What Is a Suspension Trailing Arm?
The trailing arm is one of the most fundamental links in a vehicle's rear suspension system. A trailing arm connects the rear axle or wheel hub to the chassis, with its pivot point positioned forward of the wheel center. Because the axle "trails" behind that pivot, the arm controls longitudinal forces — keeping the rear wheels properly located during acceleration, braking, and cornering. Without a functioning trailing arm, the rear suspension simply cannot do its job.
Trailing arms are typically used on the rear axle or wheels of a vehicle, and they are found on everything from compact front-wheel-drive cars to performance muscle cars and light trucks. In some designs — particularly semi-trailing arm setups — the arm also influences camber behavior and toe angle, making it a critical component for alignment and predictable handling.
Why Trailing Arms Matter for Handling and Safety
The trailing arm's primary role is to resist the fore-and-aft movement of the axle under load. When you accelerate, the rear axle wants to push forward; when you brake hard, it wants to lag behind. The trailing arm acts as a rigid anchor, keeping the axle in its proper place while still allowing the wheel to travel up and down over bumps and road imperfections.
A worn or damaged trailing arm — or its associated bushings — can cause a host of serious problems. Common warning signs include uneven or accelerated rear tire wear, clunking noises over bumps, the vehicle "dog-tracking" (rear wheels not following front wheels in a straight line), or the car pulling to one side. Because the trailing arm is located underneath the rear of the vehicle, it is especially vulnerable to road debris, rust, and impacts from curbs or potholes.
Trailing arm bushings — the rubber or polyurethane isolators at the pivot points — often wear before the arm itself does. Replacing bushings promptly is key: worn bushings allow the arm to flex under load, which can lead to wheel hop, inconsistent launch behavior, and accelerated arm wear over time.
Choosing the Right Trailing Arm
When shopping for a replacement or performance trailing arm, consider three main factors: material (steel for durability and affordability; aluminum for weight savings in high-performance builds), bushing type (rubber for OE-level ride quality; polyurethane for performance; spherical bearings for maximum rigidity in race applications), and adjustability (fixed-length arms restore factory geometry, while adjustable arms allow fine-tuning of suspension geometry for lowered or track-prepared vehicles).
Top Trailing Arm Brands
For drivers seeking a factory-correct restoration, Genuine parts deliver OEM-spec fit and finish, ensuring that your suspension geometry returns exactly to manufacturer specifications with no guesswork on compatibility.
For enthusiasts chasing better performance on the street or strip, BMR Suspension is a trusted name in high-performance suspension and chassis components, offering trailing arms engineered for American muscle platforms like the Chevrolet Camaro, Pontiac G8, and more. Their lineup spans polyurethane-bushed non-adjustable arms for street/drag use to full spherical-bearing units built for serious race abuse.
