Product Description

The Pedders PED-7843 Rear Heavy Duty Lifted Coil Spring is a robust suspension component designed specifically for 2004-2006 Pontiac GTO models with rear-wheel drive. This heavy duty spring restores or increases rear ride height while strengthening load support over worn stock springs, making it ideal for vehicles carrying additional weight or seeking improved rear stance. Engineered to strict ISO 9001 standards, the spring undergoes hot forming, oil quenched tempering, and shot peening to deliver reliable strength and consistent performance over time.

Installation of the PED-7843 spring helps maintain chassis balance when the vehicle is loaded or used in performance driving, reducing excessive rear sag and improving handling consistency. The powder-coated finish enhances corrosion resistance, helping the spring last through years of service. Sold individually, two springs are needed for a complete rear suspension renewal. Professional installation and a post-suspension alignment check are recommended for best results.
