How to find the right part

  • Match the part number. The surest fit is the Spicer part number stamped on or listed for your old part. Search it in the store search bar.
  • Know your axle. Check the axle tag or build sheet to confirm your Dana axle model and whether it is front or rear.
  • Check the fitment on each listing. Each product page lists the part number and known applications. Compare these before you order.
  • Not sure? Email sales@platinumperformanceparts.com with your vehicle year, model and axle before you order.
