Timing Cover Seal 03-21 Hemi 5.7L

The Timing Cover Seal 03-21 Hemi 5.7L is a critical gasket component designed for Dodge, Chrysler, and Jeep models equipped with the legendary 5.7-liter Hemi engine. As a veteran mechanic, you know that timing cover seals are the first line of defense against oil leaks at the front of the engine block—a common failure point on high-mileage Hemis and vehicles subjected to aggressive driving or modifications. This OEM-specification seal maintains positive oil containment around the timing chain cover interface, preventing slow seeps that can compromise ignition timing sensors and accessory belt life.

Manufactured by MAHLE ORIGINAL/CLEVITE, this timing cover seal is engineered from premium elastomer compounds formulated to resist the thermal cycling and pressure cycles inherent to modern Hemi performance engines. The 6-inch outer diameter and 0.13-inch wall thickness are optimized to create a durable, compression-fit seal that accommodates both factory engine bay temperatures and the elevated heat output of supercharged or turbocharged builds. MAHLE's precision manufacturing ensures dimensional accuracy to OEM tolerances, meaning zero fitment issues or edge separation when properly installed on the timing cover housing.

This timing cover seal is the go-to replacement for any 2003–2021 Hemi 5.7L engine experiencing oil weeping at the front cover—whether you're maintaining a stock 370-horsepower truck, restoring a classic Challenger, or rebuilding an engine after performance modifications. Installation is straightforward during routine timing cover service or full engine tear-down; simply seat the seal into its groove and torque the cover fasteners per factory specifications. Buy this MAHLE seal for worry-free sealing integrity and avoid costly oil contamination of belts and sensors down the road.
