Question About Air Helper Springs


Recommended Posts

Posted

I would like to add to the load carrying capacity on my 2004 Sierra 1500, and also lift the rear just a little. I have a pair of 1.5" add-a-leafs in the rear, and was thinking of adding Firestone air helper springs so that I could take some of the load off the leaf springs when I'm hauling firewood or other heavy loads. Would these air helpers also give me some extra height when empty (1/2"-3/4") if I wanted it ? The truck has Bilstien shocks that are rated for 0-3" lift, so I think that they would still be ok.

Thanks.

The air bag kit should have a regulator to adjust pressure (to change height) on it. You should be able to adjust the ride height of the truck using that.

I can raise the back of my truck up around 3" if I put around 70 pounds in, but you wont enjoy the ride much. I put around 20 or 30 pounds in with my boat or snowmobile trailers and helps alot since the suspension is so soft on the newer trucks. If you leave too much air in them unloaded on my truck it will just about catapult you through the windshield on a country road.

Thanks for the help on this question. I plan to get air helpers, but I'm not sure what brand is best to go with: Firestone, Airlift or Hellwig. Anyone have experience with these?

Thanks

post-45992-1225552782_thumb.jpgI went with the firestone bags just because thats what my buddy that sells bags said to get. I got the 5000 pound ones but I have heard the 3500 pound ones ride a little better unloaded. I dont have a picture of the bags on but I have where I mounted the air valve. I tied both together rather than individual because I only use them for the pulling trailer and it is pretty level.

    • 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."    
    • 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.  
    • 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.
