    I need an opinion for my rear suspension. I just installed a 2.5 Superlift system, and even though my blazer sits level it appears to have the saggy butt so I was thinking about installing the ORD zero rate spring to give my blazer a level appearance. I was also wondering if I do install them do I leave out the degree shim. Any suggestions?

    Zero rates are a good way to solve saggy butt. The *best* approach if cost was no object would be to replace the rear springs... but if you aren't made of money, the zero rates are a good alternative. As far as the shims go... if you need them with your 2.5" lift... you'd prolly need 'em with the zero rates installed. I'm not a shim guru, but it seems that when you add more lift (as you would with the zero rates), all else being equal, you'll need larger shims (with respect to the angle).

    The easiest way to figure all this stuff out is to install the zero rates and test drive it. If you are getting some vibes, add the shims, or drop the t-case (or both). Works for me...
