4.11 gear question
 

What rpm's are you turning in 6th gear at highway cruising speeds with 4.11's and also did you notice a decrease in gas mileage??

there are ratio calculators out there, try searching, i thought i had them bookmarked but i guess not

With a 26" tall tire(stock sized) ~2700 RPM.

He has a manual, not an auto. It tames it to like 2k rpm at 65-70 mph in 6th. Daskinnyguy just put 4.11s in and went from averaging 30 to like 27 mpg highway

to get the Rpm's go drive on the highway and use simple algebra, you have three known varibles and you want the 4th

With a 25.6" tire, 4.11 gears, 6th gear.....74mph @ 2,000rpm
