QA1 Heavy-Duty Upper Adjustable Trailing Arms for Select 1973-1988 GM A-Body and G-Body (Pair) - 5247

Fits select 1973-1988 Buick Century/Regal, Chevrolet Chevelle/El Camino/Malibu/Monte Carlo, GMC Caballero/Sprint, Oldsmobile Cutlass, and Pontiac Bonneville/Grand Prix/LeMans models.

QA1 Heavy-Duty Adjustable Trailing Arms (MPN 5247) provide the precise adjustability required for optimum handling and traction on classic GM A-Body and G-Body platforms. These arms allow for effortless wheelbase and pinion angle adjustments while installed on the vehicle—simply loosen the jam nuts to tune your suspension geometry. By replacing soft OE differential bushings with high-durometer polyurethane and utilizing a spherical rod end assembly on the chassis end, these arms eliminate bushing bind and allow the rear suspension to move more freely through its travel.

• Precision Tuning: Adjust pinion angle and wheelbase without removing the arms from the vehicle.
• Premium Construction: Zinc-plated and anodized finish for superior corrosion resistance and longevity.
• Advanced Articulation: Spherical ball or rod end assemblies with UHMW polyethylene bushings on the chassis end eliminate binding.
• Improved Traction: Keeps tires planted firmly for more predictable handling and better control.
• Direct Fit: Easy bolt-in installation replaces factory stamped steel arms; includes polyurethane differential bushings.
• Made in the USA: Manufactured to strict tolerances for high-performance street and track use.

Each set is sold as a pair and includes all necessary hardware for a complete upgrade from factory rubber bushings to a high-performance spherical and polyurethane setup.
