Show original supplier description

The Ford F81A-5598-DB is an original equipment (OEM) rear axle leaf spring spacer block for Ford Super Duty trucks. This component serves as a spacer between the leaf springs and the axle, incorporating a bump stop perch and measuring 3.75 inches. This specific part is a used, genuine Ford component in good condition, showing only light wear consistent with its prior use. It was salvaged from a 2002 Ford F-350 Lariat equipped with the 7.3L Powerstroke diesel engine, 4R100 automatic transmission, and 4WD drivetrain. The approximate fitment range for this spacer block is from 1999 to 2007 for Ford F-250 and F-350 trucks. While this part number (F81A-5598-DB) is listed, it's important to note that it has supersession numbers including F81Z-5598-DA, indicating potential cross-compatibility. Always verify fitment using the part number prior to purchase, as actual fitment may vary. As a used part removed from a salvage vehicle, it is sold AS-IS with no warranty. Buyers are responsible for verifying compatibility and fitment for their specific application before purchasing. Normal wear and tear associated with used items is to be expected.
