This is Dodge's solution to the problem that doesn't exist. These kits tie the front wheels together eliminating independent toe in and out. The idea is to cut down on tire wear and death wobble. In our experience this kit will not make up for other worn front end components such as steering gear box and ball joints but it will make your front end feel much tighter and more responsive. Now, we won't put our stamp on it as a fix for "death wobble," but it sure has made a dramatic impact even on our own personal trucks.
The kit that we sell does not include the Mopar damper and we offer the pitman arm as an option. The new pitman arm features an improved angle that minimizes the tie rod angle, maximizing tie rod life. But your stock pitman arm will work if you choose to go this route. If you have a lifted truck that requires a dropped pitman arm, you will not have any need for the pitman arm that we offer because it has stock drop, and your aftermarket dropped pitman arm will work just fine with the new upgrade.
Carli Suspension makes two different heavy duty damper options that we prefer to run with the upgrade kit. Either is a much better option. You WILL need a different damper with this kit since it no longer has the "stud style" attachment point that your current stock one does.
