Best airlift-bumper install video available!!

[@kurtlesser2684]

Dude, that inner brace to the pintle hook that you left off is where your pioneer rack latches on to hold it in place.

[@nitrofish1974]

It really compliments the hum. nice work 👏

[@chuck1607]

That was a very informative video. Well done sir.

[@farmsgrace341]

Damn, dude. You need to get you some friends. HMMWV parts are heavy. Helping hands are necessary some times. You handled the bumper very well, though. Congrats.

[@veuvava1529]

Thanks for the video. It is a good help indeed. Much appreciated.

[@Osakaenterprisellc]

Sure helped a lot . Thank you.

[@cruiez2008]

Very calm presentation.

[@nirpeer1202]

Great video Thank you!

[@JUAN-xr4hs]

PLEASE LET ME KNOW WHERE YOU BOUGHT THE BUMPER, I see its all boxed in (close no gaps) super nice video.

[@billyraematthiasonian4598]

Great work. Thank you

[@jimbella9353]

PLEASE ...consider using "IMPACT' sockets whenever using an Impact wrench; The Air-lift/tow hooks are to mounted using a castle nut.and wave-washer so enough tension can be applied to prevent the "hook" from flopping (rattle) around. The original "Pioneer Kit" will work with an Air-lift Rear Crossmember, but additional bracketry is required. Forgot to transfer the 2 Pintle Hook diagonal braces to the Air-lift Rear Crossmember.

[@Osakaenterprisellc]

Jason is the list of parts updated with the bolts that you had to change out?

[@Capone2525]

Loveing it need that for mine how much was that bumper?

[@chuck1607]

Why didn't you use the inside angle brackets? ( You removed them when you unbolted the pintle hitch)

[@jasonhuofficial]

Chuck, I believe I ended up ditching that because the added thickness of the bumper made it so that the pintle hitch bolt became so short at the end that the hole for the cotter pin was no longer showing. I wanted to be able to stick the pin in there in case the nut backs out.

[@okjd159]

I would recommend that you stop using chrome sockets on your impact as they will fail spectacularly and they are not designed for that kind of abuse. I have see someone almost loose an eye. They are thinner than impact sockets and if impact sockets fail they will only expand with the crack that will form as they are of a softer material. Other wise a great vid.

[@jasonhuofficial]

I appreciate your comment Eric, and you are absolutely correct. Thank you!

[@okjd159]

@@jasonhuofficial The question is are you going to get impact sockets? I got a slant back Humvee and waiting for the EUC reply to pick mine up.

[@jasonhuofficial]

@@okjd159 I actually have some. For some reason I didn't use them for the video. GL on the EUC, I hear it's been taking longer and longer to process.

[@okjd159]

@@jasonhuofficial Then sop teaching bad habits LOL.

[@hummerguy]

@@okjd159 Same for mines, I'm waiting on a EUC, did you get your slant back yet? If so, how do you like the top? I want to convert mines to a slant back

[@chuck1607]

Do you have the P/N for the oval shapped rubber body bushing?

[@jasonhuofficial]

Sorry, I do not.

[@НИКОЛАЕВСКИЕГОЛУБИДИМЫЧСЕВЕР]

Сколько стоит этот Хаммер?

[@ShiftLounge]

Tactical Asians are the best asians! Haha

[@AlexanderJScheu]

why you are mounting an Airlift bumper ? Do you think on Invaders of China Soldiers; and *IF - who is lifting ?? and where you will move ??

[@HK-qj4im]

Airlift bumpers provide some rear impact resistance. + they look cool. For mud flaps you need the bumper. And the spare tire carrier. He needs the bumper because he is an AMERICAN. That is enough.

[@PracticalTacticalFedeli]

@@HK-qj4im well said
