Product Description

The SPC Performance 35104 Replacement Ball Joint Kit is engineered to restore and upgrade the front upper control arm ball joints on your Ford F-150 or Expedition. Designed as a direct replacement for SPC's upper control arm assemblies (parts 25675/25680), these ball joints offer serious durability and alignment flexibility for performance or lifted applications.

With a sealed-boot, high-strength forging, oversized articulation and corrosion-resistant finish, this kit delivers premium performance, reduced maintenance and improved tuning capability. Whether you're running stock suspension, lowering or lifting your truck, or prepping for aggressive alignment settings, the 35104 kit is built to handle the job.

Installation is straightforward for users familiar with front-suspension removal on 2004-20 Ford F-150 (2WD/4WD) and 2007-17 Expedition. While fitment is confirmed up to 2020 for F-150 and 2017 for Expedition, coverage for 2021 and newer Ford platforms is unconfirmed at time of listing.
