2012 Jeep Wrangler: Needs Proper Gearing
February 21, 2013
Given our Wrangler's huge tires there's no need to ever use sixth gear. At 70 mph in sixth the Pentastar V6 is turning over only about 1,850 revolutions per minute. And that's just not enough to pull even the slightest hill. Even a medium crosswind will trigger the need for a downshift. Fifth gear is only turning about 2,350 rpm at the same speed and that's a usable engine speed.
Lower axle ratios, of course, are the answer. These would get us a better crawl ratio, too. Lower gearing would save our clutch both on and off road. But it's in everyday driving that the benefits of proper gearing would pay the biggest dividends.
