This Synergy knurled front ball joint set is specified for Jeep JK and WJ front Dana 30 and Dana 44 axles. As a heavy-duty replacement set, the knurled bodies secure the joints in the control arms to resist rotation and enhance retention under load. The set is intended to restore steering geometry and reliable front suspension pivoting for vehicles that see demanding use or have modified suspension geometry.
