Wondering how to know which suspension kit to order

Good evening,

Do you have the towing package?

Load leveling is air shocks or struts in the rear. That is not a common option. You would see airlines to the struts if you had them.

If both strut assemblies are to be removed, mark strut assemblies right or left according to which side of vehicle they were removed from to keep from mixing parts.

NOTE:
It is important to note that left and right side wheel speed sensor routing brackets (3) mount opposite each other on the strut making it necessary to install the left side mounting screw from the rear and right side mounting screw from the front.

Remove screw (1) fastening wheel speed sensor routing bracket (3) to mounting flange (2) on strut.
