The Tera Flex JK high steer knuckle is cast from heavy duty ductile iron and features reinforcements in key section areas that are prone to stress and deflection, and provides a heavy duty solution for several weak vulnerabilities found in the stock JK axle steering configuration. This kit is designed to work perfectly on JK Wranglers with 4-6" of lift, and will maintain steering geometry at the correct angles for superior highway drivability and increases tie rod ground clearance by over 1-1/8" to reduce tie rod damage and bending. This kit includes one driver high steer knuckle and one passenger high steer knuckle. Fits all JK Wrangler models including Rubicon and Unlimited.
