I bought something like that, a split bearing retainer at Miller Bearing in florida. I was looking for something to lift my wifes xj just a inch or so with out taking the front apart. I found one that had an 2 1/8 inner diam and 3 1/4 outer and was .75 inch thick. Just compressed the spring, slide down the isolator, and put the two halves together use the bolts to hold together, and tack the halves together and release the spring. Cake. And added 1.5 to her 3" lift. Can find these split bearing retainers in just about any size they say. $9 for each side. I'm a junior achiever in the cheap xj world...
