QA1 GM 2.0 Drag Race Control Arms 52937 1964-1972 GM A-Body

QA1 Control Arm 2.0 was designed to be the lightest, strongest, and best-looking control arms available for your ride.

Uniquely engineered with key features optimized for either street performance, pro-touring, or drag race vehicles, these American-Made control arms will ride better, corner harder and launch faster than anything you’ve experienced in the past. 

In addition to improved geometry, each configuration has unique features to optimize performance for the intended use.

QA1’s race control arms are designed for drag racing, pro-touring and autocross applications. They’re equipped with QA1’s exclusive X-Series Chromoly rod ends and low friction ball joints. This gives you a wide range of wheel alignment settings while reducing friction.

QA1 GM 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.
