J.C. Whitney JC55010054 Front Lower Quarter Panel Dog Leg Driver Side Primed Steel

The J.C. Whitney JC55010054 is a front lower quarter panel replacement designed for the driver side (left-hand) of compatible Chevrolet Avalanche and Cadillac Escalade ESV full-size trucks and SUVs. This dog leg-style panel targets the structurally vulnerable lower front quarter section — a common rust and collision damage zone — restoring factory body lines without replacing the full quarter.

Key Features:

• Steel construction — stamped from heavy-gauge steel meeting or exceeding OEM panel thickness
• Primed finish — factory-applied primer ready for bodywork and paint
• Dog leg design — covers the lower front quarter section at the rocker/door junction area
• OEM-matched geometry — engineered to match original body contours for precise panel gap alignment
• Driver side (LH) — left-hand fitment; verify side before ordering
• Weld-in installation — old panel must be cut out and new panel welded in place
• J.C. Whitney 1-year unlimited-mileage warranty included

This quarter panel section is an effective, cost-saving alternative to sourcing a full OEM panel assembly. Professional installation is recommended, as this is a weld-in replacement panel requiring cutting and welding equipment.
