Hey little_wiley! Any luck finding the 3 lift you were looking for? I just got an e mail from Rancho, they just released a new lift kit (too new I guess, its not even in their web site yet!) for our trucks ( Ive got a HD2500 Duramax crew cab 4x4 also!) The kit is a 4 lift, however. The part # they gave me is RS6548. They said this part will be on back order for a while due to the demand.

Did you have any clearance problems with your 285s?

How did your new taller tires affect your off-the-line performance?

Are you planning to change the rear drive ratio?

 

Seems that no one currently has a body lift for these HD's and only three companies have Suspension Lifts.

 

  • RCD
  • Superlift
  • Rancho.

 

Both RCD and Superlift are 6" kits.  Rancho's, I'm told, is 4".

 

The BFG 285/75R16's that i have are on Weld 16x8's.  They were rubbing horribly on both front driver and passenger side.  I have raised the torsion bar as a short term fix.  Of course I can feel every ripple in the road now  :0  As far as off the line performance, until you can reprogram the transmission for the 285's, you will lose some performance.  GM will not reprogram for anything other than what they think is appropriate and 285's are not on the list.  You must have a reprogramer like the "Hypertech" product except that they do not have one for the diesel HD's yet just gas.  Their diesel version should be out by the end of the year.

 

We have a "4 Wheel Parts" retail store here in Jacksonville.  They carry and install both Superlift and Rancho.   Installion is free right now for the superlift kits.  So I suspect that I will go with the superlift kit.  

 

What expierience has anyone had with the superlift products ???

 

As far and chaning my gearing, I will not be going larger than 285 or 305's and should not have a problem with the 3.73 gearing.  Just don't know at this time.  Have already put way to much money in the this truck. :D

If you're not going any larger than a 305 or 285 it might be time to rethink which lift to go with.  A 6" lift with 33's on a HD is going to look like you put your factory 245's back on.  I myself am waiting for Rancho's 4" kit and will probably run 295's in the summer and 285's in the winter.  Just my opinion, but for a 6" kit go with 315's.

There is a body lift made for your truck but I would strongly advise not to put a body life on your truck.  Why put your truck body on stilts and put more stress on joints not designed to take this extra harmonic forces.  But that's just my opinion on the matter.

I've checked every where on Duramaxes there aren't any body lifts available on it or the 8.0. I guess the engines weigh too much. The one i'm saving for is the Rancho 6 inches is just too tall for my liking. I think w/ alittle trimming you may be able to get 315s under a 4 inch lift.

Pics in sig.  2001 2500HD CC 8.1/alli with 3" b/l and 295's.

Performance Accessories states:

The reason that no lift is available for the Dmax is the possibility of having to re-plumb the intercooler which would void the warrantee.

 

They are by no means saying that their current kit won't work, its just that they have not gotten their hands on a Dmax to make for certain that it will work.

TXDMAX, I have a Performance Accessories body lift the kit number for the crew cab HD's is 183.  I also installed the gap guards which I highly recommend, since they actually keep alot of dirt out of the engine compartment.  I've been running the b/l since October with no problems.

      Manufactuer's Defect - Paint Failure - Cherry Red High Country 2021 Suburban

      By AlVeron · Posted

      This is NOT impact damage nor neglect. There were previous class action lawsuits because of such paint preparation st GM manufacturing plant. Not just the Cherry Red Color. This paint is applied in three processes to obtain the desired color.  The manufacturer will cover for 36 months or 36k miles only. That rust is actually corrosion because of the paint process failure. Corrosion is covered for 100,100 miles or a certain months. However their corrosion doesn't include this type. Go figure. Clearly manufacturer knew from previous paint issues. This started 3 weeks ago out of the blue.

      Is it time to put a piece of tape over the CEL?

      consider doing electrical testing?  I would guess some power or ground wire/connection has a problem.   alldata.com has wiring diagrams, connector pinouts and diagnostic procedures you can use to find where the problem is.

      My First Project and GMC has me stumped

      By davester · Posted

      can you tell if the reader is actually trying to get codes, and the pcm is reporting none, or is your reader just silently failing because it's not communicating with the pcm?

      Any joy with this truck seems to be short-lived.   The CEL for P0172 ("bank 1" too rich) is now "intermittent".   I'm not sure where to check, or re-check, and my energy to keep chasing problems with junk is wearing thin. The P0172 seems to set as I'm coming to a stop, completely off the throttle, when fully warm. At least, that's what it's done the 3? times it's set.   Everything appears normal on the scanner EXCEPT long term fuel trim. There's only one bank on this vehicle because it's an OBD 1.5 with only one upstream O2 sensor. At idle, it's around -16.4% and will dip to -18% occasionally at idle or off-throttle. LTFT approaches 0 when throttle is held at 2500rpm. Short term appears normal, much closer to zero all the time. The LTFT tells me the engine is running rich at idle but compensating at higher load. But, why?   The EVAP purge valve doesn't appear to be leaking/sucking fuel vapor continuously. Is it sticking just as I come to a stop and the engine is choking on fuel vapor and sets the P0172? But that doesn't explain the persistently negative LTFT. Disconnecting the purge valve doesn't seem to make any difference.   I suppose that leaves another dang issue with the fuel injector. A leaking fuel pressure regulator, a new leak in the spider, or a leaking fuel injector/poppet valve I didn't see, or a small crack in one of the spider legs.   The vacuum line leading to the fuel pressure regulator doesn't have raw fuel in it. It doesn't even smell like fuel when it's pulled off, not until you suck air through it, then you can tell it leads to a fuel component. I'd consider that normal? Nothing is signaling this is a FPR issue from the outside, at least.   The oil smells like fuel but it's not building volume. I've noticed most oil in most engines smells like fuel to some degree so it's hard to say if the smell is an issue or not. Or if the engine just still smells like fuel because the crankcase was full of it a few hundred miles ago. But it's been changed twice since that original issue of the leaking fuel line dumping fuel into the intake.   Patience is running very thin. Every win seems to be accompanied by two steps backwards, or another issue that leads to removing at least the top half of the intake manifold. Enough! LOL
