Bilstein B6 4600 Series Rear 46mm Monotube Shock Absorber for 2004-2012 Chevrolet Colorado, GMC Canyon, and Isuzu i-Series (24-186209)

Fits select 2004-2012 Chevrolet Colorado, GMC Canyon, and Isuzu i-280, i-290, and i-370 trucks.

The Bilstein B6 4600 shock absorber is engineered as a direct-fit upgrade for stock-height light trucks and SUVs. Built to replace worn-out OE components, this rear shock uses a 46mm monotube design to provide consistent, fade-free performance even under heavy loads or varying road conditions. The monotube construction allows for rapid heat dissipation and greater durability compared to standard twin-tube shocks.

Each shock features a unique velocity-sensitive digressive piston that instantly reacts to road inputs, providing a firm, controlled ride without sacrificing comfort. These units are tuned specifically for the Colorado, Canyon, and i-Series platforms to ensure optimal damping and handling. Designed for ease of installation, these shocks bolt directly to factory mounting points and are compatible with OEM springs and hardware.
