Rear Shock Absorber for 1987-1991 Chevrolet Blazer & More - KYB KG5415

Help keep the rear of your hard-working truck under control with the KYB shock absorber KG5415, a high-pressure monotube gas shock from KYB's Gas-a-Just line, with components and valving designed specifically for GM trucks. It fits many vehicles, among them the 1987-1991 Chevrolet Blazer, 1989-1991 Chevrolet R1500 Suburban and 1989-1991 Chevrolet R2500 Suburban, as a direct-fit rear shock for the listed applications. See the "Vehicles it fits" section for the full list.

• Monotube design: The gas and oil sit in two separate working chambers. An air-free hydraulic piston and valve area provides responsiveness and control, and a high-pressure nitrogen gas area with a floating piston is designed for fade-free operation and instant response.
• Extra damping: Adds up to 25% more damping performance over original equipment shocks, intended for vehicles that work, tow, or run larger, heavier tires and wheels.
• Triple chrome-plated piston rod: Fluid leaking can be a cause of shock failure, so the ultra-smooth rod finish is designed to reduce seal wear.
• Quick response: Its higher gas pressure responds quickly to help improve steering response.

This KYB gas shock absorber is designed to adjust automatically to your performance needs. Its floating-piston gas chamber provides a comfortable ride during normal driving and adds performance on demand. Signs a rear shock may need replacing include fluid on the shock body, excessive bouncing after bumps, and a floaty or unsettled rear end. Replacing both rear shocks together is recommended for even damping from side to side.
