Upgrade your 2004–2006 Pontiac GTO's suspension with the Pedders SportsRyder and Heavy Duty Spring lineup, engineered to meet the needs of daily drivers, street performance enthusiasts, and drag racers alike. Whether you're looking to achieve a more aggressive lowered stance, retain factory ride height with improved handling, increase rear load capacity, or maximize traction at the drag strip, Pedders offers a spring solution designed for your application.

The SportsRyder Lowering Spring Kit lowers the vehicle to improve handling, reduce body roll, and provide a sportier appearance without sacrificing everyday comfort. For those who prefer factory ride height, the SportsRyder Stock Height Spring Kit delivers enhanced suspension performance and improved vehicle control while maintaining the original stance.

For high-performance or heavy-load applications, the Heavy Duty Rear Springs feature an increased spring rate to reduce rear-end squat, improve stability, and better support additional vehicle weight. Enthusiasts focused on straight-line performance can opt for the X-Drag Heavy Duty Rear Springs, specifically engineered to optimize weight transfer during hard launches for improved traction and consistent drag strip performance.

Manufactured from premium spring steel and designed to Pedders' exacting standards, each spring option offers exceptional durability, precise fitment, and long-lasting performance. No matter your driving style or performance goals, there's a Pedders spring configuration to help your Pontiac GTO perform at its best.
