Explorer Pro Comp Outer Tie Rod End Kit # 90-40231B is designed to replace a worn out component. This Tie Rod End is only for use on 2007 through 2021 Toyota Tundra already equipped with the Pro Comp 6" Stage 1 or Stage 2 Suspension lift system. The Pro Comp 6" suspension lift utilizes a unique tie rod end with a special "bend" profile to safely clear the steering and suspension components. This means means factory style tie rod ends will NOT work with the Pro Comp 6" lift systems! If your Tundra has worn out tie rod ends it means your alignment cannot be adjusted and set properly. Worn out parts means bad steering control and can cause uneven tire wear.
Please Read: The 90-40231B is the replacement "kit" that includes 2 tie rod ends and cotter pins. This item is a direct fit for the 90-4229 part number. The part number is different as this is a boxed "kit" and not just an individual part.
