Good Job!

Im jelous I just found out I have 3:55 gears and I thought I had 3:73s
Oh well doesnt change anything anyway, I still need new gears!

 

what are they going to check for on monday?

 

Lol 3.55 to 4.56 will be major difference, you'll love it

I'm averaged right at 15 right now so no loss in mpg average

Monday they're going to fix the leak and top me off with fluid again for whatever drops out between now and then

 

Fixed the leak and runs perfect

2-1 shift at WOT I can't keep traction!

Im currently running 91 octane and take the mods in my sig into consideration when reading the above comment AND I have 4 35x12.50x18 mud grapplers in the bed so theres quite a bit of weight that could be shed for more improvement

Last tank was 14.79 with 70/30 city/highway

 

My truck doesnt feel that bad right now, but my 35s only measure 33",
Im thinking maybe I should only go with 4:10s! guess Ill have to wait till I get 37"s to see how bad it really is! Waiting: story of my life!

 

If your going to 37s I definitely recommend 4.88s

I feel like the 4.56s aren't adequate enough for me, but again there's probably an extra 200-300lbs in the bed of the truck. I think I'd only be happy with a supercharger

 

Thanks Bro! Ill consider it!

 

What do you think would be the better choice for the price, considering you have both now- a tuner or 4.56's. I currently have 3.55's and am getting 9.6mpg .....ya its bad. So what would be better, spend the extra money and get some mpg's back or just go with the tuner because I need to do something to get the power back, I only have a 4.6 ....?

 

New gears should always be your first consideration after installing bigger tires. I have both and definitively felt better overall ''relief'' when installing the gears. The truck just runs a lot smoother with them.

 

I feel safer with the gears about my transmission lasting

HOWEVER,

Do keep in mind you'll have to find a way to tell your truck that you're running 4.56 gears. I would get the tuner and take it easy on the truck, and get the gears as soon as possible

And ouch 9mpg, my average of 15 hurts

 

Post sum vids on Youtube! Your be a "FIRST" lol. But glad to hear you had the new gears installed. Also I was just curious would u say the headers were worth the money other than for the sound.

 

awesome man! how are your rpms at 60?

 

Ya I would love to get the gears first too,......I just gotta find the nearest shop thats not $1000 an axle

 

Go to diffsonly.com ask Wayne to give you a quote for what you need. He does the best prices for Yukon stuff... and you should be able to find a shop that does it for about 250-300$ per axle for installation.

 

Id need a better camera, something I could setup without holding.

rpms at 60 im guessing are at 1800-900 which was what it used to be with my 3.73 at 75mph

At 75 im running around 2200rpm

Headers were well worth it Not anything greatly noticeable but I felt it and the sound is sex!

Yeah thousand an axle is ridiculous! My rears with parts were somewhere around $670

Agreed with wayne, definitely great prices and best quote I found anywhere
