I just ordered this product from 4WD and want to ensure it will fit my 2009 Wrangler Sahara Unlimited Dana 44, 30 spline rear differential. I'm installing 5.13 gears with it. Thanks.

Gene, Unfortunately this Detroit Locker Dana 44 30 Spline 3.92 UP Rear TrueTrac is incorrect for your application. You will need a 3.73 and down carrier. I will put a link below for the correct one. Please let us know if you have any other questions. Thanks!
