Crawl slow, run lean
Can I-Shift with crawler gears really help boost your fuel economy? Sure. Because previously, you often had to be willing to sacrifice fuel economy for startability. But thanks to the crawler gears, we can now specify your truck with a faster rear axle ratio, allowing you to stay on cruising speed at much lower revs when you’re driving on decent roads. This lowers your fuel consumption by up to a couple of percent.
