        Hello. I know I have a Dana 35 in the rear. But how do I know Spline Number and Gear Ratio? I understand I need those to order the correct product. Thanks.

        • Axle spline can be checked by counting the teeth on the axle itself, and gear ratio can be checked by counting the amount of driveshaft revolutions vs tire revolutions. Additionally if everything is stock, a dealer can check these based on the VIN.

            Alburn Locker

            Got my locker 3 weeks late! Install was tough but done right. If your not a Mechanic than have a off road shop install. I like a E-Locker because there in NO Complessor failuers and or the air line failures in the frozen mud. Locks right up and quiet. Very strong, works well... A few hundred less than a arb or compressor type. Works great!
