Cognito Motorsports SM Series Upper Control Arm Kit Silverado Sierra

The Cognito Motorsports SM Series Upper Control Arm Kit is a replacement and upgrade upper control arm set for Chevrolet Silverado and GMC Sierra trucks. It suits stock-height, leveled and lifted trucks. Cognito offers the line with ball joint or uniball designs and is sometimes listed as an SM Series UCA kit.

Key Features:

• Corrected ball joint angle: restores proper geometry on leveled and lifted trucks.
• Improved droop travel: allows more suspension droop, which helps ride quality and component life.
• Boxed sheet metal construction: arms are CNC robot welded for strength.
• Powder coated finish: semi-gloss black coating helps resist corrosion and gives a clean look.
• Polyurethane bushings: durable bushings are included with the kit, along with new crush sleeves.
• Quality joints: the kit includes Cognito alloy series ball joints or uniball joints, depending on the version.
• Made in the USA by Cognito Motorsports.

Cognito designs the SM Series for a straightforward bolt-on installation. Some versions add caster, and the manufacturer lists a DIY install time of about 1.5 hours on some versions. Cognito specifies a maximum torque of 50 ft-lbs on some versions, so follow the instructions included with your kit. Cognito Motorsports specializes in steering and suspension components for trucks and SUVs.
