Thoughts on rear replacement shock options

[junglerogue]

My intention is to run Total Chaos UCA's with a coil over shock/spring combo on the front of our 05 GX470. I've been researching and looking around on the web and I found these at Offroad Warehouse: King 2.5" performance shocks with remote reservoir http://www.offroadwarehouse.com/products/sfID1/12/sfID2/1594/sfID3/1601/productID/57700
My question is could I run these with Ironman 660lbs rear springs http://store.camel4x4.com/product/TOY056B.html
Is this overkill? What measurements am I looking for on the shocks/springs? I'm mainly looking to get 285/70's under the fenders and a 2-3" lift. Anymore and I won't be able to pull in our garage. Thoughts and opinions are appreciated. Also, would the Fox Factory Series coil overs work on the front? http://www.offroadwarehouse.com/products/sfID1/12/sfID2/730/sfID3/735/productID/56509
Thanks in advance,
J

Overkill would be determined on what you plan on doing with your truck.

Overkill is a full ICON setup. Kings are only needed if you we're to do a lot of higher speed offroad.

Does anyone have the measurements for replacement rear shocks or front shocks?
