Never put blocks in the front. Although I've used them I do not recomend them for the rear. Does you truck have leaf packs or coil springs? Is the front axle straight or IFS?
You can build your own leaf packs or alot of places will build them for you and then buy every thing else you need.
I did a coil conversion on my jeep a few years ago and the last few months me and my brother have been modifying bigger axles for the front and rear. For now we are putting an SJ AMC Corprate 20 rear and Sj Dana 44 front. As soon as I can get a nice Dana 300 Transfer case were gonna go fullsize Dana 60 rear with a fullsize Chevy Dana 44 front with 4.56 R&P.
