But common sense would dictate you don't add OEM parts to an aftermarket system and expect it to perform properly. Or perhaps that's too hard for you to understand?

 

Im not sure if there is anyone on here with just a 6in lift and 37s but this is what I would do: I would get the 6in lift with the 37s and see if it is REALLY bad. I will probably rub a little but I am not possitive. Those hulks should help out wince they have a good amount of backspacing. So if the rubbing is really bad then get a spacer and a block or an add a leaf. I have definitly seen this etup on our trucks and it looks great.

 

There's a guy on here running the 6 inch fabtech and 36 in. IROKS on a regular cab. They look like they fit just fine. For the rear, he was saying a 3-4 inch block with the add-a-leaf will be the same as a 5 inch block. The less block you have the better, I'd recommend the smaller block and the AAL. With 37's it would definitely be a tight fit but you could probably get away with it for a little while with some trimming of the front valence and fender flares. Just don't go offroading you know... A lot of your rubbing issues will depend on the backspacing of your wheels. The closer to stock, 5.5 I believe, the better off you will be.

 

It all depends on your wheel backspacing' 37's on a 6" lift can be done. I have seen it personally on a couple of trucks. You may have some rubbing, but it should be minor. I say go for it.

 

I have a buddy that is running 37x12.50x17 BFG muds on 17x8 951's. They might be 10" rims...not sure. He also has the procomp lift...he has some rubbing at full turn and hitting a bump/dip.

EDIT: My local shop is going to let me test fit my 2 front wheels with the new 37x13.50x18 ProComp Extreme all terrains. I'll post the results...just not sure when I will get around to it...I've been super busy lately.

 

Kinda like using the stock MAF sensor with an aftermarket intake. I mean, who likes a heavy wallet, it's "common sense" to spend a load of cash on a new one...good theory!

On a serious note, I think I'll go with the 37's and take my chances. I'll make sure it's driveable before I burn those stock tires to shreds

 

Nice false analogy. Nothing like comparing mechanical components that physically CANNOT be put together to a computer controlled sensor that is more than adequate for an aftermarket intake. It's a commonly accepted fact that the stock MAF allows plenty of airflow for most modifications. You don't see any benefits changing to a larger MAF unless you supercharge. And then of course you have to get new injectors as well as a custom tune. And, from your last post, from the amount of money you've been pouring into your truck, and the fact that you own another truck as well, tells me that your allowance makes your wallet far too heavy.

 

I don't own the green truck, or else I'd be getting that one stuck instead of my baby. Bad analogy? Most lifts reuse the front coilovers...smartass.

 

Well I was referring to the compatibility issue with the stock blocks versus the Fabtech 4" blocks...but nice segway nontheless. Now for a perfectly innocent question - You don't plan on racing around like you do now once your truck is lifted do you?

 

PS: Remember SalFX4 is running a 2.5" kit and 37s but he is using the Rancho lift. Reason, I say this is look at the angles of a Procomp and Fabtech lift versus the angles of a Rancho lift. Before I added the spacer, my angles were all just like stock and now my angles are more so like the Procomp and Fabtech lift and I gained an inch over them.

 

I have a buddy that has the fabtech 6in lift on his 04 f-150. He is running
37-12.50-17 tires on the factory wheels. NO RUBBING WHAT SO EVER. I guess if the back spacing is right on the wheels you should be ok. I was with him when he got his lift done. He has nothing extra, just the fabtech lift kit.

 

What tires?

and it surely helps that the stock wheels are only 7.5" wide. I hope he doesn't plan on using it. .

 

Josiah,
are you installing the lift? If so I would suggest buying the 1" spacer up front from someone you can return it to, the same with the add-a-leaf. Then you can put it together without the extra parts and if it works with trimming, you can return the parts and save it for the body. If it doesn't you can throw in the spacer and add a leaf. If you are having a shop do it try and find a truck suspension shop and see if they re-arch your springs with an extra leaf this should solve the rear.

I am kind of in the same boat. I may get a lift and let it sit around until I can complete all the other stuff to give me a safe and functional ride.

 

Unfortunately I don't have that available to me. I am installing it myself, I've done a lot of work on my truck to this day so why not. As for the leaf springs, thats a good idea and I plan to do so, I may just buy the adj. coilovers, god knows I need it.

 

Josiah, just curious but what do you do for a living? I'd say you have 3 options. 3" body, DL coil-overs, or just the regular shocks + a spacer.
