Arbs
are the best diff out there. In my car I have mega HI9s fr and rr
with a detroit/spool combo. If arb 9in diffs were more reliable,that what I would have
at least in the rear axle.

I would stay away from cv 60 shafts!!!!!!!!!!

Other than Bobby's not selling them, why would you stay away from CV60s?

They turn smooth but you can't set the steering past 42 degree's unless you want to blow them up.

And they click, LOUD sometimes.....not that it has any negitive affect.

Makes me think of the song' "Click, Click, Boom"...:redneck:

So, what would be the best way to go beyond 42*???

Mine never failed

A hp 60 in the rear should be just fine as long as you are not some punk kid that thinks one should hold up to 49" tires being bound up while doing neutral drops to try to get them spinning.

Love my rear pro-rock. 5 years of beating and still good..

Clark · Sep 17, 2009

can i use my RD35's in the dynatrac centers? or do i need RD36?

Edit: Yes, i can use them, as long as i use a 4.56 and up. I'd need an rd36 for anything numerically lower than that.

I'm going to have to take my chances, it was that or the 9", and i want to run ARB's. So it's a catch 22. I went back and forth, on that a couple times, maybe i'll regret it maybe not, were you breaking rear gearsets on your old buggy?

Money Mark · Sep 17, 2009

Assholes.....opinions......everybody's got one.

Dude......I have STOCK D60 junk yard CRAP for axles, front and rear steer and beat my **** harder than 99.9% of folks out there. Take it from me.......Dana 60's are :tits6: Your ProRocks will be fine, just fine.:;

9" Thirds are :rb:

Clark · Sep 17, 2009

here's the most incriminating evidence of the 9" ARB's "issues" for anyone wondering what the big deal is. And i'll be on 42's with around 400HP, and similar weight, maybe less.

9" vs 60 in pictures (these are all ARB parts, nothing stock):

60 side gear, 9" side gear, 9" locking collar.

60 side gear sitting on 9" locking collar.

Flipped over, 9" side gear in its own locking collar.

Same thing, but with the 60 side gear sitting on the 9" locking collar.

If I'd not abused my rig in comp, the 9" stuff probably would've lived a good long while; if I'd treated it as a race car (put it on a maintainance schedule and torn down everything appropriately to preemptively fix stuff before it broke) it probably would've been fine in comp as well; if I'd put it on a diet, or gone to smaller tires, same thing, probably would've been fine.

Instead, I bigger-hammer'd it, went to 60's (that 60 side gear, is the standard 35 spline one; I went to 37 spline) and went on neglecting my own maintainance.

Junk yard 60s work awesome, sometimes better than aftermarket stuff. my biggest point was don't do the cvs. The company that builds them are a pain in the ass. I would recommend the spidertrax axles over the rest. For the money spidertraxs prices are close to Alloy or Superior but their quality is much higher and they turn 50 deg. When the steering geometery is properly set up for 50 deg a car can do some amazing things.
