37's on a d30?

So I pretty much killed this thread yeah? Lol.. Quoting Anchor man is usually a good sign..


Lock Down or Get Locked Up
 
So had a good conversation about this topic today. Basically as long as I didnt lock my 30, I would be fine. Now again this is with the understanding that everything breaks...

Oh and I saw this right after said conversation...
 
Locking even with chromos?


Lock Down or Get Locked Up

Locking my 30 or upgrading my shafts were never in my plans. I did spend some $$$ protecting it, but that is it. All future front axle money is going towards a PR44 (probably after I get my son through college it seems... :grayno:)

I personally though, want my axle shafts as the weak link since they are the cheapest and easiest to replace. All locking and chtromos is gonna do is make your R&P the weak link and BAM!!!

Just Another 37s on D30 thread

Sorry to start another thread and probably answer questions that have been asked already.

I have been quoted $8000 for a pr44 fully built with ring pinion locker rcv prosteer ball joints so on

Now my question is can a D30 with 4.88 ratios handle 37s In a 3.6 pentastar that Bering said either sleeved gusset housing or a terra HD30

Or am I just better off saving my money and just be happy with 35s on my current set up

And yes you can run 37's on a 30 axle but plan to wheel, it can break and not recommended. The same with a stock front 44. However I'm running the stock front until it breaks.

If you're going to run 37's, the ratio you really want is 5.13's but, I personally would stick with 4.88's just for the added strength. I would forget sleeves but add gussets and, I would get a set of chromoly shafts with full circle clips. I would NOT waste your money on a Tera HD30. It's the internal components that fail that will leave you high and dry and NOTHING inside is changed with it.

If it were me and I was on a budget, I would stick with your 35's and have as much as you can with them. If down the road you can afford to upgrade, do it at that time. There haven't been too many trails out here in the western USA that I haven't been able to take on with confidence running 3" of lift and 35" tires and that includes the Rubicon.

I watch a lot of YouTube videos and it seems Australia is more prone to sand, dry riverbeds, corrugations, etc. Rocks don't seem to be as common as they are in the western US. It seems that 35s with some great suspension will suit your needs better. Just my opinion based on primitive knowledge of the land down under.

this is very true. our terrain is far from what you guys get :( but there is fair few rocky places around that is kind of what you guys get but a much smaller in size

37s with dana 30

Hello Wayalife, I'm running 37 inch toyos with a purejeep truss kit. Do you guys think adding a sleeve kit would be worth it? Or is the truss kit good enough to strengthen the dana 30. Thanks!!!!

even the truss is not strong enough to keep the d30 from bending at the housing. i would add C gussets and call it a day. then start saving for a PR44.
