Rough Country 4" Lift question

Hi all,

I just installed a new Rough Country 4" all spring lift on my 72 Blazer. It's currently sitting about 2" higher in the back giving it an obvious raked look. Does anyone know if the back will settle down a bit over time? Sorry, I don't have a pic at the moment, but I will try to post one later.

Re: Rough Country 4" Lift question

worst lift kit to buy in my opinion . the springs are stiff as hell and dont sag out much at all if ever . there is a reason there crap is so cheep . i will only remove these kits never install them .

sorry for my harsh opinion on there stuff . i have seen there crap way to much and the lack of quality and downgrading hardware size and omitting stuff every other brand of lift kit includes is scary stuff . . . .

my friend had a full rough country all spring kit in a long bed truck . he loaded the box up with cut/split fire wood nice and neat to the top of the cab line and even the tailgate was down with a full load on it . the truck might have come close to squatting maybe 3/4 of a inch . he finally had me pull the kit and install a set of 4" tuff country front springs and new stock rear with 4" flip kit from offroad design and said this truck was not even the same for road ride and offroad flex .

Re: Rough Country 4" Lift question

THanks for the info. I bought this kit about 15 years ago for a project I didn't finish, and I figured since I had it laying around I would put it into service on my Blazer. Hope they were a little bit better made back then lol!

Re: Rough Country 4" Lift question

thats how old or older his kit was .

best you can do is good shocks over the basic lift kit ones .

and try pulling a lower leaf on each side in the rear to drop it some .

Re: Rough Country 4" Lift question

Put some weight in the back and look for a bouncy road to drive down. It might settle.

If not, pull a leaf and see how it sits.

Re: Rough Country 4" Lift question

What if anything have you decided to do?

I have a SuperLift 4 kit we installed in my kids Jimmy it is also stink-bug high in the back. I measured and re-measured and vendor even supplied me with a set of RoughCountry springs which are identical to the SLs. Which doesnt surprise me since they are the same company Im pretty sure.

But the shocks that come in the kit are too short to reach with the springs in the kit, and the driveshaft is WAY too short as well. I am on the fence about solutions.

A) pull the overload and the lower leaf and re-assemble with new spring pin and the angle wedge.

B) Shackle reversal from OffRoad Design and go back to the OEM rear springs.

C) Run a 2 1/2 block with OEM springs. (I HATE blocks FWIW, having all sorts of troubles with them and my own Jimmy back in the day.)

D) Buy brand new 2 1/2 lift springs for the rear.

I hate throwing money at a project, but right now I am leaning towards the new springs. I have Ranch 4 springs on the front of my Jimmy and 4 lift 52 springs in the rear and it is two inches lower from the top of spring plate to bumpstop mount on my truck.

Re: Rough Country 4" Lift question

Honestly, I would be tempted to do the block and run it. I've never had trouble with blocks. Now I'm talking out of both sides of my mouth because I'm running an ORD shackle flip for 4" lift. I think the shackle flip will give you rear spring options galore, and you could combine with a zero rate for leveling if needed. I am running the zero rate to move axle back 1" and I get an additional 1" lift for leveling... I really like the stance.

And on leveling. It seems like every lift I've gotten my trucks squats in the rear. Yours seems to be different. I'm wondering about your spring perches. Are they stock?

And I've never had issues with a rear shaft on a 4" lift. Maybe someone got the wrong shaft before you got the rig.

I think of you get a flip, you might get more spring options for cheaper rear springs. Maybe even free from someone.

Good luck

Re: Rough Country 4" Lift question

Both my Jimmy and my kids have semi-float 14 bolts swapped in from mid 80s Suburbans. I made a jig to move the perches on mine and used the same jig to do his. Both re-used the factory GM mounts. Both have had the perch redrilled to move the axle back 1.

I have the original springs from his truck so we can go back with those. And we might. The block setup certainly the least expensive route.

Since I have 2 trucks setup the same way, it is easy to compare what is and what should be. Because the driveshaft doesnt fit, back of the truck is higher than my truck with 35s and its sitting on 32s, and the shocks that came with the kit are too short all suggest the spring is wrong. Which is the same experience the OP was having.

I like all springs. I will probably just buy some 2 springs, but may swap the OEM ones back in the truck just to take measurements.

Re: Rough Country 4" Lift question

I bought the 2" Rough Country springs. I took the overload and the wedge from the 4" lift springs and made a new pack. The truck is REALLY close to level now. Maybe 1/2" lower than I would like in the back. I may remove the two lowest leaves in the front which are hardly more than zero rates anyway once we get it all together and finalize its stance.

Re: Rough Country 4" Lift question

I think aftermarket springs are made for off-roading. When you load all your gear in the back you don't want it to be sagging. When you are riding empty it's like any other truck with the rear in the air.

Re: Rough Country 4" Lift question

I have a set of 4" springs in the back of my Jimmy I put in circa 1990. They raised the truck 4".... These new springs aren't any where close to 4" lift. Neither pair. Both are HD truck springs. If I climb my 200# up on the trailer hitch, it might sag 1/4". Loaded all of the old parts and spare parts in the back of the truck and it was still too high.

Too high to work with the stock driveshaft and too high to work with the 4" shocks that came with the kit. Something with these springs is whacked IMO.

Re: Rough Country 4" Lift question

I think the first kit I got was Superlift but they don't make that kit anymore so the replacements were the RC. The Rough Country stuff seems to be made just fine. Long term we will see.
