In about 6 weeks, I will be driving my 2022 RAM 1500 ecodiesel up the AlCan highway doing mild off roading as I go. I've replaced the 55 series tires with 70’s to gain more sidewall and went to 18" wheels from the stock 20” rims. I spend a lot of time on old gravel roads, and have found the stock shocks pretty stiff causing the rear end to dance around on washboard. If I replaced the nearly new OEM shocks with Bilstein 4600 shocks, would that help in off road situations? How will it drive on road? Thanks in advance, I don't want to spend the $ if it will do nothing.
