Aluminum differential covers

Adds a custom appearance while reducing temperatures

  • NOTE1: For Chevrolet differentials only.

Add a custom differential cover to your vehicle for an outstanding nostalgic upgrade. Lightweight and durable aluminum dissipates heat efficiently and quickly for reduced temperatures. A thick mounting flange increases strength and durability, while a magnetic drain plug allows for easy oil changes. Covers are available in as-cast, black powder coat, or polished finish, and mounting hardware included in each box.
