Tie Rod Reinforcement Kits are designed to strengthen the slender OEM tie rods. OEM Tie rod ends can bend or even break under force, usually caused by larger wheels and tires that are generally purchased after lifting a vehicle, or especially if you're offroading. The thick walls of the steel sleeves thread onto the existing tie rod and provide support up the entire tie rod shaft and will even work with replacement OEM tie rods, or ones which have adjustments on the end of tie rod end. Installs in less than one hour. No alignment will be necessary upon completion if installed properly.
