95 Tahoe 2dr 4wd currently has Rancho RS5000 front and rear shocks installed. Shocks have been on the truck since i bought it about 4 years ago and i think its time for new ones. I get a hard back and forth sway in the rear at speeds around 65+ MPH. Truck has a 3 inch body lift with 33s. Any rec. on shocks or just replace those with some new ranchos? Also, do the shocks need to match the 3" lift as well?
