What is the benefit of double adjustable trailing arms?

Double adjustable trailing arms allow you to precisely change the pinion angle of your rear differential while the suspension is installed on the vehicle. This is key for optimizing traction and reducing vibrations, especially with modified or high-horsepower applications.

What are Swivel-Max bushings and why are they important?

Swivel-Max bushings are a Hotchkis exclusive design that offers high articulation and easy lubrication. They allow the suspension to move freely without binding, which improves rear suspension efficiency and traction during dynamic driving conditions.

Do these trailing arms come with all necessary hardware for installation?

Yes, these trailing arms are a complete, ready-to-bolt-in package. They include the upper trailing arms themselves and polyurethane rear end housing bushings.

Product Details

If you're looking to get the most out of your 1964-1967 GM A-Body muscle car, these Double Adjustable Upper Trailing Arms from Hotchkis are a serious upgrade. They're designed to help you fine-tune your rear suspension for better traction and handling, especially if you've got a high-horsepower setup. This means less wheel hop and a more planted feel when you accelerate.

What sets these apart is the double adjustable design, which lets you make changes to the pinion angle right in the car. This is crucial for dialing in your setup, whether you're hitting the drag strip or just want improved performance on the street. The arms feature strong, TIG-welded steel construction for durability, paired with lightweight billet aluminum center sections. Hotchkis also uses their exclusive Swivel-Max bushings, which allow for smooth, non-binding articulation during suspension travel. This helps the suspension work more efficiently and reduces unwanted flex.

These trailing arms come complete with polyurethane rear end housing bushings and are ready to bolt in. They're a popular choice for models like the Chevelle, GTO, and El Camino, offering a significant improvement in how your classic muscle car handles and hooks up.
