I have a 2015 Ram 1500 with about 96000 miles and just had Bilstein 5100 struts installed. They are set at 2.1" with all other suspension factory. Also installed Thunderer 33/12.5R20 tires. I now have a vibration / wobble up to 70 mph. It's worse if truck has sat. Tire pressures are at 40 psi, alignment is good and all suspension parts are tight. Tires have been rebalanced. Could it just be the struts and the setting or just how tires are riding?
