KPALAG 2PCS Upgraded Back Panel Air Vent Relief Grille

KPALAG 2PCS Back Panel Air Vent Relief Grille is a direct-fit replacement cabin pressure vent assembly designed to restore proper venting and sealing on compatible Chevrolet and GMC trucks.

This pair of vent relief grilles (replace#: 13596856) is molded from durable polypropylene with rubber baffles using an over-molding process for improved longevity and a tight seal. Built to match OE fit and function, the grilles snap into the back panel vent openings of numerous Silverado, Sierra, Colorado and Canyon models so you can replace cracked, warped, or missing vent assemblies quickly and without modification.

Which truck models and years will these vent grilles fit?

These KPALAG grilles are engineered to fit a wide range of Chevrolet and GMC trucks across multiple years. Check your vehicle’s compatibility list before ordering to confirm fitment for front-rear back panel vent locations.

• Chevrolet Silverado 1500 and 2500, model years 1999–2019 (varies by submodel)
• Chevrolet Silverado 3500, 2001–2006 and select HD years
• GMC Sierra 1500, 2500, 3500 across 1999–2020 ranges and Classic/HD variants
• Chevrolet Colorado and GMC Canyon 2015–2021

How durable and sealed are these replacement vent parts?

KPALAG uses high-quality PP for the grille frame and superior rubber for the baffle, offering toughness, wear resistance and corrosion resistance. The over-molding manufacturing creates a seamless bond for improved durability and an all-around seal to minimize gaps and wind noise.

• Polypropylene frame resists cracking and outdoor exposure
• Elastic rubber baffle retains shape and resists wear
• Over-molded join for long service life and fewer failures
• Pre-shipment inspection performed; allow minor flap settling after transit

Is installation difficult and what tools do I need?

Installation is straightforward: these grilles are manufactured to meet fit, form, and function standards for a direct replacement. No special tools or bodywork are required; most installs are a simple snap-in or press-fit process performed from the interior panel opening.

• Direct replacement part—matches original vent opening dimensions
• Push-in or snap-fit installation—no cutting or drilling
• Two grilles included for pair replacement or spares
• If flaps appear misaligned after shipping, place them with flaps upward for a day to reset

What should I expect when I receive the grilles?

Each order contains two back panel air vent relief grilles as pictured. Items are inspected before shipment; occasional transit pressure can cause the rubber flaps to sit slightly askew. That condition typically corrects itself after a short period of rest in the upright position.

• Package includes 2 × KPALAG back panel vent grilles
• Replace#: 13596856 for quick cross-referencing
• Minor shipping-induced flap gaps can be remedied by simple rest
• Matches OEM fit for ease of replacement and clean appearance

Who is this for: vehicle owners or mechanics who need a reliable, budget-friendly replacement for damaged or missing back panel air vent relief grilles on Chevrolet Silverado, GMC Sierra, Colorado and Canyon trucks. Ideal for restorations, collision repairs, or routine maintenance when you want a close OE-fit part without extensive installation time.
