I have not put these into service yet, so I can't speak to performance or durability yet.However I was extremely impressed with the fit and finish on these gearboxes! They look great, appear to be good quality, feel like they are very tight (no slop), and are fairly heavy.I will update after running them for awhile to see how they perform.
