3.5" Rough Country lift
37" Courser tires
1.5" spacers
Adjustable track bar
Regeared to 5.13
Adams 1310 driveshafts
Rides great, the 37" Coursers are pretty quiet at highway speeds (much quieter than Noise Grapplers)
Definitely suggest the regear, the 3.8 is a pig with 37's without it and manageable with. You will almost always want to have overdrive off until you hit about 65 or 70 on the freeway. Oh, and if you are a mpg watcher, forget 37's . I get at best 12 - 14 mpg
I am used to driving post 2007 diesel pickups so I am used to 12 mpg 😕
