Building of a Dynatrac ProRock 80 Full-Float Rear Axle

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!

[@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.

[@onebridge7231]

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

[@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!

[@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! : )

[@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]

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

[@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.

[@nickjovanovic5258]

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

[@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!

[@MrEndlessRC]

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

[@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..

[@cannedham3774]

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

[@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.

[@jackhook4192]

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

[@josephnovak3485]

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

[@markhampton3599]

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

[@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 :)

[@mikemacpherson7135]

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

[@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 .

[@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!!!

[@ortiz73caify]

What an awesome video I want a Dynatrack axle. I love the quality and craftsmanship.

[@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.

[@alejandradelosreyes4598]

This is amazing craftsmanship! It's a lost art, unfortunately. Thanks for sharing!

[@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!

[@xmo552]

J ust E mpty E very P ocket

[@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.

[@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.

[@dagooos]

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

[@NigelNaughton]

That is so sweet! I don't even own a jeep but a FZJ 80 Landcruiser. Really happy to see you making more videos again.

[@wayalife]

Thank you, we have every intension of making more.

[@patrickmurphy3]

Wayalife Jeeps, Tools and Machines, Oh My! Love the video Sir!

[@dtmccurdy11]

Very impressive machinist work right there!

[@dieseldc409]

Amazing work and pride in your work. Won’t ever buy one b/c I’m always broke but I can always dream!

[@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.

[@Nielubie78]

Handmade in the USA! Love the video.

[@infokiz]

That was awesome! Looking forward to more videos like these.

[@wayalife]

Glad you liked it. We hope to make more like this in the future.

[@roberthein2156]

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

[@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.

[@JoseSanchez-mu5yo]

Awesome video Eddie! Thanks sir... I agree your videos just keep getting better and better! Keep up the great work.

[@wayalife]

Thank you, we're so glad that you enjoy our videos.

[@joshsstuffs5877]

Excellent video, guys.

[@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 :)

[@hockeymann88]

Impressive. Looks like it can take a beating.

[@bowtie-man]

I was sold on this jeep when I saw the 6.2 emblem booyah👍👍

[@camronbay1]

Excellent craftsmanship.

[@BennyTygohome]

That is amazing. Thank you

[@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 😟😭😭

[@buddydawson8875]

Precision in Excellance!

[@peterf.4268]

Epic vid.

[@joetuktyyuktuk8635]

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...

[@florentinorenteria588]

Great job

[@Bowmaster16]

awesome video!! any chance we will get to see it installed on your jeep? or any jeep for that matter.

[@6000MPH]

Hand made in the USA, that's what I fought for. Great job, great video!

[@AndrewBrowner]

awesome video with lots of good details, but what exactly is "high clearance" about this axle

[@user-nk4hg3so4c]

Класс! Работа профессионалов! Жаль у нас Сибири такие не делают.

[@mondeacid5610]

Truly a work of mechanical art, a real beauty, nothing beats MADE IN AMERICA !

[@MarcoAAOrtiz]

Really very well done.

Thank you :)

[@Ryan_Atomic]

wow! amazing! gj to all of you!

[@rsbrehm]

Wow. Time flies.

[@wayalife]

LOL - hard to believe for sure!

[@rsbrehm]

@@wayalife I remember watching this during work the day y'all posted it. :O

[@11Twiztid]

I would do so many things I would not be proud of if I had the skills to build one of these

[@9929kingfish]

11Twiztid. Like?

[@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.

[@monkeypenllwyn1]

When you put the pinion in the lathe to turn its shaft you just slung it in a 3 jaw ? Wouldnt you be concerned about concentricity with the pininon gear seems it wasnt clocked ?

[@GaryGalmin]

Love your guys videos, especially with the Jk experience ones. Why do some of them get flagged within youtube? I could watch like 2 out of the 4 or 5 videos of one of your last posts.

[@ciasteczkowypotwor4553]

milo sie oglada taka robote nam w pl daleko do tego

[@Sergiotunes1976]

belissimo trabalho.,parabéns...

[@nashitsiddiqui9626]

For Hypoid pair which ratio configuration is used.

[@MatkatMusic]

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.

[@jollibeetilao3604]

Surely it will conquer rocks!

[@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.

[@jimmallery294]

Very interesting!

How many does It cost? I would like to buy one of this. Thanks for the information.

hey I am designing a tilting cargo trike I plan to add a samagaga differential to it, and I am having a hard time designing a proper full float system as you have shown here, could you provide a link to a site where to get advice?, or are you up for providing this advice?
