QA1 64-77 GM A-Body Lower Adjustable Tubular Trailing Arms

If you're working on the rear suspension of your classic GM A-Body, especially for a performance build or when fitting larger wheels and tires, these lower adjustable tubular trailing arms from QA1 are a solid choice. They're designed to replace the stock arms and give you the adjustability needed to dial in your suspension geometry. Getting the alignment just right is key to how your car handles and how your tires wear, and these arms make that process much more straightforward.

These trailing arms are built from strong tubular steel and are proudly made in the USA. The adjustable design allows you to fine-tune the pinion angle and wheelbase, which is especially helpful if you're running a different rear end or want to optimize your setup for drag racing or road course use. Installation is designed to be a simple bolt-in process, meaning you won't need to cut or weld anything to get them fitted. This makes for a cleaner build and saves you time in the shop.

This part fits a wide range of GM A-Body vehicles from 1964 through 1977, including popular models like the Chevrolet Chevelle, Pontiac GTO, and Oldsmobile Cutlass. Having the ability to adjust your trailing arms means you can achieve perfect wheel and tire fitment, preventing rubbing and ensuring your car looks and performs its best. It's a worthwhile upgrade for anyone serious about their classic GM's handling and stance.
