Yeah - too high. That would be like $2k in labor- it does not take 20 hrs at $100/hr to install ARBs ... (and i know a little bit about ARB installs - i use to be part-owner of a company that did them). Bring it to me and I'll do it for $1k labor in my garage.
I got a quote to have ARB air lockers installed in my 2012 JK sport two door. Dana30 front and Dana44 rear. That seems WAY high. Any thoughts?
No my friend that is right, and you need to regear also to at least 4.10 or it is a dog and will get only get worst with bigger tires! And that will cost you around 5K total. You would of been way a head to buy a rubi and have factory warranty and all. I made the same mistake when I ordered and bought a sahara. $3800 dollars later I have a front Elocker and 4.88 Yukon gears. Did not lock the rear as I like the full time trac loc better and keep it in. Just take it back and get a rubi and you will be glad you did.
To KSCRUDE's point ... If you're talking gear swap AND ARBs, that's a different story. $4k-4500 sounds on.
I would disagree with KS on the trac-lock, though ... but, it's personal preference. There are positives and negatives to each and 'one' DOES NOT 'fit all'.
You are right C90, as a trac loc is not a full locking axle, and they both have different applications. It just depends on your usage. 99% of wranglers owners (me included) would do just fine with open front and rear axles with four wheel drive as it works very good in most usage. I have had a truck or two like that and they do pretty good in level mud and snow. Not too good on very unlevel terrain or in off canter situations.
