Truck mounted air compressor

Its a 2019 F450 Crew Cab. I believe it already has an exhaust break.

I have already purchased the Air Lift LoadLifter 5000 Ultimate+ air bags. Just need to decide on a system for airing it and providing a supply for tires. Hopefully a quiet one.

What kind of truck? If you're installing an exhaust brake, you might be able to kill two birds with one stone.

Get the kit with the air tank. It comes with a coil air hose for filling things outside of the truck. I didn't do that but had times I could have used the reserve air in the tank.

I don't see the need for 2 systems. If you want one big enough to fill tires it will easily handle inflating your airbags. I would just get the gauge kit for the bags and let the air supply be your big tank.

Yah, I was going with the Hellwig Air bags and I 'Think' they have a compressor too.
I had one, Firestone Bags and compressor and it worked well. Noisy as heck to got a Manual switch to shut if off for those early morning departures, to spare the neighbors the noise..

I 'Believe?' it's a kit as they need the compressor part for the Airbags, just need a holding tank for the tires etc which I think is needed. I have keep some 90 lbs in mine and most gas stations don't go that high... so it's a necessity for the most part..
Hope that helps...

Depending on truck, it might be a close install... not enough room or something like that..
