09 Gear Change?
I bought an 09 F350, 6.4, crew cab, swb, 4x4, AT, 6" lift, 37" Toyo's, 6000 miles(yes 6000) & 3.55 gears. I'm thinking the best gears for this truck should be 4.11 from all the charts I've seen but wanted some other input. The door pillar reads 275/70R18E for the stock tires.
I also want to put lockers in the axles when I change gears, I like the ELocker but the warranty is void if the tires are bigger than stock. I'm leaning towards the Trac Lock front & back, the front would only be working when the hubs are engaged anyway. I've read that the ARB's sometime have oring seal problems. Any input would be great.

Everyone and every situation is different, but since you asked...
If it were me and I wanted selectables, I'd get ARBs. If I didn't care about it being selectable it'd be Detroits. If I wanted limited slip differentials (LSD) it'd be True Tracs.
