I know I saw this not too long ago but can't find the posts.
I have Silent Armor pro grade on my truck (f250/6.0/crew/sb) and get alot of steering drift so I'm not crazy about them at all. Got them last November and am thinking about dumping them and putting something better on.
I pull a GN trailer - never weighed it but the plate say's 6600 lbs. 21' on the floor, 6' short wall.
Anyway what are you running on your trucks and how are they holding up?
