It might seem silly to talk about gears in a power article, but it’s true. While the 2.5L isn’t built for high revs, it will spin in the 3,000 RPM range all day long. If you are running 30-inch tires, your 4.10s will eke you by. If you have 31s and live in Kansas or somewhere else flat, you’ll manage. Once you go bigger, don’t even think about pussy-footing around gears. We ran 5.13s with 33s and it was about as good as the little engine can get. If you have the 2.4L engine, it will rev even higher. Don’t be afraid to gear it down. Good for 5-10 hp on the dyno and will save countless gray hairs in real life.
