• Up to 40% more damping performance than standard shock absorbers
• Large-bore design for added control on higher center-of-gravity vehicles
• Zinc-coated stainless steel piston ring for a positive seal in severe conditions
• Off-road dust boot included to help protect the shaft and seals
• Engineered to work with vehicles equipped with electronic safety systems such as ESC and ABS
• Lower mount type E1 and upper mount type E1

Product Details

KYB MonoMax is the truck-focused line within KYB’s shock absorber range, built for drivers who use their vehicle for work, hauling, or off-pavement driving. Part number 565057 uses a monotube construction that helps maintain consistent damping as conditions change, while the included dust boot and corrosion-resistant piston ring support durability in demanding environments. This rear shock is a direct fit for 1986-1994 Nissan D21 rear and 1995-1997 Nissan Pickup rear applications. This part cross-references Gabriel 77907 for the same application.

Common Problems This Shock Can Address

• Excessive rear-end bounce over uneven pavement
• Reduced control when towing or carrying heavy loads
• Soft or worn factory shock performance
• Rear suspension instability on rough roads
• Loss of damping consistency during extended use

Installation Notes

Verify compressed length 12.72 in., extended length 19.41 in., and stroke length 6.69 in. before installation. Confirm E1 upper and lower mounts match the vehicle’s original mounting style, and inspect surrounding suspension components for wear before replacing the shock. For best results, install on the rear position specified for the vehicle and torque fasteners to factory service specifications.
