Sounds like the only thing your buddy would really not need is the ARBs sense he is planning on it only being a street cruiser. Those axles would stand up fine to the 38s so long as the Jeep sees no hardcore trail use. If you want to be a real friend, you should offer him 800-1000 for the ARBs, lines and compresser. You are still getting a good deal and that would give him enough cash to gear down to 4.88s. He should actually have somewhere in the neighborhood of 5.13-5.38s with those tires but I know 4.88 is a slow as you can go with the D30 and ChryCo 8.25. You do that and still help him with the gear install and that would be a good deal with a friend.

 

Alright thank you for actually replying about the topic. Can you gear up to 5s for the dana 30 and 8.25??? If so ill mention that to him. But from all I hear on the forum is either " chrystler 8.25 can run up to a 35 with out worrying. I was gonna go get him an 8.8 from the junk yard , weld up the brackets for him and. Help him install it. And he will be wheeling it. Him and I have got some end of summer wheeling trips since we get our license in August.

 

You should never "4wheel" with a tire bigger than 35s on those axles. I said he would be fine with the 38s sense you said he would just use it for street use because it looks cool. No you cannot get "5" size gears for the D30/ChryCo 8.25. Their limit is 4.88. Nothing lower is made for those axles.

 

Alright thanks buck ill let him know. He already overheated it in the dunes lol. Dug himself to the axles in sand! Lol just kept gunnin' it. And of course he's gonna 4 wheel it! Definitely is not built to be a street king lol would 44s all around be alright? Or a 44 up front and 8.8 rear be better??

 

44's would be pushing it with upgraded shafts and what not.

 

What do you suggest for 38s then??

 

1 ton axles.

 

Yep. 60's and/or 9". Lots of fab though.

 

What about 44s with upgraded shafts??

 

At the point you upgrade a D44 to handle 38's, you could of set your money aside for a D60.

 

D44s F&R or even a D44/8.8 combo would be pushing it for trail use....LOL...and especially sand dune use where he will be romping all over it. Those are all still basically 1/2 ton axles. For serious hardcore trail use and/or dune running with 38s he really needs D60s or a D60/Corp 14 combo if he wants positive insurance that he won't break anything in the axles when he romps on it with the 38s.
