2010+ Camaro GM Performance 1LE 3.91 Gear Kit

This lower (higher numerically) ratio rear drive gear will increase effective rear wheel torque multiplication in 2010 – 2013 SS Camaros by 13% (over standard 3.45 ratio) in a manual transmission-equipped car, and 20% (over standard 3.27) in an automatic-equipped car. This gearset is the original equipment ratio found in the 1LE 2013 Camaro package.

NOTE: This change will affect the indicated vehicle speed. Recalibration is required for accurate speedometer reading.
