lifting more from 4" to 6" on my 2004 SD

[Alex C]

So i have a pro comp 4" lift kit and it sits level....Its about 4 months old and i really like it but i want just a little more lift because the 35s rub just a little bit when crossing ditches, drainage canals, and shelll rock roads at the ranch. not much, but just a little bit. My wheels are 4.5 backspacing and 18x10s. I figured i could just do the spring hanger/ shackle kit up front to lift it 2-3 inches and some bigger blocks in the rear. Has anyone on here have any experience with that? Will i have to modify my trackbar drop bracket or get a new one to make it work with the additional amount of lift? I know plenty of people that have gone from 6 to 8 inches with the coil spacers for 05+ but havent heard much about wiht the spring hanger/shackle lifts for the 99-04s......any advice would be appreciated.

Oh yeah, and the shocks?

You are on the right track for the front. But check the shocks because you might need to step up to a longer stroke.

On the rear if you are running the ProComp block and factory block then don't just add another 3rd block. Replace one of the blocks with a taller block. You might want to look at a spring also. And check your shocks again.


PM me if you need parts shipped.

Ok on my 99 I have a Procomp 4" lift and I wanted to go bigger because the tires would rub a bit. I put a 1.5" solid steel block under the front springs and a 2" block under the rears. I have been running it this way for about 6 months and had absolutely no probles at all. The tires do not rub anymore and overall the truck looks better In my opinion. The shocks bolted up just fine and the truck rides great just like before when it was only the 4" lift. For a cheap and simple fix, consider the small block under the front axle. Many people are going to chime in and say that "you cant do that" but you can, and I know many people that have done it and had no problems at all. I do about 2k miles per month of driving and have had the blocks in for 6+ months, and had no issues, its proven safe.
Hope this helps.

I'm sorry but you can tell me that you have drove over a 100 MPH and never got a ticket but one day they will catch you.

You should never use lift blocks in the front of a leaf spring truck. It is not safe. And before you ask why I'm saying this... I will ask this question. How many of you have had rear axle rap vibration Now think about the same issue's in the front.

Like I said I'm sorry but it sounds like you know this already.

Ya I know what your saying, but the chances of the axle falling out of the truck is VERY slim. I have done sled pulls and snow plowing, burnouts and 4wd launches and they were all done with the block in thr front. What has happened to others is something to consider, but I am totally comfortable driving my truck every day with the blocks. Make sure you have a new set of u-bolts and put the blocks in and be done with it. If your not comfortable enough to do it then dont, go buy a bigger lift kit. lilredpowerstroke is running a 3-4" block in the front of his truck(or atleast he was last I knew) and hes big in the sled pulling in Florida. If your scared then dont do it, but I dont see the issue with a 1.5" block, I wouldnt put a 4" in there but 1.5" is nothing.
