you may want to rethink your spacer size since the fj springs will add lift by themselves. also, you do mean fj springs & shocks, right? or do u want to use the springs with the stock 4r shocks? if thats the case, why? either use just the spacers you stated by themselves, or get the whole fj setup & use thinner spacers. then again, if your looking for a three in. lift, just get the toytec .
