I was wondering anyone running 4.7 gears and 4.10's? I know it sounds stupid but im not ready to re-gear my diff's but i want a little more for the 33's. Just wanting to get some opinions. How crappy is 4 high with 4.7's is my main question because I use 4H a lot. thanks

 

4H will be the same regardless of that low range gear set you use. 4H is 1:1 (directly coupled input to output), it is 4L that changes.

 

Yup. Zero change in 4 hi. You'll be the same as you were before. You'll like the low range though. Much nicer on obstacles. Only down side is the times when you are "in between" obstacles, but the trail is too rough for high range. Then you end up winding out the motor to keep up with the group. Its not awful, but for me, it got old after awhile. So I went to a dual set up.

 

thats some good info right there. ive been wanting to go to 4.7 but not sure yet

 

I thought duals but then i have to get a new drive shaft. Do you think 2 stock transfers might be better then 4.7's. I got $$$$ for one or the other but not both. Also i ll probably get flamed but my goal is to keep this vehicle IFS DD/Trail rig so if i get a doubler don't i also need to get a horse-collar and skids etc.etc.etc.? all this adds more $$$ to the situation.

 

With 2 stock cases, 2.28 * 2.28 = 5.20:1 so it is lower in low low range that a 4.7 gear set and you get a few other advantages, stock (2.28:1) low range and you also get 2L for free, since you can shift the front case into low range with the rear case in 2WD and 15 forward speeds instead of 10.

 

Dual stock cases with everything including the second case, dual transfercase crossmember, driveshafts (with making your own front square shaft) and random other odds and ends is gunna run you around $900 depending on the deals you find. I would definitely rather have duals with stock cases than a single 4.7, which is why I went the dual route. More options.

And what do you mean horse collar? Oh and mines a DD as well

 

Being thrifty like I am it only costed me the price of the adapter for the dual setup. ~$350. Built both my front and rear driveshafts out of spares I already had. I'm a packrat when it comes to yota parts. I notched my stock crossmember and threw a beefy piece of pipe in there. 6" dia, 1/4" wall, about 4 inches long and then cut it in 1/2. Can't run the full circle because the tranny and mount get in the way. Been rocking it for a while already but it's become temporary permanent till I can build my own crossmember/skidplate. Even built my own twin stick setup for the rear case. Went this route because I knew it would be cheaper than buying gears for both axles. But if u have to buy the driveshafts and crossmember, axle gearing may be cheaper and with that it would be much better on the street amd ur truck would like u more.

 

4.7s is going to be cheaper than duals.

4crawler makes good points to the advantages of duals, but you will need to either fab your own driveshafts or get them made, and you can use the stock cross member too. I did not have any issues with the horse collar when I went duals.

So, if you go bare minimum on duals, but aren't fabbing your own drivelines:

adapter - 350
second case- 50-100
drivelines- 200 ish, maybe more, maybe less

So, you are looking at around 600-700 bucks, depending on costs.

Its a bit more than the 4.7s.
