Description

Designed for the pro-touring GM enthusiasts, QA1 GM 2.0 pro-touring control arms are a simple upgrade over original suspension or worn and outdated tubular control arms. The pro-touring arms are also for those wanting to improve their overall handling, ride quality, and vehicle stance. These arms will improve suspension geometry over the factory configuration and pave the way for planning additional upgrades. The high-strength, low alloy steel enables optimized thinner wall construction and results in overall lighter weight. The increased positive caster design improves straight line stability. Pro-touring arms also feature QA1's stronger, low maintenance, and rebuildable ball joints which feature integrated dust boots.

Note: These control arms are not compatible with OE-type springs, a coilover system must be installed. QA1's arms will accept factory type sway bars and include upper and lower bump stops.

Product Overview

QA1?s Pro-Touring Control Arms are the answer to your handling needs for autocross and road course. Designed with QA1?s Ultra Low Friction Ball Joint, these arms will eliminate flex and provide bind-free movement. The one inch longer upper ball joint stud improves camber gain to keep the tire contact patch optimal for superior cornering grip. QA1?s ball joints are adjustable and rebuildable for tuning with different stud lengths. Configured for QA1 Pro Coil Systems with double shear lower mounting. The combination of high strength tubing and billet aluminum cross shafts make these arms amount to the lightest on the market with improved strength and durability. Robotically welded and high-quality powder coated these street control arms look great. 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.
