Product details:
These work great on vehicles used primarily for cruising and long distance events. Configured for QA1 Pro Coil Systems, these street control arms feature powder coated tubular construction for increased strength and great looks. 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. Part #52421 is only for use with QA1's Pro Coil System. QA1's GM A, G and F-Body control arms are also offered in race configurations for added performance.
