Anyone know anything about Black Diamond Shocks? I need new shocks for my truck, and I have a dual shock setup, so I will need 8 shocks. I was just browsing eBay and came across this set. http://cgi.ebay.com/ebaymotors/BLACK-DIAMOND-SHOCKS-CHEVY-PICKUP-BLAZER-SUBURBAN-NEW_W0QQcmdZViewItemQQcategoryZ33590QQitemZ8030897394 If I just bought two sets of those shocks, it would work. Any good/bad news about these shocks? I'm such a newb. I have a 4" lift and these say they work for 4" lifts. Rip off or not?
