Lift kit and tires
 

I have a 1990 Chevy blazer. I want to lift it either 2 or 4 inches and get bigger tires. Any recommendations on where I can find good deals online? Also, what size tire do you recommend I upgrade to? I currently have 31x 10.5 on there. Thanks.

Is it a zr2? If not then how are you fitting 31's already? Most people need a 4" lift to get 31's to fit.

It's a K5 Blazer. I was told the 31's are stock.

Oh. That makes more sense. As to the K5's I am clueless. Maybe Rough Country has a lift for them? If anything you could probably find a simple body lift and put that on to gain 2-3 inches. And as for tire size, like I said, I'm clueless. Sorry bud, hopefully one of the more K5 knowledgeable guys will hop on and help you out.

Thank bud. I'll look into rough country

I think most popular suspension companies will carry lift springs for it. 33's wouldn't be a problem. 35's with a bit of trimming.

yeah i owned a few k5s a 4 inch lift and 33s. you can fit 35s under there if its just a street truck as they will hit off road but probably be better with a 6inch lift

k5 lift
 

I had a k10 pickup a few years ago. I put a Progressive Suspension 4 inch suspension kit on it and ran 33x12s with ,o problems. Might need to replace your wheels and adjust backspacing, but I had no clearance issues in the front. My truck had a flatbed on it, so I'm not sure if you would need to do trimming back there. With 33s my guess would be no. 35s would have certainly required trimming or a body lift. Pretty much what abig84 said. 35s might work on a street truck with a 4 inch kit, but on my truck I had very little clearance (half inch maybe?) up front at full lock, so even small articulation would have made it scrape.

Lift it
 

Have a 2000, wanting to put a lift on it. 3-4" at what size lift does the drive shaft have to be extended?

With 3-4" of lift you won't have to mess with the drive shaft. I'm almost certain you don't even with the 6" suspension lift kits. Anything beyond that would probably require a longer drive shaft.
