KYB 565058 Shock Absorber - Front

KYB MonoMax Front Shock for Toyota Trucks

The KYB MonoMax 565058 is a heavy-duty front suspension shock absorber built for Toyota trucks that carry loads, tow, or see off-road use. Its monotube construction and large-bore design are aimed at improving control and stability on vehicles with a higher center of gravity.

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 demanding conditions
• Rubber dust boot helps protect the shaft and seal area from dirt and debris
• Engineered to work with electronic safety systems such as ESC and ABS
• Front suspension application for standard non-lifted Toyota truck setups

Product Details

KYB MonoMax shocks are part of the MonoMax line, a truck-focused product range built for heavier-duty use than a typical replacement shock. The KYB 565058 uses a monotube layout to help maintain fade-resistant performance under repeated compression and rebound cycles. With a compressed length of 9.45 inches, extended length of 13.15 inches, and 3.7 inches of stroke, this shock is sized for the listed front applications on Toyota T100, Toyota 4Runner, and Toyota Pickup models.

This part cross-references Monroe Shocks & Struts (e.g., 37030) for the same application.

What It Helps Address

• Excessive front-end bounce on Toyota T100, 4Runner, and Pickup trucks
• Reduced control when towing or hauling heavier loads
• Shock fade during repeated rough-road or off-road driving
• Premature wear from dirt and debris reaching the shaft seals
• Handling instability on higher center-of-gravity truck platforms

Installation Notes

• Fits 1993-1998 Toyota T100, front
• Fits 1986-1995 Toyota 4Runner, front
• Fits 1986-1995 Toyota Pickup, front
• Verify mount types before installation: lower mount E2(16X38), upper mount S1
• Confirm the vehicle is a standard non-lifted suspension application before ordering

Quality Assurance

KYB builds the MonoMax line for truck-duty use with a zinc-coated steel piston ring and an included dust boot to support durability in harsh conditions. The 565058 is part of KYB’s heavy-duty shock absorber lineup for Toyota truck front suspension service.
