well, you can't fit 37's under a 4" without some trimming and you'd still have rubbing. I have 36's on a 4.5" and i rub a little. About stretching to a 6", i'm sure you could do it if you pieced the right pieces together for it.

could you... Yes

But you have to check and make sure it dont throw off your steering geometry off

As for the blocks in the rear, its not a good idea to stack them. Just buy one larger singe block.

yup, you could, but your front end might be off, your steering may be off. There are components included in a 6" that are not included in a 4".

There are a few guys on here running 37's on just a leveling kit with no rubbing. You can run them with your 4" lift. The issue isn't as much the lift as it is the width of the tire and offset of the wheels.

If your 4" lift included a pitman arm, you should be able to add a 2" spring spacer (leveling kit) to the front and then change shocks. If not you may be able to also add a pitman arm from a 6" lift kit. Not knowing exactly what lift you have makes it all a guess.

What you do out back will depend on what your 4" lift included. First, your 4" lift probably only had about 2-1/2" in the rear. They do that to level the stance a little. If it was raised by a block I would not recomend a taller block, 3" block is the most I would run personally and people generally say 4" blocks are the limit and you should use traction bars if you go that high on just blocks. If your 4" lift used new rear springs or an add-a-leaf you should have no problem installing a block for 2" higher.

I have the 4" Rancho lift on my truck and it has been a great lift since I bought the truck. the lift came on it from the factory. I have put some abuse too it and it still is staying strong. I switched to a 6" ICON block out back and installed a 1" ICON TEI spacer to add some height. The truck still sits the same and gives me a taller stance. For the money, I dont think you can beat it, but I know there are lifts out there that are better quality like ICON, Rize, etc. I have some bolt on OUO traction bars on the way to add to things.
