        I'm happy to help, Chris! This Motive Gear Spider Gear Kit (Part No. C9.25BI) is designed to fit the rear differential of a 2005 Dodge Dakota SLT 4WD with a 9.25" (12 bolt) axle. Your front axle should be an 8". I do not see a spider gear kit available on AdvanceAutoParts.com for your vehicle. I suggest checking with your local store for availability of spider gears for your truck.

        The pinion pin size is 3/4" across the shaft and should be 1" long approximately. It is a spider gear open differential unit and is an ideal fit for your 2003 Dodge Dakota.

    • Q:

      How do I find the gear ratio on the rear end of a 1997 Dodge Ram 1500 pickup
      Asked on 4/24/2010 by Rob from Fort Benning, GA

      2 answers



        The gear ratio is ring gear number count devided by pinion gear number count.

        Answered on 4/26/2010 by Kevin from AAP
      • A:

        There is a metal tag bolted to the outside differential cover. There are two rows of numbers. Look at the lower row. There will be a number that looks like this 3 54 610422-1. The 3 54 portion is the gear ratio if the unit has not been altered. The rest of the number is the Bill Of Material number that can reveal all the details of what parts were used during the original manufacture of the axle.
