Same question: What are you doing that a PR60 won't be enough? Catching a lot of air in the dunes??

Maybe Dynatrac can comment as well. I figure a PR60 is enough for 40's. Going larger, or just more abuse?

 

What we have seen over the last few years, that 40+ tire, V8 conversions and a lot of weight can cause issues.

Impressive!

 

I know this thread is old, and I've been reading Dynatrac's website looking for the answer, but I am not finding it. What size rim and bolt pattern do you need to fit up to this axle. Also what driveshaft do you need? I'm looking at Adams Driveshafts (1350 Severe duty) and wondering if they would be strong enough. (I'm trying to price this all out before I max out the credit cards). I live 20 minutes from king of the hammers and after 8 years of watching I'm ready to build my New JK to Handle the abuse of the Hammers.

 

it has a 1410 yoke (only 1410 and 1480 are available for a dana 80) and you need a 8x6.5 bolt pattern. 9/16" studs and you need 4.5" center bore.
The Artec hat needs modifications to fit right and is the only one available for the PR80 most notably it has the wrong size bolt holes in it an needs to be drilled out. The axle is pure beef and should hold up to just about anything you can throw at it.

 

They are 8 lug x6.5, if your going big they you need 17"or larger rims for 40".
I'm running 17x9 4" BS
1350 CV at the TC but you need a 1410 at the axle end.

 

I had to google Artec Hat, didn't realize you were talking about a skid plate. Thank you for the Reply, I plan on running 40's. I've been trying to figure out the strongest way to go, I figure spend the money up front to build it right. I know I can build cheaper but honestly know things will break, so mind as well do it right and plan it out.

 

its not a skid plate, it is bracket that allows you mount your control arm brackets above the differential if you are doing a three link or double triangulated 4 link.

Okay, that makes more sense. When I googled it the first time it pulled up a skid plate with the same name at 4 wheel parts.
