FenFabrication Diffy Stiffy Brace (2020-2026 Ford Explorer)
Added Differential Support for High-Load Explorer Builds
The FenFabrication Diffy Stiffy Brace is engineered to address a known weak point on 2020-2026 Ford Explorer models where the rear differential is mounted to the subframe using a single mounting bolt. While adequate for normal driving, aggressive launches and hard shifts can place excessive strain on this single stud - sometimes leading to premature wear or failure.
This brace adds critical supplemental support to the differential assembly, reducing stress on both the mounting bolt and the differential cover. It is also compatible with Explorer differentials that use two mounting bolts, providing additional reinforcement even in those configurations.
With a simple, bolt-on installation, the Diffy Stiffy Brace helps stabilize the drivetrain under load, aiding in the reduction of wheel hop and driveline slop. The result is a more planted feel during acceleration and improved durability for performance-driven Explorer builds.

FAQs
Why do some Explorer differentials need additional support?
Some 2020+ Explorer ST models rely on a single mounting bolt for the rear differential. Under hard launches and sporty driving, this can place excessive strain on the mount, which the Diffy Stiffy Brace helps alleviate.
Will this brace work on Explorers with two differential bolts?
Yes. Even on two-bolt setups, the brace provides additional reinforcement and improves drivetrain stability under load.
