These 5 on 5", 6061T6 aluminum spacers are an easy way of spacing out front and rear Jeep Wrangler JL & 11-18 Jeep Grand Cherokee axles by 1 3/4", allowing for larger more aggressive tires. Each kit comes with 2 wheel spacers, 10 standard wheel studs (pre-installed), 10 lug nuts, and Loctite. Wheel spacers are anodized in dark blue, using a double anodizing process for twice the corrosion resistance. In addition, each wheel spacer is wheel and hub centric for a perfect fit.
