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

If you're working on a 1964-1967 GM A-Body, like a Chevelle, GTO, or Skylark, and want to dial in your rear suspension, this set of UMI Performance Double Adjustable Upper and Lower Control Arms is a solid choice. These arms let you precisely adjust your rear end's pinion angle and overall alignment, which is crucial for getting the most out of your car, especially if you've modified the drivetrain or are looking for better handling.

This kit includes both the lower control arms, which feature spherical rod ends for smooth, bind-free movement, and the UMI Performance "Ultimate Arms" upper control arms. The double adjustability means you can make changes on the fly to fine-tune your setup. They're built with strong materials and designed to replace your stock arms, giving you more control over your vehicle's geometry. This is especially helpful when dealing with different rear end setups or when lowering your vehicle, as it allows you to correct alignment issues that can arise.

When installing these, you'll want to have a good understanding of suspension alignment. Having a way to measure pinion angle and overall alignment will be key to taking full advantage of the adjustability these arms offer. This kit is designed to be a direct replacement for your factory control arms, making the installation process as straightforward as possible, assuming you have the basic tools and knowledge for suspension work.
