Product Details

KYB MonoMax is the brand’s truck-focused shock line, built for heavier, higher-center-of-gravity vehicles that need more control than a standard replacement shock can provide. Part number 565059 uses a monotube construction that helps maintain fade-resistant performance during repeated compression and rebound cycles. For Toyota truck owners, this shock is a direct upgrade path for suspension performance on the rear of the 1990-1995 Toyota 4Runner and the front of the 1981-1990 Toyota Land Cruiser. This part cross-references Gabriel 77726 for the same application.

Common Problems This Shock Can Address

• Excessive body motion on rough pavement or uneven roads
• Reduced control when towing a trailer or hauling heavy loads
• Shock fade during repeated suspension movement
• Premature wear from dirt and debris around the shaft seal
• Loose or unsettled ride feel on truck and SUV applications

Installation Notes and Tips

Verify mount style, compressed length, and extended length before installation. This KYB 565059 shock uses specific upper and lower mount types, so confirm the vehicle position and suspension configuration against the fitment listing before ordering. Inspect related suspension components, bushings, and mounting points during replacement to help restore proper ride control.

Quality Assurance

KYB builds the MonoMax line for demanding truck service, with a monotube design and corrosion-resistant piston ring intended for consistent operation in severe conditions. Confirm fitment for your Toyota 4Runner or Toyota Land Cruiser by year and position before installation.
