The TeraFlex JK: Dana 30/44 High Steer Knuckle Kit addresses several weaknesses prevalent in the stock axle steering configuration on JK Wrangler/Unlimited models with 4-6” lift kits.
These High Steer Knuckles maintain correct steering geometry angles for superior highway drivability. Tie Rod ground clearance is increased by more than 1-1/8” to prevent tie rod damage and bending. Cast from heavy-duty ductile iron and reinforced in areas prone to stress and deflection.
Compatible with all factory and aftermarket axle shafts, ball joints, wheel hubs, and tie rods. Does not affect operation of factory stability and traction control systems including ESP and ABS.
