Dynatrac vs. Rockcrusher

[5150Jeep]

Excluding the price which one is better and why? Also those who are running 40's what gear ratio do you have?

[UCTJ]

Well as far as I know Rockcrusher only makes the center section which means youd have to build the rest the tubes inner C's and knuckles, which means that you can use whatever you want Crane innder C's knuckles etc and you can build em with kingpins.

The Dynatracs are all built by Dynatrac and lots of people dont like the fact that they use unit bearings and ball joints instead of kingpins. Maybe that will help you out some....

And for those running 40s that depends on engine, tranny, t-case its too broad a question to answer that question alone. Also what are they using it for rocks, mud, sand etc when you determine ratio in addition to the above....

Dynatrac has been around for 15+ years and I doubt they are going anywhere. Rockcrusher has only been around for a few years and has already gone through 2 or 3 or more different US distributers. I've heard Dynatrac's warranty is pretty good. I would also look into Currie.

Dynatrac does not use unit bearings, they use the Ford style spindles and hubs, they also have thier own 40 spline hub, spindle and stubs. You can also have Dynatrac build using Dedenbear or Crane outers. Currie usually uses Superduty unit bearing.

Very true, and I know that they have build a front D80 with either ball joints or kingpins if thats an issue for anyone. Currie does makes some very nice axles as well, also you can look into Sunray Engineering. But if you just look at the Poly Performance YJ thread in this section you can see some of the nice work they do with a Dynatrac axle.


And I stand corrected on the unit bearings.....Goat1 knows better than I.

[5150Jeep]

Yeah, that yj they built is tits! I think I am going with dynatrac due to the 40 spline and the extra clearance pumpkin they have. Thanks

What about dynatrac's new Dana 80, now thats pimp....

[Po' riggity]

I like dynatrac's stuff, and its nice, but its pricey in comparison to some of its competitors.

Very true. There are a lot of other axle builders out there. What about a Sunray 1550? Talk about blingity bling! Or maybe a custom Diamond housing and a TrueHi9? Lots more out there than just a sparkling D60...

Dynatrac's customer service has been great for me (44 and 60). They are definitely $$ but then I don't have time to fool around with a vendor that you have to stay on top of. They also keep a record of the axle they built for you. You can call up and they will look up their build sheet and tell you dimensions and components used if you have forgotten.

[LazyDog]

rockcrusher makes center sections, and inner Cs and ball joint knuckles. It's all VERY stout stuff.

I have a dynatrac front 60. Nice axle, but I wouldn't buy one, if I did it all over again. I've broken the dynatrac knuckles and upgraded to the rockcrusher knuckles which have keyed hysteer arms. The rockcrusher knuckles make the dynatrac knuckles look like junk.

If I ever need another front 60, it will have kingpins, not ball joints.

[SLIPKOTJ]

I agree both are nice. I guess it comes down to what you like. Both are equal but the rockcrusher is alittle less thats about it. You can build the outers with whatever you want with both companies.

[cj8berry]

Does rockrusher have any type of warranty? I know dynatrac warranties it's stuff for 1 year from purchase.

What? Dynatrac won't build you a kingpin front d60. They won't even discuss it. I should know: I bought a front d60 from dynatrac. The dynatrac knuckle is not stout enough to hold up to hydro steering. I broke the dynatrac stuff running hydro and I've seen 3 other people do the same thing. Dynatrac customer service: yes, it's very good. They answer the phone and your questions and they deliver the axle on schedule.

The rockcrusher components are a lot more heavy-duty than dynatracs, especially the knuckles. IMO, rockcrusher makes the best ball-joint d60 knuckle. AFAIK, rockcrusher only makes components though. You have to find a builder to assemble/fabricate them into a complete axle or DIY.

Like I said earlier: I wouldn't buy a dynatrac front d60 again... because they won't build one with kingpins. I might buy a prorock center section and combine it with a set of crane inner and outer knuckles.... that would be a sweet front d60.

I talked to Dynatrac a few weeks ago and WILL build a HP60 with kingpins, but it will cost you. But you get what you pay for. They do push their ball joints but you just got to push back.

Where the hell is this? I havent seen it.

[Beast40]

I have a Dynatrac rear axle and they were great to deal with. They answered all my questions and even sent me pictures of my axle through out the build process.

Its in the latest issue of 4wheel and offroad mag...features the Dynatrac 80 front axle with a choice of either ball joints or kingpins......

[Gummi Bear]

Crane is developing a center section, and will be selling housings complete with their inner C's and knuckles soon from what I understood talking to the man there on the phone (I was inquiring about whether they build some knuckles for my EB D44) It should be a bombproof unit.

I'm a big fan of the Sunray goods, they're nice folks, and build great stuff. The 1550 is mighty stout, and if you still don't think that's enough, wrap your mind around their 1610, it's freakishly strong, and turns 45* with no loss of strength, anywhere!

Sunray or Diamond housing with a True Hi-9 and 60 outers...best of all worlds.

[Funkel]

Dynatrac really spends a lot of time and money working like hell to make the highest quality, american made product they can make.

They're a small company busting ass day in and day out to really offer the best possible customer service, product at a reasonable price.

While their product isn't cheap, they don't cut corners to make it less expensive. You buy Dynatrac and you get no short cuts.

That doesn't take away from the quality of others, but Dynatrac is an outstanding company.

[BrettM]

Hi9, Diamond housing, Dedenbear knuckles (or Crane), Longfield CVs... and a credit card.

[89yjguy]

Mad 4wheeldrive makes some killer axles.Talk with larry and he will make you whatever you want!! He is making me a rear custom 9inch housing,similar to the diamond housing,but better. I'm going with the true hi-9center,35 spline superior shafts,full float,arb,disc brakes,and drive flanges.It's going to be killer!!

Why are they better than Diamond axles???
