The LFD Off Road Thread

We've got four completely redesigned ones going through welding this week, and then next week one of our employees is heading out to Moab with it installed for vacation. We'll see how it does on his trip.

If you need help testing, i would be happy to be a guinea pig!!!
 
Based on this, it appears a 450 might be too large for this compressor plate. Also, where did you find that rubber cover for the male air hose connection?

that cover came with my 300 as it was originally a portable version with the handle. I removed the handle when I modified it.
 
Does the 3/4 require drilling and or silicone to install?
Interested while I still have my stimulus money haha

So my 450p appears to have not come with that little rubber cover for the male end BUT I found that a normal schrader valve cap fits snugly over the end. I'm pretty sure a rubber 5/16" vacuum cap would fit over it perfectly as well. I was able to fit a 1/4" one by expanding it a bit and I fit a 3/8" one by pushing it further over the collar on the male connector.
 
Also, I purchased the LFD air compressor mount and plan to try to fit the 450 on it. Based on the dimensions of the plate and the 450 mount points I think it will fit...barely. I plan to drill new holes if needed (probably). I will let everyone here know how it goes!
 
I have a question about the rear bumper. What are the 2 little cut outs for that are near the shackle mounts, are they for lights? If so what size?
 
Curved Fairing Vibration

Some vehicles we've seen a need for double sided 3M tape under the front feet on the rack. We've also seen a few bad welds crack on fairings every once in a while.

If you send us a Pm we can try to work through and help troubleshoot.

I just completed a 2000 mile round trip between CA and CO on 80 mph highways and was limited to 75 or less, depending on the wind speed, because of the same vibration issue with the curved fairing. I have a feeling that it's the gap between the bottom of the fairing and the roof that's creating an airflow/harmonics issue. The vibration actually went away when i opened my sunroof--either fully opened or tilted up the back--so changing the airflow would fix the problem.

It was really frustrating that I had to slow down far enough for semi trucks to pass me in order to not have the rack vibrate itself off of the roof. In the first 100 miles I hit 85 mph on a down hill and it sounded like it was vibrating metal on metal against the roof, but fortunately there was no damage so that wasn't the case.

I'll PM you on FB. I definitely need to find a solution!
 
Has anyone else had problems with the new curved front wind faring (XLFOR017-7) vibrating on their full length racks? Got mine on and every time I get above ~70 MPH, my wind faring vibrates CRAZY hard. It is so bad I thought I put a wheel out of alignment or a tire out of balance. Shakes the whole 4R

Yes! I just finished a 2000 mile trip where I couldn't go the speed limit on 75-80 mph freeways because of this issue. I didn't have the front feet on, so I'm sure that exacerbated the vibration, but it's an aerodynamics issue, not a structural issue. I think that closing the gap between the fairing and the roof may solve the problem. When I opened my sunroof and disrupted the airflow the vibrtation would all but disappear.

I saw that [MENTION=290929]YellowSnow[/MENTION] added a Prinsu style fairing to close the gap, which solved his wind noise problem, but he didn't mention the vibration issue.
 
My guess is LFD had a bad batch of powder coat and/or had to change who they were using. That’s why they were quick to send me the aluminum replacements no charge, and also why they now state “rust free” on all their racks...seems redundant to have to specify rust free, unless there was issues previously.

On another note, I switched over to their curved wind fairing and noticed awful wind noise even at low speeds, so i added the Prinsu style rubber door seal off Amazon and it was minimized drastically. It also seals the fairing against the roof and all but erases the gap.

Could you send a link to the Prinsu style seal that you ordered? I have a horrible vibration issue that starts between 75-80 mph with my curved fairing and I'd like to see if closing the gap will fix it. Did you have a vibration issue at high speeds, too, or just noise?
 
What's weird about these is that we've run these for more than a year with many, many different vehicles in our fleet and not had that issue. One of our employees just did a 4,500 mile trip last week with his out to Moab and back, and we did a similar trip last year to CO too.

We are experimenting with a few different edge trims with seals right now, should have some available to send out this week if anyone wants to try one.
 
I'm curious about the rake angle of the vehicles with vibrations vs without

if you are having vibrations, what kind of front and rear lift are you running, what's your rake angle?
 
Mega thanks to LFD for sending me a replacement Integrated Wind Fairing Crossbar, free of charge. It's awesome to see a company that listens to customers!

LFD Off Road - Integrated Wind Fairing Crossbar

No vibrations / jack hammering out of this one.
