74-77 GM Lower Control Arm Bushing Kit

The MOOG 74-77 GM Lower Control Arm Bushing Kit (K6109) is an essential wear item for anyone restoring, maintaining, or upgrading suspension performance on mid-1970s General Motors vehicles. Lower control arm bushings are the elastomer and metal components that isolate the control arm from the frame, absorbing road shock and preventing metal-to-metal contact that degrades handling and accelerates wear on associated suspension components. Original equipment bushings on these classic GM platforms deteriorate from heat cycles, UV exposure, and constant articulation over 45+ years, resulting in excess play, clunking, and unpredictable steering response that compromises both safety and driver confidence.

MOOG is the industry standard for OEM-equivalent and performance suspension components, and the K6109 kit delivers factory-correct fitment and durability for lower control arm applications on these vehicles. This kit contains both upper and lower bushings pre-assembled into the control arm geometry, eliminating the need for specialized pressing tools and ensuring precise alignment during installation. The rubber compound is engineered to withstand temperature fluctuations and repeated loading cycles while maintaining compliance, whereas worn original bushings allow lateral movement that increases tire wear rates and destabilizes the vehicle under acceleration or cornering. MOOG's quality control and materials science mean these bushings restore the suspension compliance and articulation range designed by GM engineers.

Mechanics and enthusiasts restoring 1974–1977 Chevrolet, Pontiac, Oldsmobile, and Buick models will find the MOOG K6109 kit indispensable for full suspension rehabilitation, whether performing a complete frame-off restoration or addressing mid-cycle clunking and vagueness in the steering. This kit is compatible with the lower control arm assembly on these platforms and is best installed as part of a comprehensive suspension service that includes wheel alignment after bushing replacement. DIY installers should expect straightforward removal and installation if press tooling is available; professional shops typically complete the job in under two hours per side, and the compact 1.5 lb package ships easily for both retail and fleet applications.
