447-1574L Rear Left 31-Spline Steel Drive Axle Shaft – New OE-Spec Fit for 1987-1996 Ford F-150 & Bronco

Keep your 1987-1996 Ford F-150 or Bronco moving with a US Powertrain rear left drive axle shaft built to original equipment specifications. Machined from solid steel for maximum strength, this 31-spline shaft measures 33 3/16 inches to deliver a precise, direct-fit replacement for the rear driveline. A rust-resistant coating helps the shaft withstand road salt, moisture, and everyday wear, extending service life in demanding conditions. US Powertrain engineers new axle shafts rather than remanufacturing worn cores, so you get full, unworn strength from the first mile. Whether you're restoring a classic Bronco or keeping a work-ready F-150 on the road, this shaft is manufactured in the USA and backed by a 1-year parts-only warranty for added confidence. Note that wheel bearing, axle seal, and axle nut are sold separately and should be inspected or replaced during installation for best results.
