These are hub-centric so they are completely safe when installed properly, we use these on our personal vehicles.
Bigger tires need clearance and adding that suspension lift is only half the battle. Spidertrax 1.25" thick, 6061T6 aluminum spacers are an easy way of spacing out front and rear late model Toyota axles that run hub-centric wheels (wheels using shank style lug nuts). This added spacing is necessary for keeping those larger tires from crashing into your frame rails and suspension links at full turn. Simply bolt-on like a wheel, and off to the trails you go.
Each kit comes with 2 wheel spacers, wheel studs (pre-installed), 12 lug nuts, and a package of thread locker. Each wheel spacer is anodized in blue or black, using a double anodizing process for twice the corrosion resistance. In addition, each wheel spacer is wheel and hub centric for a perfect fit.
