Upgrade your Alpha chassis ATS with our ZZPerformance billet aluminum rear control arm kit, engineered for serious gains in strength, handling, and appearance over the factory stamped steel components. Each arm is CNC-machined in-house from aircraft-grade 6061 aluminum and paired with high-quality chromoly, Teflon-lined rod ends for maximum durability, precision, and reliability.

By replacing the factory rear toe link and control arms, this kit significantly reduces flex, minimizes unwanted toe change under acceleration and braking, all while also eliminating rubber bushing deflection resulting in more consistent, predictable handling. Whether you race at the drag strip, on road course, or drive spirited around town you will notice a drastic difference over stock.

Designed as a direct bolt-on upgrade, the arms come pre-set to factory specifications for easy installation. For fine-tuning, the adjustable rod ends allow you to dial in your suspension geometry to match your specific setup. 

Fits: 2013-2019 Cadillac ATS, 2016-2019 Cadillac ATS-V, 2014-2019 Cadillac CTS, and 2014-2019 Cadillac CTS V-Sport.
