The Metco Motorsports high performance lower control arms for the 1971-1981 GM full size cars are CNC-machined from 6061-T6511 billet aluminum for unsurpassed strength and precision-fit. The control arms are clear-anodized for long-lasting surface protection.
Our control arms are designed to be installed as a direct replacement for the factory control arms, but offer the benefits of the dramatically stronger billet design and Energy Suspension-brand high-graphite polyurethane bushings. Each bushing has a grease fitting for long term, noise-free service. In most cases, no modifications to the vehicle are required for installation, although compatibility with the factory rear sway bar is unconfirmed.
Note 1: The center pins in the control arms are configured for use with the provided 9/16" mounting hardware. In very rare instances, it is necessary to enlarge the mounting holes at the chassis and/or the rear axle for installation. Installation instructions are included.
Note 2: These control arms are offered in an extended-length configuration for custom applications. This kit is available under PN MCA0013EXT, and includes the corresponding extended-length upper control arms. This extended-length kit is listed elsewhere in this
