Suspension Performance Question

Alignment is done every few months... It's aligned.

I am curious what I need to do to make my 4Runner able to handle washboards better than it can now.

Currently with the BOSS Coilovers (550 lb), OME 890's, and Bilstein 5125's, and 285/70/17 Duratracs, I cannot go over washboards faster than 5-10mph without losing a couple teeth, and nearly flying off of the road. Even around corners on the freeway if I hit a series of potholes or just a rough section of road it feels like I may hop off the road.

I need this to not be the case.

What do I need to replace in order to fix this? Is it the coilovers? The springs/shocks in the rear?

Any help appreciated...

If you can lower the ride height up front some, that will help. Part of the problem is that the tires you're running are probably a load range E and have very stiff sidewalls. Try lowering the tire pressure some. The rear springs you have are a good spring rate, and the 5125s are about as good as you can get unless you want to jump up to a 2.5" Diameter shock.
