When I put my OME HD lift on with JKS frt and rear adj. track bars, would it be wise to go ahead and weld on some washers to add thickness to the bracket and help prevent wallow if it becomes a bit loose between re-torques?

 

Shouldn't have to at all. Maybe a little loctite, but that's it.

 

IF the bolts are tightened to the appropriate torque, you should be fine. An easy way to keep an eye on things is by getting a paint pen and marking a line off the head of the bolt to bracket. That way, if the line separates, you know you'll need to re-tightened the hardware.
