2x Fit 2014-2019 GMC Sierra Air Passenger&Driver Rear Deflectors Accessories

45° Longer Edition Pair (L+R) Scratch-Resistant Lifetime Warranty Made in USA

Product Overview

Modern pickup cabs are engineered for comfort, but the rear air vents located under the front seats often fail to deliver airflow where it's needed most. Carpeting and seat positioning can partially block those vents, leaving rear passengers without adequate climate control — especially on hot days or long road trips. These 45-degree air deflectors solve that problem by redirecting airflow upward and outward, ensuring the air actually reaches the second row instead of being swallowed by the floor.

Designed specifically for 2014–2019 GMC Sierra 1500, 2500HD, and 3500HD models (as well as the mechanically identical Chevy Silverado of the same generation), each deflector snaps directly over the existing vent outlet under the front seats. No cutting, drilling, or permanent modification is required. The precision-molded plastic construction matches the factory contours and includes a scratch-resistant, waterproof surface that withstands repeated kicks from rear-seat passengers without fading or cracking.

Whether you frequently transport family, coworkers, or gear that needs cooling, this pair of deflectors transforms your rear climate performance at a fraction of the cost of a dealer solution. The slightly extended design — 5 ¼″ on the driver side and 6 ¼″ on the passenger side — ensures full coverage even with the front seats pushed well back. Add a layer of comfort to your Sierra or Silverado with an upgrade that installs in under five minutes and pays dividends on every drive.

Key Features & Benefits

✔ Precision 45° Deflection Angle
Redirects under-seat airflow upward and rearward, eliminating blocked or dead zones so rear passengers feel the air — not just the floor carpet.
✔ Extended Length for Seats-All-the-Way-Back
Driver-side deflector measures 5¼″ × 11/16″ and passenger-side 6¼″ × 11/16″ — a 45° longer edition that reaches past carpet pile even when the front seats are fully reclined.
✔ Scratch-Resistant & Waterproof Construction
Durable black plastic shrugs off dirt, moisture, and incidental kicks from second-row occupants, keeping your cabin looking clean and factory-fresh year after year.
✔ Tool-Free, No-Drill Installation
Simply align the deflector over the existing vent and press into place — no screws, adhesives, or modification required. Installs in under 5 minutes per side.
✔ Full Pair — Driver & Passenger Included
Both left and right rear air deflectors are supplied in one package, so both front-seat under-vent outlets benefit from improved airflow direction immediately.
✔ Lifetime Manufacturer Warranty
Backed by a lifetime warranty against defects in materials and workmanship — install with total confidence, knowing your purchase is protected for as long as you own the vehicle.

Installation Guide

Difficulty: ★☆☆☆☆ (Very Easy)  |  Time: 5–10 minutes total  |  Tools Required: None — purely hand installation. A flashlight is helpful to locate the vents under the seats.

1
Slide the front seat fully forward. Move the driver's or passenger's seat all the way forward on its tracks to expose the rear under-seat area. On power seats, use the forward switch; on manual seats, pull the release bar and slide forward.
2
Locate the rear air vent outlet. Look under the seat cushion near the floor — you'll see a rectangular plastic vent grille pointing toward the rear. In some trucks, carpeting may slightly overlap the vent; pull the carpet back if necessary.
3
Select the correct deflector. The shorter deflector (5¼″) fits the driver-side vent; the longer deflector (6¼″) fits the passenger-side vent. Lay them next to the corresponding outlet to confirm orientation.
4
Align the deflector with the vent opening. Hold the deflector at a slight angle and fit its inner lip over the top edge of the factory vent grille. The curved vane should face upward and slightly rearward.
5
Press firmly into place. Apply even pressure to the center of the deflector until you feel it snap onto the vent grille. A click or snug seat confirms proper engagement. Do not use excessive force — if it doesn't seat easily, re-check orientation.
6
Return the seat to your driving position and test. Slide the seat back, turn on the HVAC fan (set to floor/panel mode), and confirm that air is now flowing upward through the deflector rather than being trapped under the seat. Repeat for the opposite side.
