Fitment Notes

• Front sway bar for GM B-Body applications with vehicle-specific tubular geometry.
• All verified applications use rear-wheel drive (RWD).
• The sway bar is chassis-specific rather than engine-specific; it is compatible across the applicable factory engine configurations listed for the B-Body platform.
• Designed for GM B-Body vehicles from 1978 through 1996; exact body style and factory mounting configuration must match.
• Includes greaseable polyurethane bushings and plated mounting hardware.
• 1997 and newer GM B-Body applications are excluded.
• No 2026 application is applicable because the supported GM B-Body platforms ended before 2026.

Features

• Performance-tuned front sway bar designed specifically for GM B-Body vehicles.
• 1-3/8-inch diameter provides increased torsional stiffness for improved chassis control.
• Hollow construction reduces weight while maintaining high sway-bar stiffness.
• 4130 chromoly steel construction provides high strength and durability.
• 3/16-inch wall tubing provides the specified lightweight tubular construction.
• Application-specific geometry is engineered for the GM B-Body chassis.
• Helps reduce body roll during cornering and hard acceleration.
• Improves handling stability and steering response.
• Helps maintain more consistent tire contact during cornering.
• CNC-bent tubing provides precise application-specific geometry.
• Machined and welded bar ends provide durable mounting points.
• Gloss black powder-coated finish provides corrosion resistance.
• Greaseable polyurethane bushings provide controlled sway-bar movement.
• Plated mounting hardware is included.
• Designed for bolt-on installation using factory sway-bar mounting locations where applicable.
• Made in the USA.

Product Description

QA1 52862 is a performance-tuned front sway bar designed for 1978-1996 GM B-Body vehicles. The 1-3/8-inch hollow 4130 chromoly bar is engineered to increase chassis roll resistance while avoiding the weight penalty of a comparable solid bar. Its application-specific geometry helps reduce body roll, improve cornering stability, and maintain more consistent tire contact during performance driving.

The sway bar uses CNC-bent tubing, machined and welded bar ends, and a durable gloss black powder-coated finish. The 3/16-inch-wall tubular construction provides a strong and lightweight assembly, while greaseable graphite polyurethane bushings provide controlled movement at the chassis mounting points. QA1 supplies plated mounting hardware and designs the bar for bolt-on installation using factory sway-bar mounting locations where applicable.

QA1 52862 covers the applicable GM B-Body platforms from 1978 through 1996, including Chevrolet, Buick, Oldsmobile, and Pontiac applications. The verified application data includes Caprice, Impala, Impala SS, Bel Air, Roadmaster, LeSabre, Custom Cruiser, Delta 88, Bonneville, Catalina, Parisienne, Safari, and related B-Body configurations. Because this is a chassis-specific sway bar rather than an engine-specific component, factory engine variations within the verified B-Body applications do not change the sway-bar application.
