63-70 Gm Rr Track Arm Bushings Black

The 63–70 GM Rear Track Arm Bushings in Black represent a critical suspension component upgrade for classic GM B-Body vehicles from 1963–1973. These Panhard bar bushings combine polyurethane and steel construction to deliver superior compliance and vibration isolation compared to original rubber components that degrade over decades. Track arm bushings control lateral chassis movement during cornering and braking, making them essential for both handling precision and chassis longevity on the street or strip.

Hyper-Flex polyurethane formulation offers dramatically improved durability and responsiveness compared to aged OEM rubber. The steel collar reinforcement prevents binding and maintains consistent bushing geometry under load, which is critical when the suspension experiences aggressive cornering forces or sustained g-loads during performance driving. The black finish resists corrosion and integrates cleanly with modern restoration aesthetics. This kit format simplifies installation by grouping all necessary components, reducing fitment guesswork and labor time during a suspension rebuild or update.

These bushings appeal to classic car restorers, street rod builders, and enthusiasts upgrading worn factory suspension on Chevrolet, Pontiac, Oldsmobile, and Buick B-Body platforms. The rear Panhard bar location makes this component fundamental to rear-axle centering—proper bushing condition directly affects rear-end tracking, tire wear patterns, and overall chassis stability. For anyone addressing suspension play, excessive body roll, or preparing a classic for handling-focused driving, this upgrade addresses a common wear point that original rubber cannot reliably support long-term.

GM B-Body suspension geometry relies on precision bushing compliance to manage lateral loads without harshness—polyurethane formulations strike the balance between compliance and control that modern drivers expect from classic vehicles. Installation requires basic suspension work; verify fitment against your specific year and model before ordering. Part number 3.7110G ensures proper specification matching for 1963–1973 rear Panhard bar applications.
