With a 46mm digressive piston design, they react quickly to changing terrain, providing a smoother ride on rough pavement or uneven backroads. These shocks feature a 10.37-inch stroke and a durable 2-inch diameter zinc-plated body that resists corrosion and holds up well under harsh conditions. Designed for 2WD and 4WD GM 2500HD trucks from 2011–2021, they mount easily with eye-to-eye fittings and come with protective black boots to keep debris away from the shaft. The monotube design helps keep damping consistent, even during repeated impacts or long drives with a load in the back. With no reservoir or external adjustability, these are built to deliver dependable performance without the need for constant tinkering. Whether your truck sees job site duties or weekend trail runs, these shocks are tuned for the real-world conditions your truck faces daily.
