Suggestions of Mods.

[boss13]

Sorry to hack the tread but I'm confused. if I understand correctly numerically higher gears doesn't necessarily kill your gas mileage? I have 305/45/22 so I guess that's about a 30.5 in tire - stock 3:73 5.3/60e I'm turning 19-2k @ 70mph and avg 17.8 mpg should I consider changing gear ratios to obtain better mpgs?

Getting lower in number or higher in ratio used to be something people thought helped MPG but if you make the engine work too hard to haul the weight the MPG will suffer greatly. When I started in the dealers in the early 90's people bought 5.0's then realized the 5.7 got better mileage....

any recommendations on my set up?

I had the best luck with some performance mods for my four wheel drive the cold air kit exhaust and programmer got me just over 19 mpg on the high way with 3.73s and 33 inch all terrains

I have the k&n and exhaust. The only thing I 'm missing is the nelson tune!-soon to come.

Gears are the way to go for you at this point. It all about leverage.

I am in the same boat as you right now,
5.3 with 3.42 on 33's, not exactaly a tow pig but as soon as my kid is born and the wifey gives me the thumbs up my trucks getting 4.30's and a trutrac

35's 6.0l and 4.10 heres pulling upwards of 10k on a monthly basis. Not exactly great on gas, could probably stand to go to 4.56 since at my traveling speed is right around a shift point and it tends to work a lil harder than it should if i dont pay attention.

i decided to swap my gears to 4.10s or maybe a little more since i might start pulling a 29' boat, might go with 4.56s, but i am also going to put air bags on the rear axle to level the truck, any suggestions where to get the gears and bags?

I got my helper bags from summit. Get the ones with the air compressor and switch that mounts inside the cab. I can hook up to the trailer by letting all the air out of the bags, back up to the trailer and fill the bags and up it goes. I only wind up the jack to keep it from hitting the road.
