Default NNBS Bump Steer

I dropped my truck 3/6 with djm arms n been gettin sum pretty bad bump steer. My trip tp work involves 45 miles one way of dips and uneven roads and it can get pretty scary at 70 mph. Is there anything that can be done to remove or at least reduce this ill effect?

Yeah its the 4 inch drop arms from djm but it was too low so I raised it to 3 inch but now the adjustments are maxed out and still out of spec. Will probobly be going a different route with the drop. It rode great at the 4 inch drop setting but tires hit the liners pretty good on an decent bump.

You need to put some 1* bushings in the upper control arms. That way you'll be able to adjust. Anything past a 2 drop on anything but a spindle and you need those bushings to align to spec
