UMI Performance 64-67 GM A-Body Double Adjustable Upper & Lower Rear Control Arms

These double adjustable rear control arms from UMI Performance are built with strong, 1.25-inch diameter DOM tubing, a common choice for performance suspension components because it offers a good balance of strength and weight. This complete kit includes both the upper and lower control arms, specifically designed for 1964-1967 GM A-Body vehicles like the Chevrolet Chevelle, Pontiac GTO, and Buick Skylark. The double adjustability means you can fine-tune your rear suspension alignment, which is crucial for getting the handling characteristics you want, whether you're aiming for better traction off the line or more stable cornering.

The lower control arms feature high-quality spherical rod ends, which allow for smooth, bind-free movement and precise adjustments. The upper control arms, referred to as 'Ultimate Arms' by UMI, are also fully adjustable. This level of adjustability lets you dial in your pinion angle and caster/camber settings more accurately than with stock or single-adjustable arms. This is especially important if you've modified your vehicle's ride height or are looking to optimize its performance for spirited driving or track use. The robust construction ensures these arms can handle the demands of a performance-oriented vehicle.

When installing these, you'll want to ensure you have the necessary tools for suspension work. Proper alignment after installation is critical to realize the full benefits of these adjustable arms. This kit is designed to be a direct replacement for your factory control arms, simplifying the installation process. Getting your rear suspension dialed in with these arms can make a notable difference in how your classic GM A-Body handles.
