Product Details

KYB MonoMax is the brand’s truck-focused shock line, built for demanding suspension loads and frequent changes in road conditions. Part number 565005 uses a large-bore monotube construction to improve handling stability and fade resistance, which is important on vehicles that tow trailers, haul cargo, or operate off-road. This part cross-references Gabriel 77717 for the same application. Compatible With 1997-2002 Ford Expedition rear and 1998-2002 Lincoln Navigator rear, this shock is a direct-fit option for rear air-leveling setups listed in the fitment data.

Common Problems This Shock Can Address

• Excessive rear bounce after bumps or dips
• Reduced stability when towing or carrying heavy loads
• Loss of control on rough pavement or unpaved roads
• Shock fade during repeated suspension movement
• Wear-related rear suspension looseness on Expedition and Navigator models

Installation Notes and Tips

Verify rear fitment by year, make, model, and air-leveling configuration before installation. The listed mount types are E2(12X38) at both the upper and lower positions, and the compressed, extended, and stroke dimensions should be checked against the original shock before replacement. Inspect surrounding suspension components, air-leveling hardware, and mounting points for wear or damage during service.
