This inner cover attaches to the vehicle’s bracket assembly (typically near the front or rear bumper) to shield internal components (e.g., wiring, hoses, mounting hardware) from dust, debris, water, and road salt. Crafted to match OEM standards, it not only ensures long-term durability of your Silverado’s undercarriage but also maintains the truck’s factory-approved structural integrity—making it an essential replacement part for worn or damaged original inner covers.
The inner cover is engineered to act as a barrier against road hazards: it prevents small rocks, mud, and water from infiltrating the bracket assembly, protecting sensitive components like wiring harnesses and hydraulic lines from damage or corrosion. The cover’s contoured shape also redirects airflow, reducing debris buildup in hard-to-reach areas.
Made from high-density polyethylene (HDPE), the 19silverado Bracket Assembly Inner Cover JS23-078 offers superior strength and flexibility. HDPE is resistant to impact, chemical degradation (e.g., road salt, oil), and extreme temperatures (-30°C to +70°C), ensuring the cover retains its shape and functionality for years.
The cover features pre-drilled holes and integrated mounting tabs that align perfectly with the 2019 Silverado’s existing bracket assembly. This design eliminates the need for custom modifications, ensuring a quick and secure installation that matches the factory fit.

The 19silverado Bracket Assembly Inner Cover JS23-078 is fully compatible with the 2019 Chevrolet Silverado 1500 (all trim levels, including LT, LTZ, and High Country). It is designed for use with the truck’s front or rear bracket assemblies (confirm your vehicle’s specific bracket location via the owner’s manual or Chevrolet dealer). This inner cover is not compatible with Silverado 2500HD/3500HD models or 2020-2023 Silverado 1500 variants, as their bracket assembly dimensions differ.
Socket wrench set (10mm and 12mm sockets)
Torque wrench (optional, for OEM-spec tightening)
Wire brush (to clean rusted or dirty mounting bolts)
Microfiber cloth
Raise your 2019 Silverado using a jack and secure it with jack stands (never work under an unsupported vehicle). Locate the bracket assembly (front: near the front bumper; rear: near the rear bumper) and clean the area with a wire brush to remove rust or debris.
If replacing an old inner cover: Use a socket wrench to remove the factory bolts securing the old cover to the bracket assembly. Carefully remove the old cover, taking note of the mounting tab positions for proper alignment.
Position the 19silverado Bracket Assembly Inner Cover JS23-078 over the bracket assembly, aligning its pre-drilled holes with the factory mounting points. Ensure the cover sits flush against the bracket to maximize protection.
Insert the included mounting bolts (or reuse factory bolts if in good condition) and tighten them with a socket wrench. For optimal safety, torque bolts to 8-10 N·m (follow OEM specifications if provided).
Lower the vehicle and inspect the inner cover to ensure it is securely mounted and free of gaps. Test drive the truck to confirm no rattling or movement.
Approximately 30 minutes; basic mechanical knowledge recommended.
1-Year Manufacturer Warranty: Covers defects in material (cracking, warping) and workmanship, providing replacement or repair for qualifying issues.
Impact Testing: The HDPE material undergoes drop testing from 1.5 meters to ensure resistance to minor impacts (e.g., debris kicks up).
Environmental Testing: The inner cover is tested for UV resistance (1,000 hours of UV exposure) and chemical resistance (exposure to road salt and oil) to ensure long-term performance in harsh conditions.
OEM Compliance: Meets Chevrolet’s strict quality standards for undercarriage components, ensuring compatibility and safety.
