What makes these control arms better than the factory ones?

These UMI Performance control arms are made from stronger, tubular mild steel tubing and feature TIG welding, which eliminates the flex found in stock arms. They also use high-quality, grease-able polyurethane bushings to further reduce deflection and improve handling.

Do these control arms come with all the necessary hardware for installation?

No, these control arms are designed as a direct bolt-in replacement and utilize your vehicle's original hardware for installation. The necessary bushings, grease fittings, and sleeves are included.

How often should I grease the bushings?

It's recommended to grease the polyurethane bushings periodically to ensure they remain flexible and to prevent squeaking. A good practice is to grease them every oil change or every 5,000 miles, depending on driving conditions.
