SPC Performance 23960 Gm Offset Upper Balljoint

These heavy duty offset ball joints have a built in 3 degree offset which can be clocked to affect camber, caster, or both. They are ideal for vehicles which cannot be aligned properly with the factory cam bolts due to installation of a lift or levelingkit. As an additional benefit, they also raise the outer end of the upper control arm, which increases clearance between the arm and the droop travel stops on the frame. This restores droop travel on trucks with leveling kits, and eliminates noise vibration harshness caused by arm to frame contact. Note: Due to strength limitations of the factory upper control arm, this ball joint should not be used on trucks with tires larger than 33" unless a "tall knuckle" lift kit is installed.
