Description

Product Overview

The Fel-Pro Drive Axle Shaft Flange Gasket is a precision‑engineered component designed to meet the demanding requirements of heavy‑duty pickup trucks. Manufactured by DRiV Incorporated under the reputable Fel-Pro brand, this gasket features a fully machined exterior that provides a uniform surface for optimal contact with mating flanges. The proprietary sealing compound is formulated to conform to irregularities, ensuring a leak‑free seal even on imperfect surfaces. With a part number of 55487, the gasket weighs just 0.739 ounces and fits within a compact package measuring 9.88 x 7.28 x 0.28 inches, making storage and handling straightforward. Engineered for the 2011‑2022 Chevrolet Silverado 2500 HD, Silverado 3500 HD, GMC Sierra 2500 HD, and Sierra 3500 HD, it addresses the specific torque and pressure specifications of these models. The design incorporates Fel-Pro’s exclusive sealing technologies, which combine high‑temperature resistance with chemical stability, delivering long‑term durability in harsh under‑hood environments.

Usage

This gasket is intended for use during axle repair or replacement procedures on the specified Chevrolet and GMC trucks. It is ideal for both professional automotive technicians and skilled DIY enthusiasts who need a reliable seal when reassembling the drive axle shaft flange. The gasket performs best when installed on clean, dry mating surfaces, and it tolerates a wide range of operating temperatures typical of heavy‑load hauling, off‑road excursions, and daily commuting. Because the sealing material adapts to surface imperfections, it reduces the risk of coolant or oil leaks that can lead to costly downtime. The product’s lightweight nature does not compromise its strength; it maintains structural integrity under the high‑torque loads experienced during towing or payload operations. Whether you are performing a routine maintenance service or addressing a critical axle failure, this gasket provides the confidence of a secure seal.
