Wheel hop and steering jitter after lift

[4WD 4RNR]

I just installed the Radflo 2.0 lift along with super flex springs and bilsteins in the rear. Truck sits nice with 285/70/17 bfg at. Problem I'm experiencing is when I hit bumps I get steering wheel jitter or shake. Is this do to the bigger tires? It didn't do this before the lift and also are the coilivers defective?

Did you get the 4runner frontend aligned?

You may have worn suspension components of which the effects were amplified by the lift

Alignment was done, found out it does need uca but when I get them will that correct the problem? Lower arms, ballpoints are good and spider trax spacers are tight with loctite. Is a steering stabilizer an option?
