Product Description

The USA Standard Gear ZA F880033 is a direct-fit replacement rear axle shaft for the passenger side of 1997-2004 Ford F-150 trucks equipped with the Ford 8.8" rear differential. Measuring 31-7/8" in length with 31 splines and a 1.620" bearing journal, this shaft is dimensionally matched to the OEM specification for a straightforward, no-hassle installation using factory bearings, seals, and retainer hardware.

Covering a wide range of F-150 trims from base XL and XLT through performance variants like the Lightning and Harley-Davidson Edition, as well as the Expedition and Lincoln Navigator sharing the same 8.8" axle platform, this shaft is a reliable choice for restoring drivetrain function after wear, damage, or breakage. Always confirm your vehicle is equipped with the 8.8" rear axle - higher-output and heavier-duty models in this generation may use the larger Ford 9.75" axle, which requires a different shaft.
