J.C. Whitney JF43010030 OEM Replacement Rocker Panel Left Side 1.2mm Steel

The J.C. Whitney JF43010030 is an OEM-style replacement outer rocker panel designed for the driver (left) side of Ford F-Series full-size pickup trucks. Engineered to restore the structural integrity and appearance of rust-damaged or impact-damaged rocker panels, this part is built to match original factory dimensions and contours.

Rocker panels sit low on the vehicle and are constantly exposed to road debris, moisture, and salt — making them among the first body panels to show rust and wear. This direct replacement panel is manufactured to 1.2mm steel thickness, providing durable, long-lasting coverage without pre-drilled holes, giving installers flexibility during fitment.

Key Features:

• OEM-style replacement — matches factory profile for proper fit and finish
• 1.2mm steel construction — sturdy gauge for structural durability
• No pre-drilled holes — allows for flexible, custom installation
• Left (driver) side fitment
• Compatible with Regular Cab and Extended Cab configurations
• Includes fitment for the 2004 F-150 Heritage edition
• Primeable surface ready for paint to match your vehicle

This panel is backed by J.C. Whitney's commitment to quality OE replacement parts. Whether you're restoring a daily driver or preserving a work truck, the JF43010030 delivers the precise fit needed for a professional repair.
