These knuckles are fully welded and ready to install. Please specify which knuckles you have and if the upper ball joint and lower ball joint bolts are vertical (like most factory configurations) or horizontal.
 
These knuckles are significantly stronger han factory and standard gussetted spindles and adds double shear tabs for heim steering. This kit corrects bump steer from heim joint outer tie rods, adds adjustability to steering curve geometry, and increases steering force at the tires!
