This replacement shock absorber, OEM #3606859C1, is designed for heavy-duty applications and provides long-lasting, dependable performance even under the worst temperature conditions. The nitrogen gas-charged shock minimizes hydraulic fluid aeration for a more responsive performance, while specially designed concave bushings keep the bushing in place and prevent bushing walkout. Precision robotic welded eye rings provide superior durability, and reinforced eye rings are designed to handle even the worst road conditions. With a mirror-finished hard chrome OE style piston rod that provides superior corrosion resistance and leak-free sealing, this shock absorber is sold individually and fits OEM #3606859C1, Monroe crossover part number 65157, 65158, and Gabriel crossover part number 85954.
