Can someone tell me the better kit for my 98 4 x 4 eb the rear air ride Is out ( big surprise) and I'm about to order the kit but I'm tying to figure out the difference in performance between thes two...it looks like the 90005 has struts for the front and the 90010 has coil overs? Is this the only difference because I thought the 90005 kit was only for the rear but I see 4 struts in the pic?
