After cranking my T-bars about 1.5 inches, my truck would continue to bounce after an intitial bounce, especially at higher speeds. I trimmed the upper front bumbstops down to about one-half their original height/thickness. Doing so eliminated the re-bounce. The job only took just over an hour; not a big deal.

Do a test drive on a uneven country road where you would reach near-freeway speeds. If you notice any re-bounce, I would suggest trimming.
