J.C. Whitney JC43010075 OEM Replacement Rear Rocker Panel for 1973-1991 Suburban

The J.C. Whitney JC43010075 is an OEM-replacement rear rocker panel designed for 1973–1991 Chevrolet/GMC Suburban applications. Rocker panels are a critical structural and cosmetic body component located along the lower edge of the vehicle between the front and rear wheel openings, and are among the most rust-prone areas on classic trucks and SUVs of this era.

This panel is engineered to match the original equipment profile, restoring the structural integrity and appearance of the lower body. The RH=LH designation means the right-hand and left-hand panels share the same stamping, simplifying the replacement process for both sides.

Key Features:

• OEM-style replacement rocker panel for accurate fit and finish
• Rear section panel — RH=LH (single panel fits both driver and passenger sides)
• Designed to match original contours and attachment points of factory panels
• Suitable for rust repair, collision repair, or restoration projects
• Compatible with 1973–1991 Chevrolet/GMC Suburban (4-door)
• Steel construction for strength and durability
• Supplied in bare/primed steel, ready for prep and paint

Whether you're tackling a full restoration or addressing rust damage on a classic Suburban, the J.C. Whitney JC43010075 rocker panel delivers an OE-matched replacement that ensures a proper fit with minimal modification required.
