Upper Trailing Arm Metric G-Body

The Upper Trailing Arm Metric G-Body is a critical rear suspension component engineered for GM G-Body vehicles manufactured between 1978 and 1988. Designed to support the lateral and vertical loads transmitted through the rear axle assembly, this trailing arm maintains wheel alignment and controls rear-end movement during acceleration, braking, and cornering. Whether you're restoring a classic Chevrolet Malibu, Pontiac Grand Prix, or Oldsmobile Cutlass, or upgrading a street machine's suspension geometry, the Upper Trailing Arm Metric G-Body restores OEM handling characteristics and ensures safe, predictable vehicle dynamics.

This component features a welded C-channel steel construction finished in durable black paint, providing strength and corrosion resistance necessary for rear suspension duty. The metric specifications ensure precise fitment to G-Body rear suspension geometry, maintaining correct wheelbase and pinion angle for optimal driveline performance. At 2.45 pounds and measuring 19 inches in length, the Upper Trailing Arm integrates seamlessly into factory and modern suspension architectures. Steel construction absorbs impact loads while the painted finish protects against rust and weathering, extending component service life in both street and track environments.

Professional restoration shops, weekend enthusiasts, and high-performance builders rely on OEM-specification trailing arms to maintain suspension integrity and vehicle safety. Installation requires proper alignment equipment to ensure rear-axle tracking and minimize tire wear after fitment. This trailing arm is sold individually, so verify whether your G-Body requires single or dual replacement based on suspension inspection and condition assessment. Allstar Performance's manufacturing standards ensure compatibility with both factory rear-end housings and modern performance upgrades, making this component essential for comprehensive G-Body suspension restoration or modernization projects.
