I'm new to Boxed Frame Trucks. Help me out if you will ..

I want to install Via Air Compressor & Tank outside the Frame Rail.
Drilling threw the Frame Rail would make the install quite a bit easier,
is this ok ?

 

I installed the airlift pump kit and it came with self drilling screws. I drilled a pilot hole and then screwed it right in. It wont budge.

 

Personally I wouldn't drill holes in the frame. I would use some existing holes and make a bracket that the compressor would mount onto.

I agree on this one!!

 

Agree, use some u nuts and slot them into the existing holes.

 

Thanks guys. I assumed it wasn't recommended, thats why I asked ..

 

i would avoid it

 

I drilled 4 very small holes (<1/4") in the frame rails for tank brackets when I did my F150 air. I will probably opt for something like mentioned here on this go around.

Don't want to nix plans for mounting compressor on frame rail and I know it works for many people. For me.... I end up around lots of water and simply don't want my compressor down there. I will be attempting to mount under the hood with the 6.2L which also provides shorter wiring for the compressor. ETA is next week so I'll do more nailing down on the location after it arrives. Seems like if there is room for 2 batteries up there that there should be hole a compressor can fit it. I wish it had an empty battery tray but I don't it's included without the 2nd battery. There is plenty of available space along the frame rail and it works great for many.

Some of the Jeep guys also mount in the cab. I've seen 'em mount the ARB dual compressor under the passenger seat.

Are you going to use an upfitter on the system??
Are you going to power compressors direct from the battery??
(I know that kit comes with pressure switch, relays, etc. etc.)
Just curious how you are planning to wire it up. Thanks for any info!!

 

Don't.

I just drilled through the frame. I figured 3 small holes (yes I only used 3 self tapping screws) wouldn't cause problems. I the hit them with some black urethane and called it a day.

 

From an engineering stand point, any holes in the boxed frame (or C channel) should be made as close to center of the vertical sides of the frame. You should never drill the horizontal (top or bottom) as the load is carried on those sections. Here's an example of allowable penetrations on a vehicle frame. Compare the holes you're attempting to drill to these.

 

Here's a link to guidance from Ford. See page 10 re drilling into the frame.
