J.C. Whitney JC55010053 Quarter Panel Dog Leg Passenger Side OEM Replacement

The J.C. Whitney JC55010053 is a passenger side (right-hand) quarter panel dog leg OEM replacement designed to restore the structural integrity and appearance of your vehicle's lower body. The dog leg panel covers the area located directly in front of the rear tire and behind the rear door, where it meets the rocker panel — one of the most common areas to suffer from rust, road debris damage, and corrosion on these full-size GM trucks and SUVs.

Key Features:

• Passenger Side (RH) — direct right-hand side replacement
• OEM Replacement — engineered to match original factory dimensions and contours for a precise, gap-free fit
• Targets the most vulnerable rust-prone zone: the lower quarter panel dogleg area in front of the rear wheel
• Designed to be welded in place after cutting out the damaged or rusted original panel
• Primed finish ready for scuffing, priming, and topcoating with automotive-grade paint
• Manufactured from stamped steel for strength and durability comparable to OEM construction

The dogleg section is one of the first areas on these full-size GM platforms to show corrosion, especially in regions exposed to road salt and moisture. This direct-fit replacement panel allows body shops and experienced DIYers to restore the vehicle to a like-new appearance without full quarter panel replacement. For complete rust repair coverage, consider pairing this panel with the corresponding outer rocker panel.
