When fitting the 1551-26, confirm the yoke ear bore accepts ISR (inside snap ring) retention and that the bore diameter matches 1.043" cap diameter. ISR snap ring grooves are cut into the inside of the yoke ear bore — the snap rings must seat fully in their grooves before the joint is considered secure. The 1.988" width must match the span between the yoke ears on the Kia or Mazda driveshaft.
The 1551-26 cross-references to Spicer 5-3245-1X, which can be used to verify fitment against OEM Spicer catalog data for the listed Kia and Mazda applications. Kia/Mazda series cap dimensions (1.043" x 1.988") differ from standard SAE series — do not use a 1310 or similar series U-joint as a substitute. Verify 1.043" cap diameter against the yoke ear bore for the specific vehicle year and model before ordering.
