Detailed Description

This Dorman drive shaft, part number 986-938, is built for rear driveline service on the Ford F-150 and matches the 2018-2020 model years listed in the fitment data.

Confirm the vehicle’s driveline configuration and phase orientation during replacement to maintain proper balance and fitment.
