Product Details

The Motive Gear D8BZ4230B is a replacement differential pinion gear thrust washer engineered to meet or exceed original equipment manufacturer (OEM) specifications. This precision-manufactured thrust washer is a critical internal differential component that controls axial play on the differential pinion gears, ensuring proper gear mesh, smooth rotation, and long-term drivetrain integrity.

Manufactured by Motive Gear — a division of Midwest Truck and Auto Parts and an industry leader in drivetrain components for over 65 years — this thrust washer is built to the same exacting tolerances as the OEM part it replaces. It is a direct replacement for Ford OEM part number D8BZ-4230-B.

Key Features:

  • Engineered to meet or exceed OEM fit, form, and function
  • Precision-manufactured for proper axial load control within the differential assembly
  • High-quality steel construction for durability under normal and demanding driving conditions
  • Direct OEM replacement — cross-references Ford part number D8BZ-4230-B
  • Manufactured under strict quality control standards for consistent tolerances
  • Backed by Motive Gear's 1-year / 50,000-mile limited warranty

The right price for the right part. Timely response to placement of order. Very interested in customer feedback!<br><br>Brian C.

Quick and easy

Easy to shop n order

Site was easy to use, customer services was very pleasant helpful when I needed to information on my order status. Will do business with them again.

Not sure why 1 item qualified for free shipping and the other didn't. They were both in stock. One was right side and one was left side. The price dropped after I placed my order but thanks to the buySAFE I would submit for the difference.

It was easy...

User friendly system

Love the pay with Amazon feature. Unbelievably fast shipping, great pricing on product. Excellent communication through the process. I'll be back!

Fair price no hassales

Good so far

Good price, fast delivery, just charge a little bit high on the shipping cost. Will refer friends to shop here.

Easy enough until it came to payment. "Check out with Amazon, it'll be faster." It wasn't.

good shopping experience
