Hi I have a 2008 Jeep wrangler unlimited with 3:21 that I'm installing 4:10 into is this the right locker or do I need one for 3:92 or higher

Asked by Mike from Enfield CT on

Hi Mike, This Detroit Locker Dana 44 30 Spline 3.73 Down Rear TrueTrac is the correct one for your JK Wrangler using 4:10 gears since your model uses a thick cut gear you need these 3:73 and down version. Thank you for your inquiry.
