Upgraded differential
I put bigger wheels on my 05 Durango and I notice that the truck is not as quick off the line. I'm thinking about changing the gear ratio to get it back. I'm doing some other modifications as well that will add horsepower. Cold air intake. Throttle body spacer, and American thunder catback exhaust. But I'm wondering what gear ratio I should be looking for right now it has the 3.55
