The KYB MonoMax 565001 is a heavy-duty monotube shock absorber built for trucks that carry weight, tow, or see rough road use. It is engineered for front suspension applications on select Ford, Mazda, and Bronco II models, with a focus on control, stability, and consistent damping.

• Monotube truck shock design for improved handling response
• Up to 40% more damping performance than standard shock absorbers
• Zinc-coated stainless steel piston ring for a positive seal in demanding conditions
• Rubber dust boot helps keep dirt and debris away from the shaft and seals
• Built to work with vehicles equipped with electronic safety systems such as ESC and ABS
• Front suspension application for select Ford Ranger, Ford Explorer, Mazda Navajo, and Ford Bronco II models

MonoMax Product Line Details

KYB MonoMax shocks are part of KYB’s truck-focused suspension line. The design uses a large-bore monotube layout to deliver firmer control and fade-resistant performance under load, making it a practical choice for vehicles that regularly tow, haul, or operate off pavement. Part number 565001 is specified for front use on select applications and is built around durability-focused hardware and sealing components.

This part cross-references Monroe Shocks & Struts (e.g., 37015) for the same application.

Installation Notes

Verify compressed length, extended length, and stroke length against the existing front shock before installation. This KYB 565001 uses lower mount type E1 and upper mount type S1, so confirm mount style and vehicle configuration before ordering. Check for clearance around the dust boot and inspect related suspension components for wear while the shock is removed.

Quality Assurance

KYB builds the MonoMax line as a heavy-duty monotube shock absorber with a zinc-coated piston ring and protective dust boot for demanding service. The design is intended to maintain consistent damping performance under changing road and load conditions.
