QA1 offers Mopar A, B and E-Body control arms with sway bar tabs. These lower control arms are a direct bolt-in on your factory k-member and are twice as strong as factory arms and don't add any weight. The set includes bushings, pivot arms and nuts for ease of installation. Made in the USA.
Sounds to me like you get pretty much nothing out of them versus just buying the $20 stiffening plates for the factory control arms. Maybe you're car will be faster due to the driver now having a lighter wallet.
