See the "Vehicles it fits" section for the full list and engine details.
MOOG engineers its premium control arms for foreign and domestic nameplates with structural strength and corrosion protection in mind. This arm features:
- Carbon fiber bearing and hardened studs: Induction-hardened studs are paired with a patent-pending carbon fiber-reinforced bearing designed to reduce socket friction compared with typical non-reinforced bearings, for longer socket life. The hardening is intended to maximize stud strength, resist breakage and improve fatigue life.
- Greaseable socket with boot seal: New lubricant can be added to flush contaminants out, helping reduce corrosion and wear, while a pre-installed dust boot seal acts as a barrier against dirt, water and other wear-causing contaminants.
- Corrosion coatings: Specially engineered coatings on the metal surfaces help inhibit premature deterioration from rain, snow, salt and road grime.
- Pre-installed bushings: Their stiffness is optimized to help inhibit noise.
The arm comes with installation hardware, and its precision tolerances are intended to make installation and steering alignment easier. A laser-etched ID marks it as genuine MOOG. It is sold individually for the front left lower position; replacing both sides together is recommended.
