This replacement shock absorber (OEM #728639) is designed to enhance your vehicle's performance. With a nitrogen gas charged shock, it minimizes hydraulic fluid aeration for a more responsive ride. Specially designed concave bushings keep the bushing in place and prevent bushing walk out, while precision robotic welded eye rings provide superior durability. The reinforced seal and gas charged design ensure long-lasting performance, even in extreme temperatures. The mirror finished hard chrome OE style piston rod offers corrosion resistance and leak-free sealing. With reinforced eye rings, this shock absorber is built to handle the toughest road conditions. Sold individually, it fits OEM #728639 and has crossover part numbers for Monroe (65104) and Gabriel (85026).
