The Topgun will not work...completely. You can use the top spacer, but not the bottom. You will only get maybe an inch of lift, instead of the whole 2.5". Most get the CCM top spacer from eBay. It will def work with the Fabtech, although you may want new UCA's as your balljoint angles will be less then ideal.
