Good To Know

Q: Do I need an alignment after installing these arms? A: Yes, a professional alignment is recommended after replacement since suspension geometry changes once new arms and ball joints are fitted.

Q: Can I install this pair with basic hand tools? A: Most installations need a ball joint separator, torque wrench, and jack stands, and a press is not required because the joints come pre-installed.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
