Got my Load Lifter 5000 airbags on today.

 

Look at the poor factory springs lol.

 

 

The extra spacers are bolted to the spring pack and not just stacked on top of the factory block. The springs were bowed before I added the spacers. I also have no idea what happened to the factory overload spring.

My 02 looks just like the above photo. I think the overload spring only comes with the camper package. My 96 did not have one anyway.

I can’t believe I didn’t notice the top plates are missing. One of these days I’ll have this truck squared away.

Basically in a nutshell, if you had all your OEM hardware you most likely wouldn't need airbags.

After seeing what all is missing your probably right. These air bags do ride VERY smoothly though.

 

 

I’m going to throw an idea out that might sound stupid (not unusual for me) and let me know what y’all think.

 

I don’t tow/haul heavy loads with my truck  that often. So, I was thinking about putting new 1/2 ton springs on my truck and using the airbags when I tow/haul heavy things. Any real reason why this wouldn’t work?

I think it's better when you go to sell this truck if it does not look messed with or have missing hardware. I would pass on a truck if looked like that underneath. In my opinion it looks very bad. Remember this coming from a guy that is very opinionated and fussy about having things right.

I’m never selling this truck so that’s not a concern. I bought it to keep for the long haul, othwise I wouldn’t have sunk so much time and money into it lol.

 

It currently doesn’t have a dash and is painted with black bed liner. No one besides me would want this truck anyway lol.

My spelling suck my grammer suck

Mostly likely won't work. 1/2 ton springs will most likely be too soft and have a constant squat. I would do a 3/4 ton spring without overloads.

 

I'll grab picture of 1/2 ton springs.

The new 3500ks with OEM air assist suspension are similar to that. They have 2 softer leaves with airbags vs 4 stiffer leaves. The biggest differences is that they have 2 half leaves under the main leaves that help control axle wrap, and provide some overload help. The Cummins torque could do some descent twisting to the 1/2 ton springs so you would need some sort of anti-wrap device. That could be 1/2 leaves or traction bars. 

 

With 5-10 psi in the bags the 1/2 springs should ride nice and not squat. 

 

I just looked up the curb weights for an 05 QC LB 1500 vs 2500. 2260 vs 2690... 230lbs different, not a lot. 

 

Here are the best pics I could find of the 3500 air assist suspension. The lower, thicker, leaves are the 1/ 2 leaves.

Thanks for the info! I’m going to either buy or build a pair of traction bars later on. 

 

The end goal for this truck (suspension wise) is to replace my current 2” coil spacers with a pair of 3” lift progressive rate springs and install some extended control arms to properly center the axle. For the rear I’m planning to use the air bags as an add-leaf.

You will need a longer track bar to center wheels side to side and longer end links. You may already have longer shocks.

@AH64ID 3rd Gen suspension is way different than 2nd Gen. Kind of an apple to orange problem.

 

Here is stock 2nd gen 1500. Yes it would squat... Spring leaves are a bit thinner.

 

Same 3 thick but 2500 appear just a bit thicker. The bottom leaf on the 1/2 ton is for sure thinner.

I have a DOR track bar that’s good for up to 3” of lift. I also have a pair of the 0-2.5” lift Bilstein 5100’s and extended end links.

So this 3/4 ton leaf pack has 3 main leaves, an overload on the bottom and an overload on top. My leaf pack also has three main leaves but there is a gap in the spring alignment clamp like it’s missing one. 

 

 

In the end I’ll probably just buy new 3/4 ton packs and be done with it. I’m done with all of the “WTF” mods that have been done to this truck. 

My point was the standard weight on the rear axle of a 1/2 vs 3/4 isn’t that much different. 1/2 springs will support empty weight without issue when combined with airbags. 2nd gen 1500 springs are rated for 3900lbs. At 10 psi airbags support 500 lbs of weight which more than covers the difference. 

 

Its not apples to oranges, it’s lbs to lbs. 

 

axle wrap will be the biggest issue, which is why I showed how it’s controlled on an OEM setup.

I’m also going to be using the lock-n-lift airbag spacers instead of a regular add-a-leaf for the extra lift.

I managed to scrounge up a couple of top plates so there’s that lol.

I'm glad your springing into action on getting it right. I feel a whole lot better about it now

Lol.

 

It actually drives me nuts when I know something isn’t right on my truck. 

Any update on your project?

Current setup is working great. I still need to install the top plates but I’ve been busy getting things ready for the new RV. Looks like I’m going to be installing a 5th wheel since our original RV choice has changed.
