Genuine GM Rear Upper Control Arm — Chevrolet Corvette C8 (2020-2024)

The Rear Upper Control Arms are an integral part of the highly sophisticated multi-link rear suspension system in the Chevrolet Corvette C8. Working in perfect harmony with the lower control arms, these upper links precisely control the rear wheel’s camber angle and manage its vertical travel during compression and rebound. Since the C8 utilizes a high-performance mid-engine layout, these upper arms are engineered to withstand immense lateral cornering forces, keeping the rear tires planted firmly to the tarmac. Being GM Genuine OEM parts, they provide the exceptional structural rigidity required for track use while maintaining a lightweight design to optimize overall vehicle dynamics.

Technical Specifications

Technical Note: The rear upper control arm directly dictates your vehicle's rear wheel camber curve. Performing a highly precise, professional four-wheel suspension alignment is absolutely vital immediately after replacement. Even a minor deviation in the static camber angle alters the tire's contact patch with the road, which can reduce rear-end grip under hard acceleration or compromise cornering predictability.

Pro Tip: When securing the new control arm, it is critical that all chassis bolts are tightened only while the suspension is at its normal static ride height (loaded), and torqued strictly to factory specifications. Tightening these bolts while the suspension is fully drooped (hanging on a lift) will twist and damage the internal rubber bushings, leading to premature bushing failure.
