KYB 565068 Shock Absorber - Rear

KYB MonoMax Rear Shock Absorber

The KYB MonoMax 565068 is a heavy-duty rear suspension shock absorber built for trucks that carry weight, tow, or see rough road use. It is a monotube design that adds control and stability for Chevrolet Silverado 1500 Classic and GMC Sierra 1500 Classic applications, along with earlier GM truck fitments.

Key Features

• Monotube shock design for consistent damping and improved control
• Up to 40% more damping performance than standard shock absorbers
• Zinc-coated stainless steel piston ring for sealing in severe conditions
• Rubber dust boot helps protect the shaft and seal area from dirt and debris
• Large-bore construction for heavier, higher center-of-gravity trucks
• Rear position application for standard non-lifted suspensions where specified

Product Details

KYB MonoMax is part of the KYB MonoMax line, a truck-focused suspension shock absorber series built for demanding use. The 565068 uses a monotube layout that responds quickly to changing road conditions and helps maintain fade-resistant performance under load. With a compressed length of 16.14 inches, extended length of 25.39 inches, and 9.25 inches of stroke, this rear shock is sized for the listed GM truck applications. Lower and upper mounts are E2 (14.6 x 41), and the dust cover is included. This part cross-references Monroe Shocks & Struts 911504 for the same application.

What This Shock Helps Address

• Excessive rear-end bounce on rough pavement
• Reduced control when towing or hauling heavy loads
• Body movement in trucks with a higher center of gravity
• Fade in shock performance during extended use
• Worn rear shock response on older GM pickup suspensions
