QA1 64-72 GM A-Body Lower Boxed Trailing Arms

QA1 is known for making performance suspension and driveline components, and these boxed lower trailing arms are a solid choice for your 1964-1972 GM A-body or G-body vehicle. If you're looking to improve how your car handles, especially if you're doing a suspension upgrade or driveline work, these arms can make a real difference. They are built with .12-inch wall thickness steel for strength and feature greasable bushings, meaning you can keep them properly lubricated for a longer service life.

What's really handy about these trailing arms is that they are adjustable. This means you can easily fine-tune your vehicle's wheelbase and pinion angle, which is crucial for getting the alignment just right and ensuring your driveshaft is running true. They are designed as a direct fit, meaning installation is straightforward with a bolt-in process, no welding or cutting required. This makes them a popular option for builders who want to improve their car's stance and performance without a complicated install.
