OXILAM Under-Seat Vent Deflectors for Chevy Silverado & GMC Sierra 2014–2019, 2-Piece 45° Pre-Angled PC Plastic

These under-seat vent directional deflectors are designed for 2014–2019 Chevrolet Silverado and GMC Sierra trucks to change the angle of rear air outlets without any modification. Molded from durable PC plastic with internal fins, they snap into the factory outlet ports and aim conditioned air toward occupants for improved comfort. Two differently sized pieces are included to match the driver and passenger-side rear vents.

How do these deflectors install—do I need tools?

Installation is plug-and-play: each deflector shares the original connection port and is pre-angled 45° to lift airflow upward. No trimming, screws, or adhesive are required; simply press the deflector into the outlet until it seats securely.

• No tools required—pop into place by hand.
• Pre-angled 45° outlet guides air toward rear passengers.
• Two-piece kit matches left and right rear outlets.
• Fits factory-sized AC exhaust ports for 2014–2019 models.

Will these deflectors hold up over time?

OXILAM builds the deflectors from rigid PC (polycarbonate) plastic that resists deformation and retains shape under cabin temperatures. Internal fins add structural strength and maintain directional flow even after repeated use.

• Hard PC plastic resists warping and cracking.
• Internal fins support consistent airflow direction.
• Durability designed for long-term in-vehicle use.
• Simple shape minimizes stress points that can fail.

Which trucks and vents are these compatible with?

The kit is intended for Chevrolet Silverado and GMC Sierra model years 2014–2019 that have rear under-seat air outlets. Before ordering, confirm your truck includes rear backseat vents since some trims or aftermarket changes may not have the factory outlet.

• Designed for 2014–2019 Chevrolet Silverado and GMC Sierra.
• Two sizes included: 6.6 x 0.9 inch for passenger side, 5.5 x 0.9 inch for driver side.
• May fit other GM vehicles with the same outlet geometry.
• Not suitable if your truck lacks rear under-seat vents.

What comfort improvements can I expect for rear passengers?

By redirecting air upward into the seating zone instead of the floor, the deflectors make temperature control more effective for people riding in the back. The change is most noticeable when cooling or heating is running and when rear passengers report uneven airflow.

• More air reaches occupants seated behind the front row.
• Reduces wasted airflow that otherwise goes to floor space.
• Improves perceived cabin comfort during climate control cycles.
• Helps even out rear temperature distribution without changing settings.

Who is this for? Drivers and fleet owners of Chevrolet Silverado and GMC Sierra trucks (2014–2019) who want a low-cost, noninvasive way to improve rear-seat comfort. It’s ideal for families, rideshare drivers, and anyone who notices rear passengers feel the AC or heat primarily at their feet. Check your truck’s under-seat vents before purchase to ensure compatibility.
