J.C. Whitney JD43010012 OEM Replacement Rocker Panel – Driver Side, Extended Cab, 1.2mm Steel

The J.C. Whitney JD43010012 is a driver-side (left-hand) OEM-style replacement outer rocker panel engineered for Dodge full-size pickup trucks with an extended cab configuration, covering model years 2009 through 2016. This panel is stamped from 1.2mm heavy-gauge steel, delivering thickness and rigidity on par with the original factory panel it replaces.

Rocker panels are located along the lower sides of the vehicle body, between the front and rear wheel openings, and are among the most rust-prone areas on any pickup truck due to constant exposure to road debris, moisture, road salt, and corrosive chemicals. A damaged or rusted rocker panel should be replaced promptly to maintain structural integrity and prevent further body deterioration.

Key Features:

• OEM-style fitment – engineered to match the original panel's contour and dimensions for a precise, factory-correct installation
• 1.2mm stamped steel construction – heavy-gauge material provides long-lasting durability and resistance to impact and flex
• Driver side (left-hand/LH) – designed specifically for the left side of the vehicle
• Extended cab application – sized and contoured for extended cab body style
• Primeable and paintable – bare steel finish accepts primer and paint for a seamless color-matched repair
• Direct replacement – restores OEM appearance and helps protect the vehicle's structural lower body

This rocker panel is designed as a weld-in replacement, requiring the damaged original panel to be cut out and the new panel welded in its place for a secure, factory-quality repair. Professional installation is recommended for best results.
