Improve the street and track performance of your G-body with our P/N 3033-1 upper a-arms. These a-arms feature a ½” taller premium ball joint that enhances the suspension travel and provides a precise Pro-Touring feel. The relocated ball joint plate allows for up to six degrees of caster without the need for excessive shimming, while the taller ball joint creates up to one additional degree of negative camber at full bump travel. This results in improved steering feel and increased lateral grip. These track-tested a-arms are made in the USA and come with greaseable Delrin bushings, chromoly cross shafts, improved header clearance, and polyurethane bump stops. They are finished with a durable gloss red or black powder coat finish to maintain their appearance on your vehicle.
