Stiff when compared to what? I think its all in the spring combo you get. OME offers a soft and firm valving which will change the dynamic of the strut. I have the softer valving (OME-90021) with OME 885 in the front and OME 896 in the rear. Both springs are HD rated, however I have a full set of steel RCI skids (front, trans, transfer, fuel tank, a-arm and diff) plus sliders. The HD springs are necessary for the extra weight, as I will be also throwing on steel front and rear soon.

I like the way it drives its firmer than stock for sure but it isn't something that will beat you up. I wanted something that would be comfortable and capable for a weekend rig. If your driving it as a daily your preference may be different.
