J.C. Whitney JC43010064 OE-Style Rocker Panel Driver Side Crew Cab 1999-2006

The J.C. Whitney JC43010064 is an OE-style replacement rocker panel designed for the driver side (left hand) of 1999–2006 Chevrolet Silverado and GMC Sierra crew cab pickup trucks. Constructed from 2.0mm steel, this panel is engineered to restore the structural integrity and appearance of the lower body section between the front and rear wheel openings.

Key Features:

• OE-type replacement — matches original factory profile and contour for a precise fit
• 2.0mm steel construction — heavy-gauge material for strength and long-term durability
• Driver side (LH) — left-hand fitment for crew cab 4-door configuration
• Crew cab specific — designed to span the full length of the four-door rocker section
• Primeable surface — ready for prep, priming, and finish painting to match vehicle color
• Backed by J.C. Whitney's 1-year, unlimited-mileage warranty

Rocker panels are among the first body panels to show rust and corrosion damage due to constant exposure to road salt, moisture, debris, and the elements. This direct replacement panel from J.C. Whitney restores the lower body structure of your truck to a factory-correct appearance. Professional installation with welding is recommended for a proper, lasting repair.
