forget autozone,,get KYB shocks.
OME 910. I had some on my short wheel base. They were too much lift and stiffness for me,,I should have gotten OME 911.
910s are good quality and should give you about an inch. OME 910 are progreessive rate alot stffer but still give good ride and handling, I recommend them for your application. I got mine from Rocky Road.
They also make an "expedition spring (OME 938 I recall). They are constant rate and very stiff, made for truck being fully loaded at all times.
