SPC heavy-duty GM offset upper ball joints feature a built-in 3-degree offset that can be clocked to affect camber, caster, or both—ideal for lifted or modified trucks that need extra alignment range. They also raise the outer end of the upper control arm to increase clearance and restore droop travel. SPC finishes these joints hex-chromate-free and subjects them to a 700-hour salt spray test. Note the factory arm strength limits tire size use.
