      Improves Performance and Handling. If you have a lifted Jeep, the Teraflex High Steer Knuckle Kit for 4-plus-inch Lift is a great investment. It helps improve the Jeep Wrangler JK's off-road performance by eliminating the stock knuckle weaknesses with its reinforced design. Furthermore, the High Steer Knuckle kit also maintains the proper steering geometry angles for superior highway drivability.

      Superior Construction. Like other Teraflex products, the High Steer Knuckle Kit is designed and built for performance and durability. Featuring a reinforced design and heavy-duty ductile iron construction, these knuckles can withstand extremely rugged conditions.

      Some Welding Required. The High Steer Knuckle Kit is a direct fit, but requires some welding for superior off-road strength. It also requires aftermarket wheels with 4.50-inch backspacing and either an HD or standard Flipped Drag Link.

      Limited Lifetime Warranty. The High Steer Knuckle Kit is warrantied to be free of defects in materials or workmanship for as long as the original purchaser owns the vehicle the product was originally installed on. Exclusions will apply.

      Application. The Teraflex High Steer Knuckle Kit for 4-plus-inch Lift is designed for lifted 2007 to 2018 Jeep Wrangler JK models.

        Great addition!

        These were easy to install and raise the tie rod for better ground clearance. I reccomend installing new ball joints while installing these since your dissasembled that far anyway.
