I have a 2019 2500 6.4 with the autolevel, the shocks always seemed to be valved a little soft because the rear suspension would bottom out pretty hard sometimes so I added the top horizontal shock which made a big difference. It doesnt bottom out now hardly at all, almost like it was supposed to be there & like the shocks are valved to be used with the top shock. But by not including that shock FCA saves about $100 per pickup. If your on the fence about ordering this shock, you wont be sorry!
