Double-Adjustable Upper Control Arm Set
For GM Full Size Cars, Stock Length
1971-1981 Impala, Delta 88, Electra
The Metco Motorsports upper control arm is comprised of a precision-machined aluminum block housing a threaded steel pinion, a heavy-duty zinc-plated adjuster, and a precision-welded and powdercoated clevis. The combination of these premium components results in a control arm that can be installed as a direct replacement for the factory control arms, but offers the benefits of in-car adjustability, the firm response of polyurethane bushings, and an independently-verified 400% increase in strength.
The Metco control arms require no disassembly for adjustment, and the user can even dial in the pinion angle with the vehicle's weight on the suspension. Prior to shipment, the arms are assembled on a jig and carefully set to match the length of the stock control arms for the intended application. No adjustment is required by the installer.
Energy Suspension-brand high-graphite polygraphite bushings are included for all pivot points to provide a ride quality befitting a high performance vehicle without the harshness of rod ends or heim joints. The design of the Metco control arm also provides additional clearance for oversize exhaust pipes routed over the axle.
The control arm set includes polyurethane bushings to replace the bushings in the differential ears, the necessary hardware, and comprehensive installation instructions.
Note: These control arms are offered in an extended-length configuration for custom applications. This extended-length kit includes the corresponding extended-length lower control arms. This kit is available under PN MCA0013EXT, and is listed elsewhere in this section.
