This Synergy heavy-duty non-knurled adjustable ball joint kit is built for Jeep JK and WJ models. It replaces factory ball joints with adjustable units to correct alignment and accommodate lifted or modified front suspensions. The kit supports stronger steering articulation and lets installers fine-tune ride height and caster while retaining a sealed ball joint interface for road and trail use.
