Hello all,

I was reading the recent thread regarding adding a leaf spring to a 2500hd to essentially make it a 3500 srw. I'm thinking of doing it myself because i want the extra load capacity and the extra height would be nice as well.

I'm just wondering if anyone could tell me what the pros and cons of air bags vs. an extral leaf srping would be. I would like to get a few inches lift out of it but i don't want to do a lift kit, i'm interested more in the extra weight capacity. Thanks.

Well I don't have hard facts for you just my personal experience. I drove an 02 Crew Dmax with all stock suspension except some airbags and it was the smoothest ride that I had had from a truck. My half tons didn't ride that nice. I am looking into getting the airbags once I can afford them for the better ride quality and for leveling out loads. Hope this helps ya out.

I use Airlift air bags to maintain normal ride height when carrying my 3500# truck camper. They work very well.

You're better off with an additional spring, air bags can leak like Bill mentioned.

As far as ride quality, after adding a leaf to my truck, the ride quality was improved and felt more stable too. I had a 1/2" heavy duty spring added which would be the equalivant to two of GM's springs. When I had a palet of salt in my truck, my truck still sat higher then it did stock with all that weight. The palet was over a ton in weight. I gained 3" as well.

And this is what it looks like after I unloaded the palet..

Hen Avenger: Where did you get the additional spring? I don't know much about suspensions, so did you just add the additional spring to the existing ones, or did you have to replace the whole spring configuration?

 

Also, what size BF Goodrich tires are you running? I love the look on the stock rims and wanted to add similar to mine.

 

Thanks

I had the spring added at a spring and suspension shop. They took off existing springs, and cut a heavy duty spring to size, and added it to my existing set. Cost $400 cash only! I'm running 265's on the stock rims, I've seen 285's on same rims on a GMC, but thats maxing it out for the stock rims. I like the 265's much better then stock, for one they won't peel out as easy on hard exceleration and are a heavier tire then the stocks. It will affect mileage some, seeing it is a heavier tire. Those wheels are the premium wheels for that generation of truck, I like them alot.

 

Like I mentioned, the additional spring worked wonders for me, the truck handles alot better on bumpy roads, and can accomodate an extra 2000lbs. With the additional spring added, my truck sits slightly higher then a F350 and 3500. My next project is to get heavy duty torsion bars installed, so it will eliminate plow bottoming out while driving over uneven roads. I think I pretty much have mine cranked all the way up, but am not 100% sure.

Thanks guys for the input, i'm still pondering but I think i'm leaning towards the extra leaf spring because it's simple and there's less things that could go wrong, plus the extra height would be nice.

 

Thanks for the link Norsemanberg, and thanks for the pics Hen Avenger, they're a great help.

I personally would seek out a spring and suspension shop near you. They will have the HD springs they can customize to your existing spring set up and they are strong. Stay away from the gimmicks online, and make sure the spring is 1/2" in thickness, this way your suspension will be better then a 3500's. I didn't have a micro, so i used a tape measure and when I measured the OEM springs they were 1/4". You really notice the difference right away and handleing over bumpy roads will basically eliminate back end kick feeling. And if you tow (depending on how much weight you pull) you will notice the truck will not drop as much or in some cases drop at all (depending on how much you are pulling). Only con is having to reach in bed is harder because I gained 3", but that is something I can adjust too.

I haven't put them on the 2500hd yet, but I ran Supersprings on my Dakota for many years. They are fantastic both loaded and empty. You can put them on yourself in no time too!

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."

      2020 Trailboss 6.2 replacement

      By 2017Z · Posted

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.
