Default Will an "old" 8" ARB work in a high pinion diff?

I'm looking to move to a HP front diff, but the ARB I'm using is from the late '90's. Do any of you know if they've changed over the years and, if so, is one of my vintage likely to work in a HP? Open 4.10's are pretty common, and I'd like to use my existing locker to keep the cost down.

I might have found the answer... Randy, did you ever do that swap?

Sure.....you can probably get all the parts needed for your mini truck axle here.

Cool. I was thinking of ordering one of the Trail Gear "conversion kits", as that looks to be less money than a $300 open HP diff, HP gears and setup kit. Had any experience with those? I'm not a big fan of trail gear, but the reviews of these online seem good.

Thanks,

Mark

I can't get that link to open. I bought a new HP carrier from TrailGear along with R&P, locker, etc and assembled it myself.

I bought tons of stuff from TrailGear and it was all good quality stuff. I never broke anything and when I had stuff I needed to return, or a warranty claim on a power steering pump, their customer service was great.

Thanks Randy. I fixed the link: It's actually an old thread of yours. Their conversion kits are kind of like what you bought - HP housing, gears, setup kit, etc, for one price. This is sounding like the right way to go...

There have been changes in the ARBs and the new ones are better... but I am running an old one in my HP. Yep it will work fine.

You may want to update the O-ring design. The newer style that retrofits on the older design is somewhat better. The newest design, which does NOT retrofit, is (AFAIK) better yet.

But paid for is paid for.

Good idea. Did you just call ARB for the upgrade?
