GMC K3500 Seats & Seat Upholstery - OEM Fit Covers, Foam & Complete Seats

Transform the interior of your GMC K3500 with precision-crafted replacement seat upholstery or a set of complete assembled seats. Each upholstery kit is tailored from original factory patterns to ensure proper contour, seam placement, and an authentic look that fits your seats perfectly.

GMC K3500 seat kits are available in factory-correct vinyl, cloth, velour, or leather materials, each engineered for long-lasting durability and resistance to fading, wear, and stretching. Many options include pleated or stitched inserts, embossed patterns, and trim details that replicate the original interior design.

Prefer to start fresh? Complete reclining bucket seats are offered for many GMC K3500 applications, supplied with vehicle-specific bolt-in brackets so they install without drilling or fabrication. Choose a pair with brackets, a pair of seats only, or a single driver or passenger seat, in the style and color that suits your build.

Replacement seat foam, spring assemblies, rear seat covers, hardware, and matching panels are available for select models to complete your restoration.
