Bigger tires without re-gearing leave your Jeep gutless and constantly hunting for the right gear. We correct that by re-gearing differentials and axles to ratios that match your tire size, transmission, and driving style. Whether that means 4.56s on a light JK or 4.88s/5.13s on a heavier JL on 37s, we walk through options during a re-gearing consultation so you understand the tradeoffs. Our gear ratio optimization process focuses on restoring usable torque, better throttle response, and reasonable RPMs at cruising speed. Done right, the Jeep feels stronger off the line, happier on grades, and less stressed everywhere.
