1971-1981 GM Full Size (Impala, Delta 88, Electra)
The Metco Motorsports high performance lower control arms for the 1971-1981 GM Full Size 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 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: The center pins in the control arms are configured for use with the standard 9/16 mounting hardware.
In rare instances, it is necessary to enlarge the mounting holes at the chassis and/or the rear axle for installation. Installation instructions are included.
