Building a Dynatrac ProRock 60 Front Axle for a Jeep Wrangler : See How it's Made

When you need to have absolute confidence in the quality of your axles and how they'll perform out on the trail, few companies can give you the kind of peace of mind that Dynatrac can! Their ProRock 60 axles are legendary, made 100% here in the U.S.A and engineered entirely with new off the shelf components that are designed to work flawlessly together and without the need to use recycled, refurbished or salvaged parts from junkyard axles. Of course, the ProRock 60 is also the only axle with a profiled differential that offers well over an inch of ground clearance and to top it off, Dynatrac is the only company that I know of that offers a no-fault warranty so long as you properly service and maintain your axles.
Needless to say, when it came time for us to upgrade the front axle in our 2007 Jeep JK Wrangler that some of you know as Moby, there was no question what axle we wanted to get. Fortunately for us, Dynatrac was kind enough to invite us down to their manufacturing facility in Huntington Beach, CA and see how our ProRock 60 front axle would be made from start to finish. After watching this short video, you just might want one too!

what a very cool hot work

[@dextersuarez9948]

This is amazing watching this 13 years later!

[@wayalife]

@Frdmstang i upgraded the locker to an arb and installed a set of 35 spline shafts. i also had to install wheel adapters so that i could run 5x5.5 bolt patern wheels.

[@rustyshackleford359]

Badass. I wanna work at Dynatrac so bad!!!. Awesome workmanship and a Execellent product.

[@wayalife]

@rickyp32 the axle tubes are pressed into the center section and i'm pretty sure that alone is pratically enough to hold everything in place. the "plug" or rosette (NOT spot) welds ensure they won't.

[@markhampton3599]

Just great to see people who care about what they do !!! Thanks !!!

[@cuda2266]

@rickyp32 i think if they had fully welded up the centre to the tubes it would have made the axle potentially weaker as the heat from the welding would effect the metallurgy of the tubes & also act as a stress riser

[@78k5]

Nice welding from the first dude! Steve BUILD ME A D60 please!!!

[@danilocynepppiloveyoumotas2401]

super nice

[@Stuka87]

Dynatrac builds awesome axles :)

[@Islandhuntingandoutdoors]

Very interesting to see what goes into building one of those

[@wayalife]

@556firepower we purposefully have manual locking dynalock hubs. even if you could get it shift on the fly, i wouldn't want it.

[@theoriginalmodz]

another great video guys keep it up

[@jbrunsonjr]

You lucky, you!! I need some deeper pockets! Thanks for sharing!!!

[@gerryscott876]

As this is an old video I trust you have updated your welding procedure for those 4340 tubes. Pre and post heat is a must.

[@jackkrinkov9273]

The axle tubes aren't 4340, they are DOM. The axle shafts are 4340.

[@gnr8ionx]

Great to see ARB diff centre in there :) Go Aussie!

[@k5gsxr]

great video

[@bruce-bruce7975]

Awesome video

[@wayalife]

LOL - Thanks! Glad to hear a video that's over 10 years old is still something people can enjoy :)

[@Usmanthemecano]

that boy can weld!

[@guitartank11]

What beautiful welding man...

[@ChrisLawley43]

like the nice little down hand weld he was doing on one bracket lol guess it's strong enough for it's purpose

[@LuaiADV]

DAMN!!... If I didn't have those right now I would be steeling to get them lol great video as usual

[@ZuranMarine]

I love u and all the jk project!!!!!!!!!

[@jeepinreo]

@rickyp32 they did 6 plug welds. plug welds are very affective. turning the amperage/voltage up high so you get good penetration. When ever they sleeve and axle they use plug welds....

[@wayalife]

@braaup oh, you could say that. depending on the kind of shafts you get, u-joints, type of locker and things like that, you could be looking at about $10k or more.

[@chadgdry3938]

noob question: what did you order for them to build. Clearly the housing, axel, knuckles, disk breaks... make/models...?

[@brisonp6148]

Nice video keep them coming!! You gotta pay to play save your money if you want a Dynatrac!!!!!

[@theoriginalliquid]

wow that welder is an artist.

[@devonabraham3588]

i guess it's kinda randomly asking but does anyone know a good website to watch newly released series online ?

[@matthiastyson6732]

@Devon Abraham lately I have been using Flixzone. Just google for it :)

[@jeffersondavid5679]

@Devon Abraham Try flixzone. You can find it by googling =)

[@rodneyty4361]

@Devon Abraham i use flixzone. Just google for it :)

[@zacharyalonzo6164]

@Devon Abraham i watch on flixzone. You can find it by googling =)

[@Bl17Z90]

Is the Dynatrac 44 a lot better than than the stock dana 44? and would the dynatrac 44 support 37's or should you still get 60's? And last question, do you need to do anything extra to the dynatrac axels to make them support 37's like gussets or is that just something you do with the stock axels?

[@556firepower]

Did you have to go from shift on the fly to manual lockers with this new differential, or is there an option to maintain the ability to shift on the fly with the Dynatrac?

[@wayalife]

@WillDaBeast696969 depends on how big of a tire you are hoping to run and how hard you plan on wheeling your jeep.

[@wayalife]

the dynatrac prorock 44 is a lot better than a stock 44 and no, you wouldn't need to do anything extra with it to run 37's

[@chalinp4886]

Bad ass

[@wayalife]

@WillDaBeast696969 well, you would need to get the right brackets installed but, i don't see why it wouldn't/

[@Frdmstang]

What is done to the stock rear axle?

[@Willybillay01]

will these axles fit on my 98 chevy silverado? i want to do a sfas

[@wayalife]

@ThatHmoobGuy depends on what all options you get but, you're looking around $10k

[@4X4OFFROADGUBBIO]

che prezzo hanno 2 ponti posteriore e anteriore?

[@nswsparky]

big money

[@Willybillay01]

@wayalife ok cool. if not these axles what would u suggest

[@rickyp3218]

For that application i.me sure it would hold up i come from a pulling back ground and gm trucks and they new 14 bolts are plug welded and iv,e herd stores of some them rolling there center sections i don,t know about the new dana,s if there plug welded

[@changdae11]

the tall guy in the shorts shorts and white t shirt is my stepdad... no lie! godaddy

[@TheHooligan-5]

How many times did you break your dana44 before you got the 60? How well did it hold up to the tires you were running (I believe they were 40s)? I've got dana44 with yukon chromoly and I'm running 38 inch crawlers and I'm always worried that I will break them on the trail and be screwed. Thank you!

[@Ben-lo7cy]

The Hooligan 4 have you broken a shaft yet? I'm about to be running same thing

[@chris-yk4qn]

What wheels are those ?

[@trailstomper93]

How much did u end up spending altogether?

[@aseppurnama5079]

29/12/2019

[@ThatHmoobGuy]

how much for those axles

[@robkilleen5997]

What's going on with that red dodge in the shop...?

[@rockshockoffroad4x43]

Do you break the Pro Rock 44 or just the 44 that comes with the jk

[@wayalife]

This is a really old video, 10 years old in fact. There was no such thing as a ProRock back then. We broke our factory DANA 44 front axle.

[@ruquik]

Project Jinxy @ 6:44

[@rickyp3218]

did any one notice that the center section was only spot welded to the axle tubes you would think they would put a few passes on each side

[@jackkrinkov9273]

You have no idea what you are talking about.There is no such thing as a spot weld. The axle tubes are pressed and plug welded with .045 ER70s MIG. And they arent going anywhere.

[@michaelramirez2382]

Dear Santa,

[@Willybillay01]

@wayalife seeing as i dont have a jeep....lol instead i got a silverado 1500. haha and im gonna run 40s

[@radcoolade1481]

Gladiators on a 40s are breaking 60s. When is 70 coming out and I'm talking front axles.

[@wayalife]

Currie makes one. Give them a look.

[@gussrestu]

jhon myung???

[@tylerspellman9571]

Want

[@TheDennyvu]

umm did he just impact that pinion nut on? can you say too much preload?

[@wayalife]

none what so ever

[@admantiom1848]

An impact wrench should never ever be used to torque the "pinion" bearing. The damage to the bearing races are imminent, you will never see this in a Dana-Spicer videos. Dynatrac should know better than that.

[@ryanfreeman125]

lol no. The torque needed is way more than that impact can give. He torqued it by hand with a torq wrench which they didnt show. good catch tho young feller
