KYB 565087 Shock Absorber - Rear

KYB MonoMax Rear Shock for Lifted GM Trucks

The KYB MonoMax 565087 is a heavy-duty rear shock absorber built for lifted Chevrolet and GMC trucks and SUVs that carry weight, tow, or see rough roads. Its monotube design, large bore construction, and off-road dust boot support stable handling and consistent damping in demanding use.

MonoMax Product Line Details

KYB MonoMax shocks are built for trucks that need firmer control than a standard replacement shock can provide. This line focuses on load stability, fade-resistant performance, and durability for lifted GM applications such as Chevrolet K1500, K2500, K3500, Tahoe, Blazer, and GMC K-series and Yukon models.

Key Features

• Up to 40% more damping performance than standard shock absorbers
• Monotube truck shock design for improved handling and control
• Zinc-coated stainless steel piston ring for a positive seal in severe conditions
• Rubber dust boot helps keep dirt and debris away from the shaft and seals
• Engineered to work with vehicles equipped with ESC, ABS, and related safety systems
• Rear shock absorber for lifted GM truck and SUV applications

Detailed Description

KYB MonoMax part number 565087 is a suspension shock absorber made for rear lift-replacement applications on 1988-1999 Chevrolet K1500, K2500, and K3500; 1992-1999 Chevrolet K1500 Suburban and K2500 Suburban; 1995-1999 Chevrolet Tahoe; 1992-1994 Chevrolet Blazer; 1988-1999 GMC K1500, K2500, and K3500; and 1992-1999 GMC Yukon. It is commonly used on 4-6 inch lifted GM trucks and SUVs where added control is needed for towing, hauling, and off-road driving. The 16.57-inch compressed length, 26.22-inch extended length, and 9.65-inch stroke support the intended rear suspension travel range.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Uses

• Rear-end bounce or instability on lifted Chevrolet K1500 and GMC K1500 trucks
• Excessive body movement when towing or hauling heavy loads
• Reduced control on rough pavement, gravel, or off-road terrain
• Need for a firmer rear shock on Chevrolet Tahoe, Blazer, or GMC Yukon applications
• Replacement for worn lift-specific rear shocks on GM 4x4 platforms

Installation Notes and Tips

Verify rear fitment by year, make, model, and lift height before installation. Confirm the lower mount type E2(14.6X41) and upper mount type E3(61.6X87X0) match the vehicle’s suspension hardware. Check shock length against the suspension travel available on the lifted rear axle to avoid topping out or over-compression.

Quality Assurance

KYB builds the MonoMax line for demanding truck use with a monotube construction, fade-resistant damping, and corrosion-resistant sealing components. The included dust cover adds protection for the shaft and seals in harsh driving conditions.
