Making a 1978 K5 GMC Jimmy 200% More Live-able With Sound Deadening

Yeah yeah, we know. Usually you’d expect us to spend hours removing sound deadening, and anything else that doesn’t help make a project lighter or faster. But look - sometimes, when it comes to a daily driver, it’s nice to be able to hear your phone/radio/etc. And a big block powered ‘70s Jimmy isn’t exactly the pinnacle of a quiet interior. So after wiring cleanup and whole lot of scrubbing, Zac and Dave drop in a whole bunch of Thermotec goodness.

If you’ve read this far, make sure to let Zac know he should give away his C10 in the comments.

This thing looks freakin sick. I love the patina. Can’t wait for the Baja suspension

[@anthonysmalawipredators8794]

BAAAAAAAJA UPDATE!

[@vincentmanzo5764]

BAAAAAAAAAAAAAAAAAAJAAHH UPDATE

[@klank1973]

Zach is my favorite Hoon. When he jumped shit car, that was AWESOME.

[@kentbeitel9966]

I’m loving the new professional unprofessional content! 👌👍

[@Clappedoutgarbage]

Thank you Zac for keeping classics alive!

[@kevincrosby7123]

I oddly like how informative and narrative Zac has been with his last several videos.

[@MountainSlayers]

Taking notes for the 78 Bronco trail rig were slowly building!

[@shoottheheadcase]

I'm really enjoying how Zacks build series has been edited and presented. It gives it an air of competence, unusual for Hoonigan!

[@cpmxxx86]

I would love to see another (I know.) channel that airs uncensored versions of everything. You guys do a good job to make the bleeps flow but I think it would be cool hearing Zach drop the f Bombs.

[@jonmether8276]

this truck needs a big CB antenna sticking out of the roof lol

[@CharlieBennici]

Or two giant ones off the back bumper. Sorta like whips

[@xxmurdernova12]

100%

[@gravityze]

Please keep the door cards in there lol love em

[@chrisleon774]

Glad one of my favorite KZbinrs is doing a K5 build. Mine’s finally getting the attention she deserves and am definitely taking pointers from you. I might just buy that same cluster!

[@Thebakedbaker413]

I wrote three different fume/fan/inhalation jokes trying to make a decent comment but each one came off as airy... love you guys!!!

[@unclebob540i3]

Love those old K5s! Dakota dash looks sharp. Dropping an LS in was the best thing I could have done to mine.

[@jshaw125]

*WE* are gonna keep working on that. Good job, Dave.

[@InsiderMisfit]

Yes man! Keeping it og, I love it. Wheels look perfect. Awesome direction with the build.

[@kdtest]

Perfect timing for me starting work on an '80 Jimmy!

[@jbustin94]

I have a 77 C10 & 84 K5 myself. Shouts out to Zac for all this helpful content & product info.

[@buildingsalvage]

This is exactly what I want to do to my old F150, damn. Touch of modern with the classic looks.

[@MegaPastorn]

Best looking model of the 70's 4x4's!!!!! Keep the good work up.

[@Dadmoves49]

Had an 84 k5 for years man i miss that beast. Love those trucks.

[@motomax13]

You’ll always be my favorite hoonster

[@gaydes1012]

just got done working on my 78 GMC jimmy and no I can watch Zac work on his!

[@amarkuljanin4540]

I love Zac"s tatoo on right arm "DONT DIE" Probably I will get one too

[@Cloudy5.0]

I know you’re keeping it stock, but nothing will beat the sound of the boom tubes and that Texas Speed in Boomhauer. Just something special about an old squarebody screaming in a cloud of smoke.

[@paulEG6]

That cup holder is DOPE! the rest of the truck is cool too obviously lol

[@MrBillsfishin]

Damn those Dakota gauges look amazing. Cant wait to get some for my K20.

[@martinholland2796]

U gotta love zac 🤣🤣🤣

[@AlistairLattimore]

I love Zac’s content, it’s god damn great ! 😁

[@H00sierD4ddy]

I dig the foot dabs! Keep it safe!

[@bionik6861]

I had a 1990 blazer. Sound deadining is the most crucial part to building one of these.

[@rudypv2976]

Cool project it inspires my GMC k5

[@brianz28lpe]

Looks and sounds amazing! Love the gauges!

[@williamsanders468]

Those wheels look SWEET!

[@the_nondrive_side]

Well done. Back to Back winners.

[@Fallyn2911]

I love the clip of Blake!

[@dvorcemkrmotorsports8835]

Looks good mate. Keep a the good work Cobba,

[@emotionalcontentmediaunltd2267]

Thanks Zac! I wont die!!! and.... I love this truck!

[@joealex65]

Can we change the name of the channel to **Hoonigan Gaaaaaaawd Daaaaaaaamn Cars**? 😂😂😂

[@benthego-fastkid72]

Zac should put some thermotec heat/sound shield on the insides of the doors. Those create a ton of noise when undeadened.

[@autobez3132]

Is comings together really good

[@charlespalmer793]

Thank you for the videos, keep up the good work!!!!

[@RumbleKar]

Last time I was this early, I ended up with a kid.

[@5485bimmer1]

Beautiful k5 😍

[@ScrizzDubb]

Zac's been extra rad ever since he started building trucks

[@itsameyaboi]

I like the opening, though it might be a smoother transition if you cut the text slide when Zac says "On the last episode of this build," just thinking, the shreditors have been killin' it lately!

[@RyanMcIntyre]

Looks 100 times better!

[@christophersanders5007]

I wish there was an aftermarket wire harness, and dash gauge set up for my square body. I have a 1991 1-ton square body with 4L80E transmission, and since 1991 was the one and only year a square body came with a 4L80E trans it is a one year only wire harness design for both the engine compartment and interior dash.

[@jakemcf]

Literally just finished on my 2004 Jeep GC. Now I don’t have to yell at my passengers!!!

[@MRTuning704]

I just picked me up a 1979 Oldsmobile delta 88 6.6 and it’s a boat ⛵️

[@joshuahalford4071]

@Zack you should put mud tires on the new wheels you got for it that would look bad ass 👌🏽💯

[@BrandonApplefield]

I want the C10, definitely give it away! I read the description.

[@GiletheCarGuy]

I picked up an $800 '79 K5 over the weekend.

[@ethanlee7624]

We need some more k5 content

[@antoniorocha1643]

Crank these videos out man we are anxious 😂

[@raga4347]

Ffs Zack where the smoke come on bro that's what I've been waiting for

[@anthonysmalawipredators8794]

K5 owner's are real deal truck guys.

[@mrnobody9153]

3:30. Nice tat, very motivatioal.

[@WcSuka]

I wish I had the money in this build to throw at my 91 square body burb I'm working on

[@Ran-dom1]

before you laid down that heat or sound barrier stuff you should've primed the stuff which had surface rust. I know cali vehicles don't rust much, but it'll further increase the longevity of the truck.

[@1Also]

Senor Mister Zachary, Why shouldn’t I buy a 77 GMC C15 Sierra farm truck straight 6, 3 on tree, 40,000 of KMs? Thanks

[@bradruiz9461]

Man that looks sweet... what size tires do you have

[@dzinek1134]

Good job 👏 👍

[@rcdudes123]

How does this thing pass smog? Badass build

[@mattpish9675]

Yo mister Zachary #LMC Truck has that grille and so much more!!

[@carlosd972]

GAWD!! i love how it looks,keep the suspension as is please !!!! (maybe the paint needs a buff) please dont put a stupid high lift :C it just ruins it

[@bigrich7026]

You have to go to currie to keep it somewhat driveable?

[@nananarex254]

Life hack brought to you by NaNaNa: Use a mixture of rubbing alcohol and dry ice, smash it into a paste consistency and apply it to the factory sound deadening material. It causes the factory material to crack and pop up losing it's bond to the floor panels. Saves a ton of work and headache when removing factory sound deadening.

[@EYSSEN2001]

The background music rock's

[@SchnelleKat]

7:57 Now that's bitchin... can't go wrong w/ stock look! I'm bout to pick up an 84 GMC Jimmy, $1000 LS swapped, gonna drop in a Built SBC. Old Skool Baby. even better Waggy Wheels. ;)

[@CraftwerksMC]

Zack, as many others will probably point out its good you didn't waste any more time getting the dash out because its actually spot welded in.

[@ajvillard8266]

GMC and Chevy are pretty similar so the grill still fits tbe Jimmy

[@MindsNmotors]

No heat barrier on the roof? In Cali?

[@SquarebodyKid]

I have a 75 gmc grille, its pretty nice but could prolley use a coat of paint if you're still in need.

[@justar6865]

Yess

[@iananderson4897]

Is that a Caddy on the lift in the background?

[@DMD81773]

I know im a bit late but that dash is spotwelded to the widshield frame.

[@hodad200]

Give the people more Nads!

[@ThatsQuacktastic]

Zac, wheres ur Hoonigan/HeatWave Laser Face joints at???

[@marshal7376]

2min in actually starts video. 7min episode, surprised it wasn't a little clip on the bonus channel.

[@Kicks001]

I bought a '78 K5. It has a radio antenna located on the hood near the passenger door. No other Blazer I'm seeing on KZbin has an antenna. Why is that?

[@jamespatrick5447]

I have some OG phantom gauges for this

[@caleallinger5502]

Nut!

[@anthonyimler]

Why not switch grills with the c10 then?

[@bigben3898]

What size tires are those??

[@chrisleon774]

Can we get a parts list for the interior?

[@austinrohlfing1683]

Sweet

[@gustavofigueiredo1798]

I'm having a feel that this thing is doing Baja or Mint, or something like that in a near future...

[@ethansimkins2176]

nice

[@KapteinFruit]

That big girl right there is an American I can get down with. ;) I bet she smells like freedom.

[@Super_friendly73]

Could anyone please share a rounded number on how much money will it cost to buy these parts and ship them

[@ericksanchez7787]

I dont want to be the new pagani gaming but I'm curious on what happend to shitreg

[@jeremiahcorpuz1078]

Even in quarantine Scotto still hasn't worked on his car😂

[@whitieford_rc948]

why don't you swap the grills between the 2 trucks

[@Ceo8203]

What kind of cluster is that

[@claytonprescott6154]

Hopefully there were no cracks around the seat floorboards they were prone to that

[@grasshopper1g]

put the one from the C10 on their. Then the one you just got on the on the C10, after you clean it up.

[@backseatdriver4833]

New account! Under construction!

[@awwsheeet]

word edgar in the house?

[@KG-qw4fv]

Why did you not get new carpet

[@robertbelote5273]

Slide times at honnigan high.
