2004 GMC 2500HD FENDER HEIGHTS


Recommended Posts

Posted

OK guys - need some info. I've got a 2004 GMC 2500HD EXT CAB 2WD that I bought used. It already has 285/17-16 tires on the factory wheels and has the following fender heights:

 

front 38.25

rear 40.75

 

Both sides are almost perfectly even side to side.

 

Now, I want to simply bring up (level) the front while mataining the ride it has now, which is actually really smooth for this type of truck. I compare that to my dad's 2002 Chevy 2500HD EXT CAB Duramax. Anyway, with the fender heights like they are, when the larger tires where installed, the front was probably cranked up at that time??? How would I know this?

 

I have cranked it up an additional 3 turns and was able to get 1 inch. There's plenty more to go on the passanger side, but the driver side is already within the channel. The added 1 inch would be fine if I'm sure that it's not maxed out. The ride wasn't that bad with the 3 turns either. I've lowered since until I have more info. I'm thinking of cranking it up, adding Pro Comp ES9000 extended length shocks up front and regular ES9000 out back and an alingment. What does the masses think about that as far as problems down the road? I know that ride quality only I can judge, but being new to GMC ( former FORD man) I don't want to spend a lot in a lift when the truck is my cadallic & daily driver & will probably never see off road duty. Largest thing to tow will be a 33hp tractor and 21ft Boston Whaler.

 

Other option I was considering, was the FABTECH 3" lift spindles. Looks like a fairly straight forward install, but around $500. My wife & I have a child on the way :thumbs: , so that's the reason for the "CRANK & SHOCKS" approach.

 

Thanks in advance guys!!!

Do a search on "ford keys" or "torsion bars", there are about ten threads on this subject, and as for your other post try "intermediate steering shaft" that will be your answer there for sure. There is also a great PM on the light duty site for lubing the shaft for a temporary fix. There is now un updated version of it, and your 04 should already have it.

Thanks!

 

That's a good looking truck you've got.  What have you done to the front end of your rig?

 

 

 

 

I cranked the torsion bars up 1-1/2". I still have the factory shocks on so I did not dare go any higher. I went 2" on my previous truck and overextended the shocks. I think Rancho now makes a shock that is 2" longer. Up until now the shortest I could find was 3". My wheels are 16X8, and the tires are 285/75's so I had to do some trimming on the lower valance. Not much though.

"My wife & I have a child on the way :thumbs:"

 

Congrats man! Good times ahead.

 

I have 255/85s (33") & just cranked the bars (careful to not overdo it) & added bilstein standard length shocks. Works just fine. Only had to trim the lower valance a little bit.

Thanks Guys!

 

Yeah, the wife and I are looking forward to it. First one!!! :D

 

sstimothy, What are the heights from the ground to the center of each fender front and rear on your rig? Since it's about the look I was wanting, that would give me a guide to go by.

 

Thanks again!!

Probably want to go with the green GM keys instead of the Fords on your 2500 HD. The "green" keys are originally intended for 1500 trucks but are made of the same metal and have about 20* more downward indexing. You'll probably get around 2-3" of front lift out of them.

 

The Ford keys are what 1500's use to bring the front up. Out of those you'd probably get about 4-5" of lift out of the front and that's going to put a big time strain on your front end components and CV's. I'd suggest sticking with the greens and make sure you get the front end aligned when you've finished.

Thats exactly what I opted for. I found a set of slightly used fabtech spindles on ebay for about $150 shipped and threw them on.

It brought the overall hieght of my truck 1" taller in the front when compared to the back.

Thanks guys for the replys thus far, .........but come on. There's got to be more owners out there that can give me some fender heights, front and rear, along with how they accomplished the leveling. Help a brother out!! :driving:

I will make myself a reminder to do it tonight. Take into consideration that I am running 285's so I will try to measure from the center of the hub too to give you a relative figure just in case you a running a different size of tire.

Posted

Front: 42 3/4"

Rear 43"

 

Cant tell a difference by looking at it that it has 3/4" difference.

 

I just put in green keys and barely cranked them.

well, I dont know how much help this is but mine is 47.5" from ground to fender but I have a 3" lift spindle, 3" body lift, gm Green Keys, and 35" tires.

I just read your original post and I guess you are running the same size tires as I am. Like I said, I cranked the bars up one-and-a-half inches. Fender heights are as follows:

 

front (from ground to top dead center of fender) 41"

 

rear (same) 41"

 

The ride quality is still good in the front and the rear is still all stock. Hope this helps.

I just also purchased some used spindles. Could you give me a small brake down of how you installed them.

    • Getting greedy...   The AC pump has been replaced at least once per service records, and it's been recharged twice since 2018 or so, in approximately 2 year intervals between those charges.   It was done at the same shop...clearly they were enjoying the revenue of recharging the system periodically versus actually tracking down and fixing the leak. I learned that the owner was 88 years old when she passed in 2023, so maybe they assumed only a temporary fix was needed anyway.   The system is basically empty now, the compressor spins freely, so I'm guessing it "just needs a recharge".   I vacuumed it down, and it has basically held overnight. Doesn't appear to leak under vacuum, check! So it must leak under pressure. I don't have a way to pressurize the system and pressurizing it with shop air wouldn't be great for the air dryer (which is probably toast anyway?)   The dryer (accumulator? I'm not an AC expert) has a Schrader valve, but the high side has an old ball-type valve, which are notorious for leaking. It's clearly had schmutz blown out of it at one point because the line/area next to the valve is coated old black crud, which I assume is AC refrigerant residue/oil, or maybe even dirty dye. I think I'll roll the dice and replace the valves. I have a black light around here somewhere so I'll find it and shine it around the engine bay in the dark to see if there's any dye.   I can't think of another way to track down the leak other than injecting some dye (if it doesn't have any) and having it charged up. We can't buy R134a off the shelf here anymore, so I'll run it up to Jiffy Lube and have them do it. I think I have a coupon. At the very least, the charge should last long enough for a year or two, according to history. I think this truck will be long gone by then. But cold AC is a selling point.    
    • Got the truck back today.  Called them yesterday to get an update, and miraculously my truck is finished?!?! The $13k out the door was complete bullshit!  Ended up being over $14k.  They added some bullshit service bulletin that I cant even find, where they replaced my radiator without telling me or asking me, and charging me for it.  Need to do more research into it, cause they leaked the first delivered radiator was ran over by FedEX.  Sounds like bullshit to me. 2.5 Months for an engine swap, which ended up being remanufactured, not new; ****ing ridiculous.  Brakes are squishy as hell, not sure if its from sitting.  Will give a couple days to see it that figures it self out.  GAVE IT BACK TO ME WITH 1 GALLON OF GAS!  Just filled the tank the day before drop off, more bullshit.  My dash cam SD card was formatted, not really much I can do about that. 3 year, 100k GM warranty at least.  Time to sell it and say **** off to GM.  Bad experience.  Cant wait for the survey email to come through.  Overpriced Raptor R, here I come!
    • If I forget the phone in the truck, and forget the truck in the phone, and reconnect.  It works great for the day.  Truck sits overnight, and the next day is a no go.  It will connect Android Auto via usb cable, but not bluetooth.   Ive tried Everything in this thread so far, and nothing works for more than a day.   I think I might have to go to the dealer and have them flash the pcm.   thanks for all the suggestions guys. 👍
    • 2022 2500HD Crew Z71 Duramax single alternator.  Recently had the primary (water pump / fan) belt tensioner pulley bearing to fail while hundreds of miles from home of course the plastic pulley melted and belt shredded which took out some wiring. Found a replacement tensioner assembly and belt to continue now would like to find a replacement for just the pulley and bearing to have a spare assembly in case of a repeat, the rest of the tensioner is fine. Has anybody here found a correct replacement part for just the pulley and bearing? Any help is appreciated.
    • +1 for the 3.0   Perfect for 1500 pickup towing duties.   Perfect engine for a 1500 pickup period. Huge torque at stunningly low RPM makes it feel a lot lighter than it is. The fuel mileage is insane for a tall and heavy 1500... 30+ on the highway. Mid 20's around town.   It's probably not perfect if you bought a 6.2 for the braaaaaaapppppp V8 noises and wrapping it out to 6k. The LZ0 acts and sounds like a small turbo diesel and there's nothing you can do to make a small turbo diesel sound like a big one, and you can't make an inline diesel sound like a V8 diesel/big Duramax. It's a different driving experience altogether.   Drive one, I think you'll like it, though...
