The Monomax KYB's are great shocks. High quality, large piston, high pressure, all the good stuff. I put them on my Explorer & I liked them, but the rear rides really stiff. Keep in mind, I like for my cars and trucks to ride stiff, but these were a little too much. I used to be a stocking dealer for them & I talked to one of the KYB reps and he said that they valve the Monomax for vehicles that will be carrying a large load or be towing most of the tim. If you do either of these, I highy recommend them. Be warned, however, if you don't, the rear of the vehicle WILL ride very stiff. If I were going to do it over, I would get the Monomax for the front as they will give you the most controlled ride, and the gas-a-justs for the rear.
One more option: What I'm going to do to my Monomax rears, whenever I feel motivated, is dissasemble them and revalve them. This involves bleeding the nitrogen out of them, disassembling them, buying valve shims, revalving, welding a 1/8" bung on the top & threading on a schrader valve stem, assembling and recharging with notrogen.
Of course, the first is much easier & won't void your warranty....
