2004 K1500 lift?

[Copasetic]

OK guys I need some advice, opinions, tuff love, whatever you've got. I bought a 2004 Chevy K1500 crew cab about a month ago. I bought a set of reindexed torsion keys for it and want to lilft the rear to match the front. I haven't installed the keys yet but know the truck will sit about level as the keys call for 1-3" of lift. I still want a slight rake though.

I looked under the rear of the truck and seems to me that they have a block from the factory. Now don't flame me too bad but if I were to install a 2" block out back, would I need to remove the factory one? I don't know how the stock block is installed. I know I've seen Ferds with a lift block on top of the factory block so would the same apply?

Would I be better off getting an add a leaf put in or even a lift shackle for the rear? I plan on running close to a 33" tire and don't want it to rub anywhere when I go over a curb or a speed bump. View attachment 87967 I'm also about to remove the 1" zero rates from my K5 so that may also be an option to think about. Thanks for the input in advance!

Hey man, dont know how much help it is, I've gotta 02 gmc Z71 and i just cranked the factory torsion keys all the way up, it made my ride a little stiffer, not too bad, i didnt have to have it alligned, I ran a set of super swamper truxus tires and they wore even. Now i have a set of nitto terra grapplers that are 285/75/r16's as were the super swampers, and also the dunlop mud rovers i ran before the swampers. never had any wear problems, and i ran the dunlops about 5000 miles before turning the torsion keys. I have yet to have any of the three rub. the nitto's seen to be slightly taller than the dunlops or the swampers. the conversion is 32.8x11.2r16 so just about a 33. Like i said ive had it bound up pretty tight and they have never rubbed. plus my truck sits pretty level, still has a minimal rake to it. Hope this helps

It helps more than you know dude. Thanks! If I don't get out there tonight in the garage I may try to mess with it in the morning.
