I am contemplating doing this swap and found online the complete kit needed from Nitro Gears for around $1200. Is this about right? Is there any other kits/manufactures I should look at?

I have a local shop that is very good and very well known that said they will do the labor at $95 an hour and expect 7 hours on the project so that is essentially the whole swap for about $1850. (I dont have the tools or knowledge to do it myself)

Dealer I bought the truck from estimated $2800!!!

 

From what I have heard hear on FTE your estimate is close to on par. Will you be going with a locker for the rear or keeping existing?

Yukon is another manufacturer, Ford also has 4.30 sets available.

 

My dealer told me $2800 also.

 

Put it towards a new 2017.

 

Talk to the shop first but ask if they require you to have a full kit. If you are low mileage you don't need the bearings. I paid a little around $750 for my gears from the dealer. About the only thing you will need to get separately is pinion shims and a carrier super shims for the rear axle.

 

Mine was about 3k and am so happy I did it.

 

Great info. It really is a shame there are not more 4.30 trucks on dealer lots to choose from. I, like many, have had to order them.

 

I paid about 1500 for parts and labor to swap 3.73 to 4.30, best money I've spent on my truck. Installer got the gears and master rebuild kit from Randy's.

 

Some info on your truck would be most helpful...

 

If he's set on nitro 4.30s it's a 2011&up. If you can find a good rate on getting them installed $1500 isn't far fetched. I did my own install, front locker and gears for under $1200. I have a few on the newer trucks done both gas and diesel. Also have the knuckle seals replaced don't try to reuse. Get them on Amazon, cheapest place to go for them.

 

2016 f250 XLT CC SB 4x4... Has a 5 star perf/tow tune...I pull a 8000 pound TT and am wanting to move from the stock 275/70 18 tires to 295/70 tires (34")

I only have 3700 miles on the truck so it's not being traded in for a 2017.

 

Before you do anything call "Staticz2229' @ (641) 751-8060, this guy and his wife advertize in several big car mags and sell on ebay. They have new Dana R&P and almost new take out sets. He charges way less than Randy's and ALL dealers. Very much worth a phone call...........Dave

 

If I had to do it again I would have went with 4:56 instead of 4:30 but I have a 5.4 and not a 6.2. With that being said if you are going up in tire size I still would say go with 4:56..

 

For the 11&up 4.30 is the tallest gear you can get for the rear axle. I haven't seen anyone swap an older 10.25 gear in yet but can't say it's impossible. I don't have the down time to try. With only 3700 miles on that truck a decent shop will reuse your bearings and save you some money.

 

Good point on going deeper than 4.30 with the taller tires. I'm not too familiar with the 6.2 or your better trans but on my '05 EX (2V V-10 and 4R100 trans) I went from stock 3.73s to 4.88s to get back to an effective 4.30-ish ratio with my 35" tires. Our EX serves as our dedicated tow rig for our 11,000lb TT and the gear swap has been the single biggest performance increase I've done!
