Vehicle Fitment

• 1964-1972 Chevrolet Chevelle, Malibu, El Camino, Monte Carlo (GM A-Body)
• 1964-1972 Buick Skylark, Special, Century, GS, Sport Wagon (GM A-Body)

Fitment Notes

• Not compatible with OE-type coil springs - must be used with a coilover system (QA1 Pro Coil Systems recommended)
• Compatible with OE or drop spindles
• Mounts in OE location - no cutting, fabricating, or welding required
• A professional front-end alignment is required after installation due to changes in suspension geometry
• When used together with QA1 lower control arms, adds 3-4 degrees of caster and 0.5-1 degree of negative camber

Features

• Pro-Touring 2.0 Series - engineered for autocross, road course, and aggressive street and pro-touring driving
• Ultra low friction composite bushings eliminate bind for smooth, precise suspension movement and superior handling
• QA1 Ultimate Low-Friction Ball Joint - rebuildable, low-maintenance, with integrated dust boot for long-term service
• 1-inch taller ball joint stud increases negative camber gain to maximize tire contact patch during cornering
• Increased positive caster design improves straight-line stability and steering response
• High-strength low alloy steel with billet aluminum cross shafts - under 7 lbs. each for reduced unsprung weight
• Robotically welded construction for consistent strength and a clean, finished appearance
• Black powder coated finish for corrosion resistance and a professional look

Product Description

The QA1 52522 Pro-Touring 2.0 Front Upper Control Arms are purpose-built for autocross, road course, and pro-touring builds on 1964-1972 GM A-Body vehicles including the Chevelle, Malibu, El Camino, GTO, Cutlass, and related platforms. Manufactured from high-strength low alloy steel with billet aluminum cross shafts, each arm weighs under 7 lbs., significantly cutting unsprung weight compared to factory stamped steel arms for faster, more responsive suspension behavior. Ultra low friction composite bushings replace the rubber factory units to eliminate bind and allow the suspension to move freely through its full range of motion.

The QA1 Ultimate Low-Friction Ball Joint features an integrated dust boot and a 1-inch taller stud that increases negative camber gain during cornering - keeping the tire contact patch optimal for maximum grip. When paired with QA1 lower control arms, these uppers deliver 3-4 degrees of added caster and 0.5-1 degree of negative camber for measurably improved handling geometry. These arms bolt directly into the factory mounting location with no cutting or welding and accept OE or drop spindles. A professional front-end alignment is required after installation. Note that a coilover system is required - these arms are not compatible with OE-type coil springs.
