Gears?
So i have 3.55's now, but switching from the stock 235 to 285 I did notice a power difference in take offs. And towing 8000 lbs can put my egts in the red really quick. Now I am getting a bigger trailer for moving dirt and gravel off job sites and will easily be 12- 14k. I can make the 3.55's work on the highway but grades and getting on and off the job sites is hard on the tranny. So the cheapest fix I can see is a re-gear. I drive around 100 miles daily so I need the medium of towing some and MPG mostly.
I was thinking 3.73's over the 4.10'
What do you guys think?
How hard is it to change gears? And looking around I see sets around 180 but then master install sets for around 350. WHat do I need?
Thanks for your input

I have 4.10s and have 33's on it right now. It doesnt like to go much over 70 though. I have only had it a couple of months but it pulls my 27' trailer with two 4 wheelers in the bed just fine. I get 16mpg on the freeway.

I had 4.10's and switched to 3.55's. I had 215/85/16 and now I've got 37/12.50/16.5's. I like it very much better this way. I've never had trouble pulling anything I've hooked up to, but then I don't haul like some of the guys on here.

After re-reading your post, I think you may want to regear. Pulling in soft soil, hills, etc, is not something I have to deal with very often. Also, mine's a 5speed, so the overall gearing is a little shorter on mine. Yeah, on second thought, re-gear, or stay with the smaller tires.

The 4.10's would be awsome but I don't like the 16 highway MPG. I get around 20 highway average 18 mixed driving around DC. I just didn't want to get the 3.73's and wish I had more, but then it might be enough. If I didn't like the 4.10's I could move up to 35" tires, but then i would need the 6" lift and ...well those off you who are married know where i am going with this.

Yup! And loving it! If I had an auto, or pulled really heavy loads I'd probably have stayed with the 4.10's or gone with smaller tires.

Did you change the gears yourself? Is it pretty straight forward--or best left to someone whose done it? THat is the bigest question I have$$$$ I don't want to have to pay someone 500-700 in labor to change them out.

I had someone else do it. Swapping is easy. Setting the backspacing is where it gets a little dicey. That's the first work I've ever paid anyone to do other than body work.... If I could get it done for $150, it wouldn't even be a question.

Well actually he would need an underdrive unit. USgear sells them. not cheap, but it shifts with the push of a button, and you can shift under full load at any speed. they are rated for 35,000 lbs and the unit will reduce your gears by 20%, or increase by 20% if you get an overdrive unit.
Edit: this means that when disengaged you'll still have 3.55, but when engaged you'll have 3.55 x 1.2 = 4.26.
