Thread: HQ-WB Airbag Suspension

I have quite a number of people ask me here, private messages, emails and facebook about how to go about airbagging their HQ onwards.

Miz-10 prompted me to make up a little play by play on how i went about it. Something I never had when i was building my car. All i had was trial and error, mistakes and learning curbs.

Hopefully this helps a number of people.


1 - Sedan Diff, spring locators cut off to allow airbag bracket to sit flat and the locating ring that bolts up underneath to locate through the hole




2 - Slam Specialities 6" Bags with Pre-fabbed bracketry. the ones laying down are fronts.




3 - Tank and compressor positioning. the stubby 5 gallon tank fits a lot better than the long skinny one.



4 - RH rear bag mounted, and bump stop removed. I later cut the lip from where the bumpstop bolted to



5 - you can see the front spring cup cut out to clear the airbag. I'm running HZ chassis in my HQ with the support rails.



6 - bag in the hole. See the clearance. When you air out the bag expands sideways a little bit.. hence extra clearance.



7 - front lower control arm, the nuts that are there for the shock have been ground/cut off so the airbags bracket can bolt through



8,9,10 - gives you an idea of external shock mount positioning. This was utilizing all stock components and geometry. Drop stubs will give me the extra drop needed to get on
the floor haha.

11 - rear bag aired out. Can see diff tube to chassis clearance. That's the car sitting in the internal bump stops in the bags.



12 - painted, better idea of shock location etc.



13 - view of the lower front bag mount, the opening in the spring cup (I welded the skin after cutting for strength) and my relocated brake lines.



14 - idea of it all together. Not often you see a chassis assembled upside down haha



15 - sensors for the accuair auto level system. this is front right. Just took a lot of up/down to get the pivot point right.



16 - ecu on the left, fuses and relays in the middle, accuair 3/8" valve block.



17 - rear right sensor position. Took lots of ****ing about. Sensor is sitting on the brace that runs from the chassis to the trailing arm mount.



18 - shows full extension, sensor geometry and positioning of lower pivot point.



19 - low enough? Without drop spindles, sitting on inbuilt bumps in the rear bags. Will go lower once I mini tub, notch the rear a little and shorten the bag bracket. To compensate, ill just have to shorten the arm that runs to the level sensor.



20 - Under body clearance with the 15's on.

Wheel and tyre combo as follows -

15x8 and 15x7 Convo Pro's

4.5" BS on the rear, 3 3/8" on the front

245/60/15 mastercraft avenger tyres rear, 205/65/15 yokohama A drive front

Standard inner guards still in place, Rear arches have been rolled, pumped slightly and the inner well flattened with a mallet.
Standard length HQ salisbury with drum brakes.

Standard SHORTENED shocks fit front and rear. Relocation in front is designed to use standard style shocks, less the bar that runs through the lower bush from factory

Here's aired out Hancock




Glad to have helped at least a few people haha. This site is an abundance of info, good to be able to add to it

Good work Pont. Very descriptive.

Will definitely be considering air bags on whatever the next project is.

great write up!! definitely helps out heaps! ive just gotta work out how to go about doing the rear of my panelvan:/

Talk to glen at air ride in bayswater. He has a bolt in 4 link kit! Or use a 2 link setup with the long leaf for locating.

Pano tucking will look insane!

Yup! We bolted one of his setups in an fbody camaro, with shockwaves (coilovers except with an airbag) bolts into factory locations. Amazing stuff!

awesome stuff man, will have to take this info and use on the tonner...!

Whys that? seen many many done.. albeit on mini trucks and they've never had a problem? Engineer signs off on them.

However I do agree, just go 4 link
