I was cruising along yesterday and had two serious pucker moments within a few minutes of each. Here's what happened:

#1 - I was going about 45 and hit a series of 3 recessed manhole covers in rapid succession. They were recessed about 2" and were within a foot of each other. I should have steered around them, but I've got to say I didn't expect them to upset the chassis as much as they did. The truck ended up bouncing a bit sideways. I was able to steer out of it, but I'm not too certain I want to have that happen again. The last time I experienced anything similar was in a 1994 Jeep Wrangler.

#2 - I wasn't paying enough attention and had to jam on the brakes at 45 mph. The front end seemed to be skipping along the road like rocks on a pond. I'm running 265/75/16 BFG Rugged Trails with about 80% tread. I don't think what I felt was ABS; it was much harder than that. It was almost like the weight of the truck and the extreme braking overwhelmed the traction of the tires. I just read some reviews and the braking performance doesn't seem to be that bad on this series.

Like I said, #1 is easy to remedy. #2 is as well but I don't really look forward to having to brake that hard again. Any ideas(other than the obvious eyes on the road) on how to improve the breaking? The shocks are Bilsteins but I don't know how many miles they have. All 4 are on the short list of things to upgrade soon.

Definitly seems Suspension related , Believe it or not Suspension plays a vital role in braking performance . How many miles on your truck ?

163k. I know the shocks affect braking but I'm not sure to what extent. I wish I had the time/money/tools to try different braking tests with different shocks.

The stiffer the rear travel the more you will slip when bouncing hard. And I believe you did feel the abs but different then what one might feel with different tire makes. Traction and wear rating vary widely. And they don't calculate the differences in tires when it comes to lock-up. some re-grip or break-away better then others and some don't. Just know that if your vehicle is programmed with the correct tire sizes and you felt the abs modulating and you retain steering control all while on some wet road it becomes all about the traction of the tires rubber compounds at that point. Four braking improvement you usually upgrade to slotted rotors and stronger pads. I use power slot slotted (new name is out for them now) and hawk SD Pads. I am crazy on my brakes but they still hold up.

Thanks Sunlit. Is their a tech writeup on programming for tire size changes? The truck came stock with 245/75/16 but the PO went up to 265/75/16 sometime last year.

It is usually done thru a dealer tech2, aftermarket tuner like jet or efilive (efi has a little math involved I believe). There is not much difference in your old to new tires sizes yet to warrant getting it changed. Unless it is free of course. Even your speedo error is very small.
