The stock "bushing" type king pins and bushings were fine on your old car when it had drum brakes and only ran 50 mph. But now you've put an 11" disc brake kit and 400hp to the old girl. The upper king pin bushings take a tremendous amount of abuse and wear from added strain.
These "Royal" king pin kits feature dual needle bearings at both top and bottom and stainless steel king pins. Easy to install and includes the special tool required.
