33's can fit with a minor trim to the front fender. Extending the shackle 2 inches would really screw with the caster angle of the axle. The pinion would be tilting further down and bind like crazy due to the angle.

Lifting it the right way with a set of springs and rear blocks would be the best way to go. New kit's can be bought for a reasonable amount if you shop it right. I got a Rough Country 4" kit with shocks, rear blocks and a raised steering arm for around $250 with shipping a few years back. No Rough Country lifts aren't the best out there. They are pretty stiff compared to other name brands too. But it's what I could afford at the time. It's still under the truck and worked quite well. Best of all, it's proven to be bulletproof. Not one problem, no hokey business causing unwanted wear or crappy handling.

Keep this in mind, the suspension is what's keeping you and your truck connected to the road. Skimping on this stuff is DANGEROUS to yourself and fellow motorists on the road. If you have to save up, to do it right then do so. Everything I've done on my K5 was done on a tight budget, including that lift. Getting such a good deal just sped up my plans and allowed me to do it sooner.
