The Metco Motorsports upper control arm is comprised of two precision-machined aluminum blocks each housing a threaded steel pinion, and a heavy-duty zinc-plated adjuster. 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 polyurethane 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 Grade 8 hardware, grease fittings for all four pivot points, and installation instructions.
Important Note: As shipped, this control arm set is configured for (and includes) 9/16" mounting hardware. If your vehicle uses larger 5/8" hardware, please contact us so your arms can be assembled accordingly.
