The Bilstein B8 5125 Monotube Shocks Set is a high-performance suspension component designed for 4WD vehicles requiring a 2-2.5 inch lift. Constructed with high gas pressure monotube technology, these shocks feature a 46mm piston with self-adjusting deflective disc valving, ensuring consistent damping and improved ride quality. The shocks are extended length to accommodate lift systems and are equipped with industry-standard 5/8 inch hourglass bushings. The set includes all necessary hardware such as washers, bushings, and nuts, allowing for a straightforward installation process that reuses factory shock mounting bolts. Backed by a 90-day manufacturer warranty, these shocks are built for durability, performance, and custom applications, making them suitable for off-road and lifted vehicle use.
Designed specifically for 1973-1987 GMC K15 4WD models with a 2-2.5 inch lift, this set is a direct replacement for factory shocks and ideal for off-road, towing, or lifted daily drivers. The package contains two front and two rear shocks, tailored for vehicles with extended lift systems. These shocks are compatible exclusively with 4WD configurations and are intended for custom suspension setups where direct fitment may not be available. Installation involves reusing factory hardware, making them a practical upgrade for off-road enthusiasts and suspension builders seeking enhanced damping and stability on lifted GMC K15 trucks.
