1.5" or 1.75" will get you pretty much right on to even out the back with the front. Make sure you get hub-centric spacers (with the lip). Take before and after pictures from the back of your truck, and you'll see how much the wider stance will make your truck look tons better.

 

Yeah no problems here from cjbargains spacers. I run spacers front and back just check out my album on them. I drive bout 100 miles daily and have about 8k to 10k miles on them.

 

I've found 1.5" hubcentric spacers on ebay, should run you about $65 or so.

 

Sorry for threadjacking, but will I need to cut down the exitsing studs?

 

That would be a big negative.

 

Nope, I've got 1.5" spacers on the back and 1" spacers on the front of my Blazer, no cutting modifications required

 

1 more question. With the 1.5, will I run into issues like hitting my tires on the top of the wheel well when my rear suspension compresses?

 

Think that depends on how much weight u add to the back Antman. Look at my album to see how much clearance i have with just spare tire in rear. I havent done any off roading with any flexing to see if and when it will rub. My tires stick out bout an 1/2"-1/4" past well.

 

I love how when i do a google search, it always brings me home I <3 you blazer forum!

I just got a set from cjbargins to even out the back, they do not have a lip tho like the hub does, i didn't think about that when i bought them.

That is the only thing that makes me rethink if i want to use them, but im thinking if i install correctly it shouldnt be a problem..

 

It's not a problem Brian, the spacers on the front of mine don't have the ring on them either, just tighten two lugs togther and it'll center up nicley.
My rear spacers are hub centric and do have the ring, but for some reason the front hubs are bigger and I've had no luck finding hub centric spacers for it.

That being said, I've put atleast 10K miles on them, been 80mph on the interstate all with no problems.
