Trailing Arms-Control Arms
Shop rear trailing arms and control arms for classic cars and trucks, including tubular, adjustable, upper, and lower configurations. Find vehicle-specific components and supporting hardware for Chevy C10 trucks, GM A-Body and G-Body cars, Impala, Camaro, Firebird, and other applications.
Rear Control Arms and Trailing Arm Components
Rear suspension geometry is shaped as much by where the arms attach as by the arms themselves. That is especially clear on C10 trucks, where tubular trailing arms, axle seats, crossmembers, and anti-squat brackets can all change how the axle is located and how the suspension reacts under load.
GM passenger cars approach the same job differently. Chevelle and A-Body applications use adjustable upper arms, billet lower arms, 4-link components, and Johnny Joint hardware, while full-size Impala and Biscayne setups pair rear upper arms with Panhard bars in several year-specific configurations.
Later G-Body and Camaro/Firebird applications add their own upper, lower, and complete arm sets, showing how rear axle control changes from one chassis design to another.
Rather than being a collection of similar-looking arms, this page covers the different links, brackets, and mounting structures that determine how the rear axle moves beneath each vehicle.
FAQ
What is the difference between front and rear control arms?
Both help locate suspension components, but they work within different suspension layouts. This collection is specifically dedicated to rear trailing arms and control arms, while POL maintains a separate Tubular Control Arms category for front suspension applications.
Are tubular trailing arms available for Chevy C10 trucks?
Yes. POL carries a tubular trailing arm set for 1960-72 Chevy C10 trucks. The collection also includes related axle seats, mounting hardware, crossmembers, and anti-squat brackets, allowing buyers to address other parts of the trailing-arm mounting system when required.
What do anti-squat brackets do in a C10 trailing-arm suspension?
Anti-squat brackets change the mounting position and geometry of the trailing-arm arrangement. POL carries 1963-72 C10/C15 anti-squat brackets along with a separate version intended for trucks using a drop crossmember. Match the brackets to the crossmember and rear suspension configuration installed on the truck.
Are adjustable rear control arms available for Chevy Chevelle and GM A-Body cars?
Yes. The collection includes adjustable rear upper control arm sets for 1964-67 and 1968-72 Chevelle and GM A-Body applications. Billet aluminum rear lower control arms are also available for 1964-72 GM A-Body cars.
Can I buy rear control arms for a classic Chevy Impala separately?
Yes. Individual rear upper control arms are listed for several Impala and Biscayne generations, including 1958, 1959-64, 1965-66, and 1967-70. Some applications also have combined upper control arm and Panhard bar kits.
What rear control arms are available for 1978-88 GM G-Body cars?
POL offers three main choices: an adjustable rear upper control arm set, a rear lower control arm set, and a combined upper-and-lower set. This lets buyers address one part of the rear suspension or replace the upper and lower arms together.
What should I check before ordering rear trailing arms or control arms?
Confirm the exact vehicle and year, then identify the rear suspension and axle currently installed. Check whether you need upper arms, lower arms, or trailing arms, and inspect the mounting points, crossmember, bushings, ride height, and related locating components. Modified suspension or chassis mounting points can affect which components fit correctly.
