Again , a rear track bar . No adjustability means you'd have to luck out for the axles to line up . Running both also helps eliminate bump steer though , I've been experimenting
, not the cheapest route and takes a minor mod to the track bar to work .
Extend the rear end links if your running the sway bar , it takes alot of stress off the frame mounts . Confirm the front ones you have are adequate for the lift .
I'll say the same for the upper arms on your list , get the super flex and help reduce the stress on those fragile mounts too . Upper mounts have broken before .
KOR steering brace is another nice add on . It really reduces feedback in the wheel .
Personally , I like the 32's at 5" . No rubbing , no cutting , decent fuel economy and like everything else listed on my list , less stress to the powertrain . At 33 , I would got 10.5 , not 12.5 . No preferences on which brand .
Some do , some don't encounter vibes when going higher . My jeep had a 1 inch trans drop when I got it . I still run it and have zero vibes at high speeds . Not sure what tcase your running , but with the 249 , no driveshaft had to be replaced or altered from stock on mine . Try the drop if you have any issues , homemade is a really cheap fix .
