just upgraded my grounds. Until I have some extra money to spend I’ll do the alt to battery but for now I guess this will do cause this wire is expensive. So I can’t say if made a difference.

Big 3 upgrade
The cable and cable lug are great quality. The only this I wish was that there was an option to add an inline fuse to the positive cable. Otherwise it's what you would expect
