I don’t know how?
Anyway, I wasn’t gonna argue with him, but it just threw me for a loop.
Any insight from the expert on here?
Maybe it’ll be useful info for somebody else doing the upgrade on their truck.

Makes me wonder what state his rear brakes are in. Maybe they cam over before they can lock up. ;-)
