Cost to regear from 3.73 to 4.56

I like running my 33x12.5x15's but can't when I'm heading into 30mph winds in the Texas Panhandle trying to maintain 70-75 or pulling my 2800lb travel trailer with no wind at all at 65. Just can't do it without screaming in 3rd or even 2nd gear.

When I put the stock 17" wheels and tires back on it's "okay" but with those headwinds or pulling the trailer it's still spending a lot of time in 3rd at 3,500rpm. If I manually bump it up to 4th it'll drop to around 2400rpm and will barely hold speed and giving more gas doesn't cause any increase in speed.

I'm thinking a mild regear from 3.73 to 4.56 would let me run my 33's with strong headwinds but no trailer and the stock wheels/tires with the trailer just fine at around 65-70mph in 4th.

So what's the going rate for a regear like that?

I believe most of the cost is the actual install, so it may very depending on who does it.
Supposedly its not too hard to do but time consuming.

I do - I use a FlashCal and set if for measured diameter and then I fine tune it further so the speedo matches my GPS at 70mph.

Got a quote from a reputable shop here in Austin for around $1500 - $600 for the gear sets and $450 an axle.

Everyone's numbers seem to be about right. My suggestion would be to go with the master install even with a newer jeep. Many shops won't do it without a master. Also you are more likely to have issues going with the minor. If a bearing is slightly off or something is slightly bent you end up with noise.

Thanks for the info!

The local shop did quote a master install kit as part of the $600 price for the Yukon gear set.

I paid 2k, but the 4.56 I think is to put the axle ratio back to factory specs for 35s. There are charts somewhere on this forum that talk about how to put it back to factory for the various tire sizes.

just had Yukon 5.13s w/master install kits from River City Offroad ($600) installed for about $600 but I also had a rear locker upgrade that added a few extra hundred in the labor ....figure approx $750 $1000 in labor @ABOut 10-12hours for gears depending on who ya know or where you trust to do it right....to reiterate, gears +labor for a day total cost about $1500 total ....I'm sure there are cheaper and more expensive depending on where one is geographically ....EVO has that $999 regear special if ya live out West....ask other local Jeepers is how I found out a quality shop ....

If you don't mind me asking, who did your install? Looking for a reputable shop in Nashville area.

The "best" shop here changes $2,200 total. I'll call around and check some more. That is a pretty high price but these guys are pretty much the best and help out Jeepers a lot in general- sometimes by even convincing you to not buy stuff. :) I'll check with a few more reputable places though. The 4.10s are getting harder and harder to bear.
