Ford 9" Pinion Guard

Serious protection for your Ford 9" pinion and U-joint — built for abuse, not show.

This pinion guard is built from a combo of 3/8" and 1/2" steel to stand up to real-world hits without flinching. The mounting plate is cut from solid 1/2", while the guard itself is 3/8" — thick enough to shrug off years of hard trail use. It offers better bolt access than older designs, while still fully shielding the hardware and extending far enough to actually protect the U-joint — not just the yoke.

Designed to fit U-joints up to 1410 size, it bolts on solid and comes with all necessary hardware. Whether you're running rocks, mud, or anything in between, this guard helps keep your driveline intact. It's a simple upgrade that saves you from expensive repairs down the road.
