This set of 4 forged wheel spacers is designed for a variety of GM vehicles, including the 1999-2026 Cadillac Escalade, Chevy Silverado 1500, Chevy Tahoe, Chevy Suburban 1500, Chevy Avalanche 1500, and more. Made from durable 6061 T6 aircraft-grade aluminum, these spacers are stronger and more durable than cast alternatives.
