If you already have the shocks, check with say Rough Country or someone similar. RC has a set of 2.5" springs for 199. You could PM member Rockridge 4wd and ask for a quote on them. They(Erin) will hook you up with free shipping and 10% off so even after taxes and "shipping" you're still below 200!!
