Product Details

MonoMax is KYB’s truck-focused shock line, built for rear suspension service where load control and consistent damping matter. The KYB MonoMax 565033 uses a monotube layout that responds quickly to changing road conditions and maintains fade-resistant performance under repeated use. It is a strong choice for Chevrolet Express 1500 rear shock replacement, GMC Savana 2500 rear suspension service, and other rear applications listed for lowered trucks, dual rear wheel vans, and select SUVs.

This part cross-references Monroe Shocks & Struts 911085 for the same application.

Common Problems It Can Address

• Excessive rear-end bounce on loaded vans and trucks
• Reduced stability during towing or hauling
• Weak damping on lowered suspension setups
• Loss of control over rough pavement or uneven roads
• Premature shock fade during repeated heavy-duty use
