KYB 565090 Shock Absorber - Front

KYB MonoMax Front Shock for Lifted Ford Trucks

The KYB MonoMax 565090 is a heavy-duty front shock absorber built for lifted Ford Super Duty trucks that need added control under load. Its monotube design and large-bore construction support stable handling on rough roads, towing routes, and jobsite use.

MonoMax Performance Details

KYB’s MonoMax line is focused on truck applications that see demanding service. This shock uses a monotube layout for consistent damping, and the zinc-coated stainless steel piston ring helps maintain a positive seal in severe conditions. A rubber dust boot is included to help shield the shaft and seals from dirt and debris.

• Up to 40% more damping performance than standard shock absorbers
• Front lift replacement shock for lifted Ford F-250 Super Duty and Ford F-350 Super Duty applications
• Truck-specific monotube design for improved control and response
• Zinc-coated stainless steel piston ring for sealing in harsh conditions
• Dust boot included to help protect against road grime and off-road debris
• Engineered to support vehicles with electronic safety systems such as ESC and ABS

Detailed Application Overview

Part number 565090 is intended for 1999-2004 Ford F-250 Super Duty and 1999-2004 Ford F-350 Super Duty front lift replacement applications with 2.5 to 4 inches of lift. It cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. For buyers searching for a Ford F-250 Super Duty front shock or a Ford F-350 Super Duty lifted suspension shock, the KYB MonoMax 565090 provides a direct heavy-duty option built around load control and durability.

Common Problems This Shock Can Address

• Excessive front-end bounce after installing a lift kit
• Reduced stability when towing or hauling heavy loads
• Harsh control loss on rough pavement or off-road surfaces
• Premature wear from dirt, debris, and moisture exposure
• Inconsistent damping in demanding truck use
