Lower Trailing Arm Metric G-Body

The ALLSTAR PERFORMANCE Lower Trailing Arm Metric G-Body is a purpose-built rear suspension component engineered for GM G-Body platform vehicles manufactured between 1978 and 1988. This lower trailing arm replaces worn or damaged factory components and restores proper rear axle geometry and wheel alignment characteristics critical to vehicle handling and tire wear patterns.

Constructed from steel with a c-channel profile and finished in durable black paint, this trailing arm withstands the loads and stresses inherent to rear suspension duty. The metric specification confirms compatibility with the G-Body chassis dimensioning standard. At 4.15 pounds and measuring 24.5 inches in length, the component integrates directly into the existing suspension architecture without modification. Proper trailing arm condition is essential for maintaining vehicle stability during cornering, braking, and acceleration—worn arms introduce deflection that degrades handling response and increases uneven tire consumption.

This trailing arm is suited for restoration work, suspension rebuilds, and repair applications on classic and vintage G-Body vehicles including Chevrolet Malibu, Pontiac Grand Am, Oldsmobile Cutlass, and Buick Regal models. Whether addressing suspension wear discovered during inspection or executing a complete rear suspension overhaul, this ALLSTAR PERFORMANCE component provides the structural integrity and dimensional accuracy required for proper alignment and safe handling characteristics. Installation should be paired with inspection of related suspension bushings and mounting points to ensure complete system performance.
