Per AEV's website: "This suspension and spring/shock tune was designed for the gas engine Gladiator, so EcoDiesel-equipped vehicles may not achieve the best possible ride quality and load carrying capability". May not usually = will not!!!
AEV kit is less than rec with the diesel-- that's why they are creating and in final testing of a diesel specific kit. That is per AEV (by the way), not me!
Waiting for the diesel specific version of this kit to come out (should be soon now)-- I've had this kit on three different jeeps in the past with zero issues. Agree that the ride/handling is way better than stock. Way less dive in corners and braking and more stable at speed.
You have a tough ? I will tell you this though, I just got my Gladiator Rubi diesel and have had the gasser in the past... the diesel engine is phenom!!!
Buy the kit that matches what you do with the vehicle, not the other way around. I.E.-- if you spend 80-90% time on-road, not off road, don't buy a kit for the opposite.
