ECOTRIC Cab Corner Replacement Panels for 1999–2007 Silverado Sierra Crew Cab — Pair, Heavy‑Duty Steel

ECOTRIC cab corners are a pair of heavy‑duty, weld‑on steel replacements designed to restore and protect the rear cab corner panels on 1999–2007 Silverado and Sierra crew cab trucks.

If your Chevy Silverado or GMC Sierra crew cab shows rusted or damaged rear cab corners, these ECOTRIC replacement panels offer a direct-replacement shape and heavy steel construction to return structural appearance and corrosion resistance. Sold as a left and right pair in black finish, they fit a wide range of Silverado and Sierra 1500/2500/3500 models plus some Suburban years, and are manufactured to quality control standards for a durable repair option.

Which model years and cab types are these cab corners compatible with?

These cab corners were specifically made for full four‑door (crew cab) Chevy and GMC trucks from the late 1990s through 2007. They do not fit standard or single‑cab bodies and may require modification for a few specialty variants.

• Fits Chevy Silverado 1500 (2004–2007) and 2500/2500HD/3500 (1999–2007)
• Fits GMC Sierra 1500/2500/2500HD/3500 (1999–2007)
• Also fits Chevy Suburban model years 1999–2006
• Crew cab (full four‑door) only; Avalanche models may need adjustments

How durable are these replacement corners and what material are they made from?

ECOTRIC cab corners are fabricated from high‑quality steel and shipped in a black finish to resist everyday wear. The heavy‑duty steel construction provides a robust mounting surface and long‑term performance when correctly welded into place.

• Constructed from thick, high‑quality steel for strength
• Black finish for basic corrosion resistance and paint readiness
• Intended for weld‑on installation for a permanent repair
• Packaged as a matched left and right pair for consistent fit

What is involved with installation and will I need extra parts or modifications?

These cab corners are designed for weld‑on replacement and assume access to standard body repair tools and welding capability. Some trimming or minor adjustment may be required on specific models (notably Avalanche variants) to achieve a precise fit.

• Weld‑on installation—professional body shop recommended
• May require minor trimming or fitting shims for perfect alignment
• Sold as LH (driver) and RH (passenger) pair—no extra corner required
• Surface prep, seam sealer, and paint recommended after fitting

What comes in the package and how does this restore my truck?

You receive two cab corner panels—one left and one right—ready for weld‑on replacement. Replacing corroded or crushed corners reinstates proper body lines, protects the cab structure from further rust, and prepares the area for professional finishing and painting.

• Package includes one driver side and one passenger side cab corner
• Restores original cab corner geometry for door and bed alignment
• Provides a solid base for seam sealing and repainting
• Helps stop progression of rust and structural deterioration

Who is this for: These ECOTRIC cab corners are intended for owners, restorers, and collision repair shops working on 1999–2007 Chevrolet Silverado and GMC Sierra crew cabs (and some Suburban years) who need a heavy‑duty weld‑on replacement pair. If you have a crew cab with rusted, damaged, or missing rear cab corners and want a durable steel repair part ready for professional seam welding and finishing, this pair is a practical choice. Consider professional installation if you do not have welding and bodywork experience; Avalanche and other specialty trims may require additional modification.
