I am putting 35'' tires on my truck and im wondering if i should go to 4.1 gears. I dont know much about this but would i just need to get this?? http://www.ringpinion.com/ProductDet...px?ProdID=1433
or do i have to get something else with it.

 

For 35's, the general recommendation is 4.56 gears. Being as your truck is four wheel drive, you would also need to do the front...... The Dana 44 carrier (which is what your front axle is.) would require either a different carrier, or, thick gears to work. Your rear end is a 9.25. The gears you linked would not fit.

You will also need install kits with the gears. Carrier bearings, pinion bearings, crush sleeve, and assorted shims.

Don't go cheap on any of these parts. Cheap gears will whine at you. Cheap bearings will give you the opportunity to rebuild your rear end again.... after a failure.... which is never cheap. Yukon gears, Timbren (timken?) bearings.

Do it once. Do it right. Never worry about it again.

 

I second the 4.56's... I came up from 3.92's which is pretty close to 4.10's obviously, and I really dig them..

with your tranny and o/d, and increasing the diameter of the tire- your overall gearing will increase marginally.. down low though, you will love it..

 

On estimate how much will it cost for me to do the front and rear with 4.56? and everything need besides labor.

 

somewhere in the neighborhood of 500-600 dollars. That is for both gear sets, two master install kits, of good quality.

 

it's going to vary by region..

I bought my gears and master rebuild from moe's.. Motive's.. $600

I got a local garage to do the install @ $300 per axle.. I went through about five shops until I found one I was comfortable with.. the guy that said "yeah, we'll have to put them in and take them out several times to make sure we're getting the right pattern and have the right backlash" was the one who won my favor.. the other guys wouldn't comment too much on the job- which led me to believe they weren't really familiar with it and were pricing it by what the 'book' quoted..

point being- make sure and get someone who knows what they are doing to install them.. this is one job i personally wouldn't even consider doing myself.

total install cost $1200

 

is the Dana 44 a 8'' Ring and pinion set?
Would this be everything i need? Or will it not fit because its for a different year dodge but the same size rear.

I've been thinking about doing the same thing, right now I have 33" tires, but that may change in the distant future, so I was thinking about going from the stock 3.55 to 4.56, is that too much?

 

I think they changed axle manufacturers for the third gen trucks, so, chances are good, that it won't work. There are similar kits available for second gens though.

@muzz3256 Gear changes are not cheap..... So, if you ever plan to go to 35's, do the gear change once, and go with the 4.56s. With 33" tires, your rpms will be 2-300 higher, than they would with 35's. So, no major difference there. (and you will probably love the extra grunt you get by doing so......)

 

Third vote on the 4.56's. I was running 4.88 with 35 inchers on the Jeep, but that was more offroad than anything (although Im now at 6.17 with my 47's). 4.56 is better for a daily driver and 35's.

I have regeared dana 30, 35, 44, 60's, and GM 14FF. never once did i need a case spreader, just a good dial indicator with a magnetic base, torque wrench, and quite a bit of patience. make sure you do all your pinion depth, backlashing, and patterning BEFORE you install the crush sleeve. Like mentioned, be prepared to install everything in and out several times to get it right. I have always pulled the axle, but i can be done under the truck. just a real PITA on your back.

Randy's has been good to me for customer service, get the YUKON gears and master shim/bearing kit.
