Well I finally got my truck back from the dealer (4 weeks, long story) after having the Stage I Ram Runner suspension install which is basically the Kore Prerunner suspension. I am runnning 17" ATX with 35" Cooper Discovere AT3's. If I accelerate at WOT from a complete stop I feel a temporary shudder, which disappears at 20-25 mph. If I hit WOT at any other time, nothing. At highway speeds it rides like a cadillac--no shudder or wobble. If I hit WOT on the highway it kicks down to 2nd and goes and goes. Also handling and cornering are vastly improved.
Before the upgrades I didn't have the take-off shudder issues, maybe a little wobble at 70-75mph which is now gone.
Could the TC or some other driveline component be acting up with the weight of the new wheels and tires? I have a non-stock rear swaybar. It wasn't removed with the Kore install. Could that be the problem?
Any advice or theories when be helpful. Thanks.
