Product Details

Moog engineers premium control arms for foreign and domestic nameplates with an emphasis on strength and corrosion resistance. The RK641204 uses stamped steel construction, a painted finish, and rubber bushings to support stable rear suspension operation. This control arm is a direct-fit suspension component for vehicles that require a rear lower forward control arm, including 1997-2003 Chevrolet Malibu, 1999-2005 Pontiac Grand Am, 1999-2004 Oldsmobile Alero, 1997-1999 Oldsmobile Cutlass, 1990-1994 Chevrolet Lumina, and 2004-2005 Chevrolet Classic. This part cross-references Dorman OE Solutions 905-518 for the same application.

Common Problems This Part Helps Address

• Excessive rear suspension looseness
• Worn rubber bushings causing clunks or vibration
• Uneven rear tire wear from suspension movement
• Imprecise rear suspension alignment
• Corrosion-related control arm deterioration

Installation Notes and Tips

Verify rear lower forward fitment before ordering, since this control arm is application-specific. The RK641204 does not include a ball joint, grease fitting, or mounting hardware, so inspect related suspension components and reuse or source the required hardware as needed. Because the part uses rubber bushings, final tightening should be performed at normal ride height to help avoid premature bushing stress.

Quality Assurance

Moog suspension components are engineered for structural durability and corrosion protection across domestic and import applications. The RK641204 is built to meet OEM-level expectations for the listed Chevrolet, Pontiac, and Oldsmobile fitments.
