4.10 gears - real improvement?
I have read a number of posts about gear changes ... 3.55 to 4.10 or 4.56 and how the 3.55 is a "real dog" gearset. I don't argue about the 3.55 being a dog.
I want to make the change but the affect on MPG is my concern. I run probably 60-70% city type (under 50mph) driving. I tow once or twice a year at the moment but haul truckloads of contstruction and landscape materials quite often.
My goal for my buildup has always been tow/haul related but with a decent highway setup.
Often stated in threads about gear changes is the "it may even help your mpg for city/highway" comment based upon the increase in rpm range associated with the lower gears.
My point is --- almost always I read "IT MAY" but rarely have I seen "IT DID". No offense to those who suppose a change should occur but:
How many actual gear changers on here noticed a better (or no change) mpg by swapping out their 3.55's? Doesn't matter if you went to 3.92, 4.10 or 4.56. What are the "REAL" mpg affects of your gear change?
