1993 RRC axle conversion

Hi all,

I recently bought a 1993 RRC from Doug here on the forum, and am about to swap out the diffs for ARB Lockers. The diffs and axles that are in the car are the older 10 spline, and the ARB's are the 24 spline, so I am looking to do the axle upgrade to 24 spline, but need some help on the parts I'm going to need to do the conversion, other than the axles. Any help is appreciated!

Is this Doug's 350 Chevy RR conversion?

Contact either Ashcroft or GBR to source the axles and they will make sure you get the correct ones. You will also need to change the CV joints.

Ummm.... The 32 spline CVs ARE the problem. The 32 spline is very small and very weak. Installing a locker and leaving those in there is insane. If it is too much money, leave the front open until you can afford it.

Yes, but that 350 is still a lot more oooomph through those CV's...(if it is the Doug/350 truck)

This is Doug's 1993 Chevy 350 conversion.

What do I need to change the CV's? I'm trying to pull a parts list so I can do front and rear in advance of the winter when this truck will really be put to its paces.

Ok, then its a 350---->R380---> LT230

That will lead to more drivetrain shockloading.

I've busted a few CV's in the past(Rovertracks) and then went to Ashcrofts.
But I'd get a HD type of CV in there...

I blew up 2 of Keith's aeu2522's! I wasn't impressed.

No, you want aftermarket chrome-moly CV joints unless you like replacing broken joints on the trail.

If those era axles have the narrow hubs, then you can probably use the later model style. The Rovertracks kit is the cheapest. Not sure what else is need to make it all fit.

Don't confuse the guy... Rovertracks closed down years ago. The "Rovertracks" CV joints you can buy TODAY are chrome-moly and made in the same place as what Ashcroft and GBR use.

Yes.
Ashcroft and GBR/ same chromoly CV's.
Keith/Rovertracks=closed

Personally, I would not run any stock cv(even a 2522) with a 350 and a manual trans.

Another option is the Tibus chromoly axles/cv's available through Lucky8.(German, I think?)
A little cheaper than the other 2 places I think.
And you can keep the existing hubs and spindles.
I cant say how good they are or aren't.
I am running some Tibus rear axles at the moment...

Lucky8 are having Rovertracks Chrome moly CV joint and shaft kit made. It is the lowest cost option.

They are all made by the same company but they are all not identical.

Lower cost than the Tibus?

Not sure why people can't look on their own...

Lucky8 Llc. - Take the road less traveled...

Looks like the Tibus ones are bit cheaper. I would keep a grain of salt in mind with his stuff.

I spoke to Bill at GBR and he suggested going with stock on both front and rear. His comment was that unless I am doing serious rock crawling and am a throttle jockey, I should go with stock front and back so that if something breaks, it is the axle that breaks, so if you break one you can still limp home.

You explained 350 with 35" tires? If so, that is horrible advice.

255-85-16 Maxis mud terrains for tires. He said engine size didn't matter since you only use the amount of power that you need, not how much you use in reserve.
