This arm is part of MOOG's premium line for foreign and domestic nameplates, engineered for structural strength and corrosion protection. MOOG selects the material and heat treatment to meet the requirements of each application.
- Induction-hardened studs: hardened to maximize strength, resist breakage and improve fatigue life.
- Pre-installed dust boot seal: forms a barrier that helps keep wear-causing dirt and water out.
- Added corrosion protection: specially engineered coatings on the metal surfaces help inhibit premature deterioration from rain, snow, salt and road grime.
- Premium bushings: pre-installed, with stiffness optimized to help inhibit noise for a comfortable ride.
It comes with the hardware needed for installation. Its precision tolerances are designed to make installation and steering alignment easier. As with any suspension repair, have the alignment checked once the new arm is in place.
