The J.C. Whitney SET-JF58140027 is an OEM-style replacement cab corner panel set for Ford F-250 and F-350 Super Duty trucks. Sold as a complete pair — both driver side (LH) and passenger side (RH) — these panels are engineered to restore the lower rear cab corners that are prone to rust, corrosion, and impact damage over time.

Constructed from 1.2mm steel, these panels offer a durable, factory-matched thickness that ensures structural integrity and a proper fit during installation. The extended cab corner design includes the extension section, making it compatible with both Standard Cab and Crew Cab configurations.

Key Features:

• Set includes both driver side (LH) and passenger side (RH) cab corner panels
• 1.2mm steel construction for OEM-equivalent strength and durability
• Designed for Standard Cab and Crew Cab body styles with extension
• OEM replacement style for direct, precise fitment

These cab corner repair panels are designed to be welded in place, delivering a clean, professional-quality finish that blends seamlessly with the existing body lines of the truck.
