This pair of front strut assemblies with coil springs is engineered as a direct replacement for 20042008 Pontiac Grand Prix models equipped with 16, 17, or 18-inch wheels. Each unit integrates a thicker strut pipe and heavier spring to provide robust structural intensity and precise suspension control. The damper is filled with Japanese ENEOS brand damping oil, rigorously tested for viscosity, density, and high- and low-temperature performance to ensure stable operation from -40C to 80C. Every batch undergoes 3,000,000 fatigue durability tests with no oil leakage and minimal damping force decay. The coil spring has been subjected to over 600,000 continuous fatigue cycles to confirm high tensile strength and long-term resilience. Extension and compression lengths match original factory specifications, preserving full stroke and consistent ride quality. Sold as a pair for the front left and right positions, the assemblies arrive pre-assembled for straightforward installation without the need for spring compression tools. Product dimensions are 27.36 x 13.19 x 8.66 inches and total package weight is 47.62 lb.
