SPL Parts Upper Arms with Eccentric Lockouts (Rear) - Chevrolet Camaro 2016+

SPL Parts Upper Arms with Eccentric Lockouts (Rear) - Chevrolet Camaro 2016+ is a chassis-specific suspension upgrade engineered for drivers who want more precise geometry control from Chevrolet Camaro 2016+. SPL Parts is a U.S.-based performance-suspension specialist that develops motorsport-oriented chassis hardware for precise alignment, low compliance, and repeatable setup changes.

This upper suspension link replaces the factory arm with a more precise component intended to improve wheel-location control and, where adjustable, expand the usable alignment range. By reducing unwanted bushing movement, the upright follows the commanded geometry more closely under lateral load, helping preserve camber and toe behavior through fast transitions and sustained cornering.

Why it matters: On this application, the goal is to keep the tire and upright closer to the intended alignment as loads rise, giving the driver a more repeatable platform for braking, turn-in, mid-corner balance, and power application. The additional setup range is useful for lowered cars and wider tire packages that need alignment targets outside the factory adjustment window.

For best results, set the final geometry around the vehicle's tire, ride height, and intended street/track use rather than relying on generic factory targets.
