Building of a Dynatrac ProRock 80 Full-Float Rear Axle

Jeep parts purchased through this Amazon link will help support this channel and at no cost to you: www.amazon.com...
With more and more people building up their Jeeps JK Wranglers with 40" tires and pushing them with the kind of big horsepower that a HEMI or an LS swap will provide, there's been a real demand for an axle that can handle the abuse and Dynatrac has the answer for it -- the ProRock 80! With an 11.25" ring gear, a 2" diameter pinion, 40 spline 4340 full float shafts and all packaged in a high clearance, light weight rigid housing, there really is nothing out there that comes close to all that you'll get with this axle. In this video, you'll get to see exactly how it's made and right here in America!

Seriously the production quality of your videos gets better with each new video! Keep up the great work!

[@wayalife]

Thank you.

the precision and man hours involved in assembling is staggering. Great to see a "How its made" for jeep upgrades. Great video.

[@wayalife]

Glad you enjoyed it!

[@onebridge7231]

Love all the old school machinist talent and manual assembly skill set!

[@Stuka87]

Whole lot of labor that goes into one of those. Always nice to see products that are 100% made and assembled in the USA.

[@JonathanLahr]

I've always appreciated the work of a machinist since both of my parents were in similar businesses...it seems like an art that is perfected over time and they absolutely make it look much easier than it really is to create out of hunks of metal, something that will work, work right and be durable and impressionable...give those folks a raise! : )

[@josephnovak3485]

Great to see a wayalife vid showcasing american craftsmanship and attention to detail!

[@84gssteve]

This is why I taught myself to setup my own axles. There is no way around the labor involved with setup......rather learn to do it myself than pay someone to spend hours setting shims, bearings and lash. Much pride from 10 years of crawling on 44's I did on my own.

[@eighthnotch_]

How'd you learn? I've been slowly acquiring tools as I work on my Cherokee. I'm getting to the point now where re-gearing etc. would be a very handy thing to learn.

[@nickjovanovic5258]

probably the best setup to run on any 4x4... overbuilt with maximum clearance i like it very much

[@SegoMan]

I can remember back in the early 80's asking both Dynatrac and Currie about putting a full floater 60 in the back of a 79 bronco, they both asked why would you want to do that? So I did it myself, I did a hybrid 44F (Tracloc) front 8 bolt conversion and added discs to the rear (Detroit Locker)..

[@mikemacpherson7135]

Holy crap!! Lol....I’d never break something that strong...! What a build!!

[@willd7533]

The music after 3:45 is perfect, it was like watching an episode of How it's made! I have no idea why I'm watching this either, ruined my nap lol

[@wayalife]

LOL - so glad you enjoyed it :)

[@markhampton3599]

I have never seen anyone take so much effort into there product !!!! Thanks !!!!

[@JeepFanTony]

You can really see the quality of this product as its being built. One day I hope to have a couple Dynatrac's under my JK. Thanks for producing yet another great video...

[@wayalife]

Designed, made and assembled here in the USA. You really do get what you pay for when you get a Dynatrac ProRock axle!

[@markrich3271]

You know what I find cool . The machines there using . Just goes to show Grab an old Bridgeport with a proto track a lebond , monarch , rockford lathe and go to town . Nothing here was to horrible hard to do . Great work .

[@cannedham3774]

sure is a beautiful thing to watch how its done with all the right tools and equipment! nice work!

[@eddalbigermanokaiser7204]

No hay nadie que los pueda superar. En particular ...se q nunca voy a poder tener uno...pero no saben la satisfacción que trasmiten ustedes al verlos orgullosos del lugar donde trabajan y ver los excelentes e insuperables materiales. Dinatrax es lo mejor!!!

[@koalakoa]

Production quality and voice over is like an episode of how its made. Haha Looking forward to putting one of these with the 60XD on my JL

[@wayalife]

LOL - so glad you enjoyed it :)

[@eltonzhukov2079]

This thing is cool enough to the point where even if I didn't have a use for it I'd buy it just to look at it.

[@MrEndlessRC]

Teach me!! Let me be your protege. Beautiful work, something to be proud to stamp your name on!

[@dozer1642]

I was always told not to put grease on a bearing that will be in an oil bath (pinion), It seem like it wouldn't matter but I've been chastised by mechanics for even suggesting it, but I see you guys do it. Awesome video. Even more awesome axles.

[@BullittOutdoors]

I noticed that too as I have always packed bearings on Class 8 trucks. A lot of guys freak out over it, then again I have never had comebacks from burned up bearings, they have.

[@gr8ful68]

Holy mother of all axle shafts!!! Uber cool video as usual.... Number one fan here and I don't even drive a Jeep, but I do love all things four wheel drive with loose nuts behind the wheel. Anxiously awaiting your next effort.

[@apexpredator_jku]

Rubicat was always my fave! I know she's in good hands with her new owners and looking forward to seeing her up close now that she's a regular at my playground of choice, Rausch Creek!

[@DontGetBoard]

Haha I learned something from this video, aside of how the axle is built. I had thought of using a plastic spatula to fill the hub with grease! Looks so much easier than and cleaner than using my hands..

[@blck04gt]

I missed your videos! Don't go on a hiatus again!

[@wayalife]

We'll try harder to stay on top of things.

[@jackhook4192]

Awesome video my friend. If I ever break my Dana 60 full floating axels I will step up to these.

[@runeski74]

im a new jeep owner, and i just cant believe how much money everything costs for jeeps! Its like buying parts for my harley... only twice as much. Awesome video and even awesomer axels!! im now subscribed!

What a strong looking axle...!! Thanks for the video tour Eddy...!

[@hockeymann88]

Impressive. Looks like it can take a beating.

[@alejandradelosreyes4598]

Dynatrac makes amazing axles!

[@MNTrailRiders]

LIKED! and had SUBSCRIBED years ago. I really enjoy the voice over and explanation - I'm not literally going to build one myself but great to see the engineering and craftsmanship going into the product. See ya on the tail.

[@roberthein2156]

Thanks for showing me ,now I can go ahead and build one, right? Think I'd let you guys do that!

[@BolsonaroPresidente22]

Wow is really great how it's done video! it is easy to see that they are professional. they are fast, very accurate and on them.

[@BennyTygohome]

That is amazing. Thank you

[@WhiskeyTuber]

Was waiting for someone at the end to be like "aaaaaaand that'll be 8 grand."

[@redrobin3367]

I agree, for as much as I'd pay for one of these axles, I could do a lot to my vehicle, but I know for a fact that these axles are worth every penny

[@vikp6115]

James Lowell they sure are bullet proof , but 90% of all those people who put them on their Jeep's , drive on paved roads to Walmart grocery shopping , that's as much of a harsh use they ever see. :) just like those LED light bars they on the trucks but we all use them once in a blue moon

[@michaelcuff5780]

James Lowell your probably not that far off! Lol!

[@tjcook9464]

James Lowell A little more than 8 grand probably haha

[@biginuf2689]

0% of people that buy these are mall queens. those assholes just run 40s on stock axles.

[@deusmarbento7192]

Parabéns pelo o belo trabalho de vocês. Que constrói. Toda estas peças de carros.lindo trabalho de todas.parabeéns. um abraço do Brasil. A todos os trabalhadores.

[@dagooos]

Those very impressive axles! Great idea showing how they are built. First class!

[@Garth2011]

Nice review of the process. Great product ! Maybe drill and tap the air lock hole before the assembly goes to the final wash and paint process.

The quality of the work is impressive, and I would surely like to have one, but I am afraid its just not in the budget, my rig will have to make do with a salvaged Dana 80 and a few upgrades...

[@lossantoscity3249]

Those Red Threadlock are a devil's advocate. If you don't heat em up real good they won't come lose.

[@tubewaldo]

I would love to build those axles every day

[@Matp345]

Incredible craftsmanship. Real work of art when they're done with it, probably $7,000 an Axle though which puts them Way Out Of Reach For Me 😟😭😭

Hola amigo no me pierdo tus vídeos son los mejores Saludos desde Chile 👍👍👍👍👍👍👍👍👍👍👍👍😎😎😎😎😎😎😁😁😁😁😁😁😁😁😁😁

[@tutekohe1361]

This is the kind of axle Toyota should be putting in LandCruisers.

[@RichardJCurtis]

Very very nice video Eddie. Its soo expensive to get those axles here in South Africa, most of us are still running stock 44's with 37's. Going to 40's isnt really an option on stock axles here.

[@wayalife]

An axle like this is really meant for guys running really big tires and with really big horse power.

[@RichardJCurtis]

we have some guys here that have done V8 Hemi conversions, even one to a Lexus V8. The 3.8 at this altitude suffers. I dont need D80's but a Dana 60 or even a pro Rock 44 would be great.

[@alessioandreutti7138]

This video is quiet bit pornographic ;-) I can't buy it but is like a piece of art

are most E-brakes drum brakes? that was awesome to see how e-brakes are designed to live inside of one of the disk brakes.

[@Garth2011]

No, not all but this is one design you will see on most SUV's or heavier beefier vehicles. The brake rotors and brake drums are all one the same.

[@manbearpig2164]

awesome video

[@Ngryn]

awesome team of workers building a great product - well, it looks great - i dont actually own one. I'm concerned for Ashton, he is acid washing the axles with no gloves or eye protection on....... when he goes blind, I'll come work for you guys if ya give me a deal on the axles..... Great video (and yeah, i'll wear PPE)

wow drum and disc brake in one axle? thats cool

[@michaelteeple8704]

Most dont know whats involved in setting up a good diff. Ring and pinion alone can take hours. If you dont have over sized bearings to set up shims its a nightmare. Ide hate to see the bill. I bought currie 9s front and rear for my cj 20yrs ago and spent more than i paid for the jeep but its nice to fix a problem once and for all. It would take serious abuse to break a dyna 80.
