When changing out your truck's wheel bearing the bolts attach the spindle to the wheel bearing, requiring 133 ft/lb of torque for the installation process. It is recommended you change out these bolts when you're swapping out the wheel bearing to ensure proper performance for every situation. These bolts are notorious for rust and corrosion which is exactly why Kryptonite plated each one of these bolts in zinc to prevent any oxidation. These are bolts are sold individually so you'll need 6 in total for a 6 Lug truck and 8 in total for an 8 Lug truck. Best of all, even these bolts are backed by Kryptonite's No Fine Print Lifetime Warranty to help keep your investment protected. Vehicle Fitment:
