Hotchkis Performance 1203AA Double Adjustable Upper Trailing Arms GM A-Body - 1964-1967

The Hotchkis Performance Double Adjustable Upper Trailing Arms are engineered to dramatically improve traction and handling on 1964-1967 GM A-Body vehicles. These precision-built control arms feature dual adjustment points that allow for easy pinion angle tuning, reducing driveline vibration while maximizing rear wheel traction under acceleration.

Key Features:

• Double adjustable design for precise pinion angle adjustment
• Exclusive Swivel-Max bushings provide non-binding articulation throughout suspension travel
• Improves rear suspension efficiency and traction, especially under hard acceleration
• Durable construction with gloss black powder coat finish and clear anodized components
• Essential upgrade for high horsepower applications
• Direct bolt-on replacement for factory upper trailing arms

The Swivel-Max bushing technology eliminates binding that occurs with traditional bushings during suspension movement, allowing the rear axle to move freely while maintaining proper geometry. This translates to improved grip, reduced wheel hop, and better power transfer to the pavement. The adjustable design also makes it easy to correct pinion angle after lowering or when running different ride heights.

Sold as a pair for both driver and passenger sides. Ideal for street performance, drag racing, and autocross applications on GM A-Body platform vehicles including Chevelle, GTO, Cutlass, and Skylark models.
