Description
A 4.11 gear ratio transforms your GM 12-bolt into a hard-accelerating, track-focused differential that demands respect on the strip and street. Whether you’re launching from a standstill or pulling through the mid-range, this aggressive ratio cuts parasitic losses and delivers the kind of response that separates competitive builds from the rest. If you’re serious about quarter-mile times or spirited driving, this is the upgrade your drivetrain has been waiting for.
