2019-2025 GM 1500 6mm Wheel Spacers (SPC6MM6139GM106)

The ReadyLIFT 6mm Wheel Spacers for the 2019-2025 GMC/Chevy 1500 are precision-engineered solutions designed to help truck owners install aftermarket wheels that may otherwise interfere with the brake caliper boss. These CNC-machined billet aluminum spacers provide a safe 6mm of offset, allowing for necessary clearance without the need to modify factory wheel studs. Ideal for those who want a subtle adjustment to avoid wider 1-inch spacers, this pair ensures a perfect hub-centric fit for optimal safety and performance.
