Description
Product Overview
The Dorman 926-880 axle shaft flange gasket is engineered as a precise, bolt‑for‑bolt replacement for the original equipment gasket. Constructed from a high‑strength, oil‑resistant composite, the gasket offers a leak‑free seal that endures the heat and pressure of daily driving. Measuring 0.09 x 6 x 6 inches and weighing just 1.28 ounces, it is lightweight yet robust, and it arrives ready to paint if a custom color match is required. The part carries OEM numbers 4384186, E0TZ1001A, and F3UZ1001A, guaranteeing compatibility with a wide range of vehicle makes and models.
Usage
Designed for both professional mechanics and DIY owners, this gasket is installed whenever the axle flange is opened for service—such as during bearing replacement, differential work, or axle shaft repairs. Its durable construction tolerates the high‑temperature environment of the axle housing, making it suitable for routine maintenance, heavy‑duty applications, and performance upgrades. Ensure a proper fit by entering your vehicle details in the garage tool; a confirmed fit indicator will appear, confirming compatibility before purchase.
