Front Driver Side Upper Control Arm with Ball Joint

Complete Suspension Assembly for Chevrolet Colorado and GMC Canyon

Restore factory-spec handling and steering precision to your mid-size truck with this Premium Front Upper Control Arm. Designed as a direct-fit replacement for the driver side, this assembly comes complete with a pre-installed ball joint and bushings. This "bolt-on" solution eliminates the need for a hydraulic press, significantly reducing labor time and ensuring all components are perfectly aligned and seated from the factory.

Constructed from high-strength steel, this control arm is built to withstand the rigorous demands of truck suspension cycles, maintaining proper camber and caster angles for even tire wear. The integrated ball joint features a precision-machined mounting for a secure fit into the steering knuckle, while the maintenance-free design ensures long-lasting performance without the need for periodic greasing.

Fitment Verification and Vehicle Applications

This control arm is engineered for the Front Upper Driver Side (Left) on the following vehicles:

• Chevrolet Colorado: 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022.

• GMC Canyon: 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022.

Installation Note: This part is designed for trucks with standard ride height. If your vehicle has a leveling kit or suspension lift, please verify that your geometry remains within the operating range of a standard-length upper control arm to prevent accelerated wear on the ball joint boot.

Installation and Technical Tips

• The "Ride Height" Rule: To maximize the life of your new bushings, do not fully torque the control arm pivot bolts while the truck is supported by a jack. Lower the vehicle to the ground so the suspension is at its natural ride height, then perform the final tightening. This prevents the rubber from being "twisted" or pre-loaded, which causes premature tearing.

• Professional Alignment Required: Replacing a control arm changes your vehicle’s alignment geometry. A professional four-wheel alignment is mandatory immediately following installation to prevent rapid tire wear and ensure the steering wheel is centered.

• Inspect the Passenger Side: Suspension components generally wear at the same rate. If the driver side bushings are cracked or the ball joint has play, the passenger side likely requires replacement as well to maintain balanced handling.

• Safety Check: Ensure the ball joint stud is fully seated and the cotter pin is properly bent through the castle nut. A loose ball joint can lead to a catastrophic loss of steering control.
