        Can this be used with 4.88 gears?

        • Thank you for your question! This locker would work in conjunction with 3.73 ratio's and numerically lower, like a 3.55, 3.21, or 3.07. I have listed a link to an LSD below that will work with a 3.92 gear ratio and higher. https://www.extremeterrain.com/auburn-gear-pro-series-jk-tj-yj-542082.html
