Lower race control arm kit for 82-04 GM S Series. Includes ball joints and bushings. Bolt-in spring adapter needed for use with stock springs.

QA1’s GM A, G and F-Body and S Series Truck Race Control Arms utilize a QA1 Low Friction Ball Joint and low friction, low deflection pivot bushings, providing the added performance needed for drag racing, pro-touring and hard core street applications. These control arms feature powder coated tubular construction for increased strength and great looks and come configured for QA1 Pro Coil Systems. A bolt-in spring adapter is available separately to allow the control arms to be used with stock springs. All of the upper arms feature an offset cross shaft letting you quickly and easily adjust camber. All of these arms are designed to add 3-4 degrees of caster and 0.5 to 1 degree of negative camber when used together. When used independently they will add approximately half of the preceding numbers.
