Ford L9000 Episode 18: COMPLETE FRONT AIR RIDE DIY, no kit needed!!!
HTML-код
- Опубликовано: 14 окт 2024
- In this Episode on my 1987 Ford LN9000 I fabricate and install a complete custom front air ride system on the truck to improve the ride quality and allow height control via fill/dump switches in the cab.
For reference these are rear bags from a Kenworth Airglide setup. 3.9" minimum height, 7" design height and around 10.8 max so they go low enough to fit a front setup. 5100# rated at 80 psi so good weight carrying capacity for this size truck. The Kenworth part # is K30322. Just beware that the air fitting doubles as the mounting bolt and it's big (1-5/16" - 12), requires a Kenworth specific adapter fitting so it adds to the cost.
I loooove those bits.
Looking forward to the shock install and test drive see next week
Thanks, it might be a hair longer wait though, I’ve got another L9000 project happening in the next week or 2, stay tuned!
@@robstruckshop80 sweet
not bad
project coming along nicely
Thank you sir!
Looking and Working Great!! Been looking forward to this video. This video has help me a lot in trying to configure “none work” truck air ride. Been Very Motivating! Keep up the Videos!!
I appreciate that, glad it could help!
Beautiful
Great job!
Thanks!
Did you have to isolate one side from the other via a check valve or dual outlet ports on the solenoids? Always wondered if sway control was needed in cornering without something keeping each bag isolated from the other.
I’ve heard that from a lot of people as well. Most suggest check valves or just going to a dual leveling valve setup and ditching the solenoid. I’ve had zero issues and don’t have any lean in corners. Virtually every rear axle air ride setup is built that way too, so it stands to reason that it wouldn’t be a problem. I may change to a leveling valve set up at some point so I’m not relying on a solenoid, but I won’t waste the money on 2.
@@robstruckshop80 Thanks for the reply
I took one look at that and that was enough. Good luck 😅
I drove one in the 90s. Manure spreader. Tough as hell. 360 Cummins.? It would fly with a seven speed transmission. There is never enough time and goodies to put into your own Rig. I'm a loud woman so I always liked Detroit Diesel.
7 speed Eaton Fuller. Easy shift and no splitter
I didn't catch it if you mentioned it. But I was wondering if you have any info on the type of bag you are using. Great setup I like it.
They are rear bags from a Kenworth Airglide setup. 3.9" minimum height, 7" design height and around 10.8 max so they go low enough to fit a front setup. 5100# rated at 80 psi so good weight carrying capacity for this size truck.

@@robstruckshop80 Thanks man. I really appreciate the detailed info. I think these are exactly what him looking for.

What air bag did you use in your
LN 9000 if you have a part number that would be awesome!!!
On the front air setup it’s a Kenworth K30322 which crosses to a bunch of aftermarket numbers. Note you’ll need the Kenworth specific fitting to feed and mount the bag too .
what control valves did you use?.. and i am assuming the back axle doesn't have mechanical load leveling switches
I used Vixen 3/8” normally closed valves, Amazon specials. I originally plumbed the rear end with the same valves, but didn’t like having to constantly adjust pressure in the cab to compensate for load so I eventually converted to a standard height control valve/dump valve setup
can i see the new setup
so the 2 valves on the firewall are solely for the front bags?? ine to raise oneto lower?
Correct, they are normally closed so the system holds air- 12v power on one side of the switch opens the fill valve, 12v power on the other side of the switch opens the dump valve
did the bags come with the top mounting bracket?
The bag Kenworth P/N is K30322- that’ll cross to a ton of aftermarket numbers. It comes with the mounting bracket but you’ll need this fitting a1truckparts.net/products/air-bag-adapter-kenworth-177-3015-automann?variant=40080624386113¤cy=USD&gclid=Cj0KCQiA_P6dBhD1ARIsAAGI7HDU5e6xAFewP3JfMNbWb9EUxKbhFiWOCYYxd7jrVeHeySOf34XsfO0aAr4IEALw_wcB to adapt to the big 1-5/16” mounting stud- the fitting doubles as the nut.
@@robstruckshop80 sadly that particular bag will not work for me... i need something that has a lower collapsed height.. i have found a bag that has a 2.20 inch collapsed height but will probably have to mke my top bracket
Am the first comment so can we have a convo where I call and talk to you
What’s valves did you use?
They’re just Vixen valves from Amazon:

@@robstruckshop80 I appreciate it brother. I’m building a front air ride kit for my cabover
I’ll keep an eye out for that, love that freightliner
@truckerstyleshawn any progress on the cabover?
It not for commercial operation its for pleaseure NOT FOR HIRE use
??
@@robstruckshop80 the truck you are working on is not commercial
I have used it commercially, it was inspected, plated and insured commercially for a couple years
@@robstruckshop80 I understand it may have been a commercial used truck previously but not you are turning it into a NOT FOR HIRE truck project and it will be used as a Private use truck for shows and parades etc etc etc
Look my ford truck l9000
