Lower Trailing Arms - 78-96 B-Body OEM Length

The Lower Trailing Arms for 78-96 B-Body OEM Length by QA1 (SKU QA15203) are engineered replacement suspension components designed for Chevrolet and Pontiac B-Body platforms including Chevelle, Malibu, and Grand Am models. These trailing arms serve as critical load-bearing members in the rear suspension geometry, controlling axle housing movement and maintaining alignment under cornering, braking, and acceleration loads. Proper trailing arm condition is essential for vehicle stability, tire wear consistency, and handling predictability—making this OEM-length pair an ideal choice for restoration, repair, or performance-focused builds on classic American muscle and mid-size vehicles.

These tubular steel trailing arms feature a black powder-coat finish that resists corrosion and provides a factory-correct appearance. Each arm incorporates greasable polyurethane bushings at the chassis pickup points, allowing controlled articulation while reducing compliance noise and improving steering response compared to worn rubber isolators. The tubular construction provides excellent strength-to-weight ratio while maintaining OEM dimensions for drop-in compatibility; the pair weighs 19.3 lbs and measures 26 inches in length, ensuring zero modification to factory mounting locations or suspension geometry. The polyurethane bushings are serviceable, permitting extended maintenance intervals and the ability to dial in suspension feel through bushing durometer selection without replacing the entire arm assembly.

These Lower Trailing Arms are ideal for restorers seeking OEM-correct replacement parts, enthusiasts upgrading worn suspension, and builders preparing B-Body platforms for street or strip duty. Installation requires basic hand tools and jack support; no welding or fabrication is necessary due to OEM-length design. The greasable bushing design benefits drivers who perform regular maintenance and value tunable suspension response, while the powder-coated steel construction delivers durability across street, show, and light performance applications. Fitment is confirmed for 1978–1996 Chevrolet and Pontiac B-Body vehicles with rear drum or disc brakes and standard or lowered ride heights.
