Hi Keith,
I had them on my 97 before I put the 4" lift on it, and in my opinion they are the best shocks around. They are definatly made heavy duty. I don't know any other shock manufacture who uses a 18mm diameter rod. Even Edlebrock only uses a 12mm rod. I think they will cost you around $200 to $230. I got mine for free as I did the beta testing for them here in the U.S. If you do a search for OME springs, you will find ARBs phone number and they should be able to tell you where you can get the shocks. I just wished they made them for 4" lifted trucks.
