Matt I can appreciate what you said regarding "the majority of owners who will do this mod aren't concerned with a 200 RPM difference on the highway" I agree.
But... I do see an awful lot of threads on gas mileage (I Know we don't drive fuel efficient vehicles. Primarily why I got such a great deal 4 years ago) But to put it out there someone who has the 545RFE and sees 2000rpm @75mph with the effective higher gear ratio from their 32's is gonna crap themselves with the gas mileage at 2200-2500 rpm! I'm fortunate to live here in Colorado with plenty of wide open spaces between places so my fuel economy is a bit better than someone who is stop and go, speed up and slow down. But as they say Slow and Steady.
- Just trying to discuss..
What effect would an over geared axle drive ratio have on the (4 Low) Crawl Ratio. Would that be beneficial or negative to off road performance?
