Yes they are. I knew it was true but when I put the ARB in recently the difference was immediately apparent. I keep putting it in gear and wait for the drivetrain to load up but with ARB its just ready to go.
Very coolNot very long..took me a good afternoon to do the entire thing cept the tunnel. The tunnel took the longest but that was first and I was figuring stuff out. You could definitely spend more time on it..like if you wanted to stamp or draw on the leather.
