2014-2018 CHEVROLET SILVERADO SIERRA DENALI FRONT & REAR GRAY LEATHER SEATS

2014–2018 Chevrolet Silverado and GMC Sierra (K2XX platform), the premium leather seating found in the Denali and high-trim SLT/LTZ models is highly sought after for interior upgrades and restorations. The Dark Ash Gray leather was a popular choice, providing a sophisticated contrast to the standard black interiors.

Technical Specifications & Features

The Denali-specific seats are distinguished by higher-grade materials and unique stitching patterns compared to the standard LT or SLE trims.

Material: Perforated Mulan or Nappa leather covers, designed for both durability and airflow.
Adjustment: Typically 12-way power-adjustable driver and passenger seats with power lumbar support.
Climate Control: Equipped with Heated and Ventilated (Cooled) functions.
- Note: The ventilation system uses internal fans within the seat back and cushion to pull cabin air through the perforations.
Safety: Integrated side-impact airbags are located in the outer bolsters of both front seats.

Inventory Inspection Checklist

If you are cataloging or evaluating a set of these seats for resale or restoration, check the following common wear points:

Driver’s Side Bolster: Check the outer foam for “pancaking” or collapse, which is common from drivers sliding in and out of the truck.
Heating Elements: The heating grids in the 2014–2018 generation are known for potential shorts. Testing the resistance of the heating pins with a multimeter is a standard professional practice.
Plastic Trim (Bezels): The plastic side shields housing the power seat switches are prone to cracking if stepped on during entry.
Memory Module: Ensure the Memory Seat Module (MSM) under the driver’s seat is present, as it controls the presets for the mirrors, steering column, and seat position.

Gray Color Variations

GM offered a few variations of gray that can look similar in photos:

H2U (Jet Black / Dark Ash): A dark, charcoal-leaning gray often paired with black trim.
H2V (Dark Ash / Jet Black): A lighter gray centerpiece with black accents.
H4R (Cocoa / Dune): While not gray, in certain lighting, “Dune” can appear as a warm, light taupe/gray.
