E39 M5 Aluminum Skid Plate / Undertray

The factory plastic undertray on the E39 M5 becomes brittle with age, making it prone to cracking and breaking, especially on lowered or hard-driven cars. Replacing it with a new OEM unit costs approximately $600, only to end up with the same aging-prone plastic design.

Our aluminum undertray offers a stronger, more durable alternative without compromising factory functionality. Unlike other aftermarket options, ours is the only aluminum undertray that retains the OEM-style cooling ducts, preserving the factory airflow and cooling design while providing the durability of aluminum.

Features

• Same cooling ducts as OEM: the only aftermarket undertray that keeps the factory duct layout.
  
• Aluminum construction: stronger and more heat resistant than the OEM plastic.
  
• Better ground clearance: slimmer than the OEM tray, so there's less to scrape.
• Black powder coat: protects against corrosion and keeps a clean OEM+ look under the car.
• Direct bolt-on: no trimming or drilling.
• Hardware included.
