QA1 Precision Products Insert Stock Coil-Spring Mount Kit Early GM Lower Control Arm
QA1's GM A, B, G, X 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 hardcore 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.
All parts sold in pairs and including mounting hardware. Made in the USA.
These control arms are also offered in street configurations for cruising and long distance events.
