35" tires/ 3.55/ un tuned/ un regeared. i wouldnt do it. that would drop your gearing to 3.08 or so ( mathematically). i have 3.73's and am only going to 275/70/18 to maintain 3.60+ gearing. even going to 295/70/18 would bring my 3.73's down to 3.47, for me thats to low of gearing.
Def reading the signatures. Looking for anyone with 3:55's to see if dog from putting bigger 34-35" tires.
34.25s (295/70r18s) with SCT4 87 power/towing tune and 3.55 gears. Will break loose off line and power to spare. Putting true 35s and 18x9 Hostages on this weekend.
I will, by the way, eventually regear to 4.10s probably, but not soon.
Again, 3:55s, 18x9/1mm offset Fuel Hostages, Treadwright 35x12.5r18s, SCTx4 5* 87octane power/tow custom tune. Just got them mounted today, trimmed the front wheel wells and drove the 50 minutes to work. Nice ride, dropped 1 mpg (could have been because I was playing some) RPMs at 65 stayed the same (1500 - GPS speed). No feeling in power change and tranny temp remained the same (195). Love them so far with 50 miles on them.
You guys think a 4" lift and the 35" tires that would go with it are going to be a dog on a 3:55 geared truck?
Never thought I would get out of IL-is-stan but the house is for sale and the wife has a new job. We're moving to Athens, OH and I will be living in the hills.
Can't win, if I had a crystal ball the 3:73's would have been in this rig.
That is the setup I'm running (see sig). With my tune I don't notice any power loss. I was playing with it when i got off work last night and today at work had 3 of the guys ask me what work I had done to it and didn't believe me when I told them only a tune. All I have done to it is a tune.
