KSP Performance 2" Wheel Spacers for Chevy and GMC models (2011–2022) are designed to provide an aggressive stance while improving handling, stability, and performance. Precision CNC-machined from 6061 T6 aircraft-grade aluminum, these spacers are stronger and more durable than cast options, ensuring a long-lasting and reliable fitment. With a thickness of 2 inches (50mm), they provide ample tire clearance to prevent tires from hitting frame rails, allowing you to run larger tires for enhanced off-road capability. The spacers are equipped with pre-installed high-quality studs, with a 14x1.5 thread pitch, making installation easier and more secure. Ideal for 8x180mm bolt patterns on 2011-2022 Chevy Silverado/Sierra 2500HD/3500HD and GMC Sierra 2500HD/3500HD models. These spacers are built to ISO/DIN 10.9–12.9 grade specifications, using SCM435 steel material that has been heat-treated to avoid breaking under stress. Upgrade your vehicle with KSP wheel spacers for a bold new look and improved off-road performance.
