Its hard to tell from the pic it looks to be dual rate but i can see in the pic the sleeve between the lower and upper spring (if it has 2 seperate springs they are dual rate)..upper spring is mainly just ride height it does get use on compression though(downforce)...ordering them unless brett (king shocks) got the weight of the car they are not going to work right out of the box actually ones made exactly for a car dont without testing and adjustments but anyways if you call brett at king shocks they will definitely assist you in setup...he did my offroad truck and I gotta say the best shock and support for desert racing!!
Also you you can slow the compression down on the bypass shocks to help it from bottoming out!!
take hywy 372 off of 160 in pahrump take to baker turn off go left .. its a little over an hour depends on how you drive or what your towing just out of pahrump road gets tight with turns..
he may be refering to the diameter and not the width if the diameter is smaller in front or vise versa the tranfercase may have issues one set spinning faster than the larger tire
We use Alpha liner for jobs here @ my work ..they do a great job , priced fair also, ask for Matt
