How much $$ to re-gear diffs

I just called my local drivetrain shop (they had great reviews) to get an estimated price to regear the diffs in my truck. I want to go from 3.42 to 4.56 and they told me it would cost $2500-$2800. Does this sound right? I was expecting somewhere around $1500 to $1700 max. This is almost $1K more than what I was thinking.

Labor should be around $250/axle. That's based on a 3-hour job per axle at a shop rate of $75/hour and rounded-up for sales tax.
Parts kits ("Master" parts kits, including all bearings, races, ring bolts and shims) are about $125/axle.
The actual ring & pinion sets are about $150/axle.
So that's around $1100 total, give or take. Let's say $1200.

If you needed a different differential carrier, they are average $150/axle.
So then you'd be in the neighborhood of $1400-1500.

If you were installing limited slip or locking differentials, there's no additional labor time or cost other than the differentials themselves (EXCEPT electrically or pneumatically-actuated lockers like ARB/etc). You would not need an open differential carrier in this case, but tack on the price of the limited slips/lockers. Then you'd be in the $2500 range, depending on the locker.

If you like this shop, I would ask for an itemized quote.
For that much, they are probably subbing it out to someone else and making $1k for their trouble.

Lol. I was quoted by a driveline place 8 hours for my rear and 10 for the front on 2017 HD. I almost fell over laughing... like really lol. My rear is a 10.5" 14 bolt which is honestly the easiest rear end on the earth to setup thst isnt a dropout style. Plus my new gear and bearings are already mounted to my carrier... So like 2 hours max lol... not 8. And that was at like $120 an hour to boot. Needless to say a buddy of mine and I are going to do it when we have time. We have both setup diffs before however lol.

You're in Vegas so things cost more.

There's a large off-roading community in the area so check around. There's bound to be someone who does it in their driveway. Where I used to live there was a guy who'd do it for $250 per axle if he had to do it with the axle on the truck. $150 with the diff out.

they probably feel that they can charge whatever they want because they know they have excellent reviews and everyone pays it without a second thought.. but that is pretty steep.. anything over 2k is a ripoff IMO. considering i did mine my self in the garage for $400 and here 40k miles later nothing is wrong with them. (only a 2wd, so $600-800 for 4wd)
