Rear airbags
This may be a stupid question, but I know nothing about air ride installation. I am currenty working on my 78 Blazer 2wd but have the same question on my 80 & 81 c10 2wds. Do i have to install a 3 or 4 link on the rear, or can I install brackets kind of like overload airbags and still lay down low?? Any help would be greatly appreciated. Anyone know of a complete kit at an affordable price?
Thanks

Re: Rear airbags
You will not lay frame or drag bumper on a AOL setup. You are still bound by the original equipment. Search AOL and you will see what a aired out system will look like.

Re: Rear airbags
Things are kinda slow over here in this forum. I'm gonna post this question over in the main forum. I'm not trying to take over but there's somebody in here that has to know the answer.

Re: Rear airbags
There are plenty of guys who've done this and know the answers but aren't so active posting as when they were knee deep in the project. If you did a quick search of "bags" in this forum you'd find plenty of projects and ideas until someone sees your question. I'd search for you, but I'm at work.

Re: Rear airbags
Dosn,t seem to be to much demand for blazer stuff for 4 links etc. for someone to make a bolt in kit so I,ve found but with a little fabbing can be done.I,m just finishing up a AOL setup on my 78 with a c notch and 3 leafs and the pumkin hits the floor boards,looks really good,low enough for me but know I have to notch the 3 crossmembers for the floor for the driveshaft.

Re: Rear airbags
Quote:
More lift because you are putting the bag further up the lever so you are getting more than a 1:1 lift ratio. Airbags typically are rated for anywhere for 2500-2600lbs per bag. So two bags on the rear of a truck should be able to support 5000-5200lbs. As you increase the air in the bag the stiffer the bag is to handle the increase load rating. So a fully inflated bag while stiff as a brick should be able to support the 5000lbs. If you don't have 5000lbs to weigh it down your going to ride like a bucking bronco. So for a good ride you have about 2-4" of adjustability before the trucks starts to ride rough. Now if you move it closer to the fulcrum point (closer to the front of the link bar) the bag will "see" more weight so it will allow you to inflate the bag with more air and still have the "cushiony" ride that everyone wants. As an example my Ranger had a bag on the lower bar and would get 15" on lift from a 6" bag. However because I had so small of a bag and it was leveraged so much if I had a few people sitting on the tailgate I could get no more than a inch or two of lift fully inflated. So depending on what you are going to use your truck for should dictate where your bag placement will be. If you plan on towing I would do air over axle. If you want to just cruise with it I would go further up on the lower bar. I hope this explains it a little bit.. If not please just ask.. |

Re: Rear airbags
I don't plan on using the blazer for much more than cruising. If I ever installed a hidden hitch I might pull my utility trailer with 2 quads. I just liked the ease of the AOL since I don't weld
