Product Details

KYB MonoMax is the truck-focused product line from KYB, developed for demanding suspension use where stability matters. Part number 565086 uses a heavy-duty monotube construction that responds consistently as driving conditions change, helping maintain control on pavement, rough roads, and off-road terrain. The compressed length is 14.01 inches, extended length is 21.49 inches, and stroke length is 7.48 inches. Mounting is E2 style at both ends, with upper mount type E2(12.8X62) and lower mount type E2(12.8X41.3).

This shock absorber is listed for front lift replacement applications on 1988-1999 Chevrolet K1500, K2500, and K3500; 1992-1999 Chevrolet K1500 Suburban, K2500 Suburban, and Tahoe; 1992-1994 Chevrolet Blazer; 1988-1999 GMC K1500, K2500, and K3500; 1992-1999 GMC K1500 Suburban, K2500 Suburban, and Yukon. This part cross-references Rancho RSX17316 and Edelbrock 6360 for the same application. KYB 565086 is a direct-fit front shock option for lifted Chevrolet K1500 and GMC K2500 truck setups that need added damping control.

What It Helps Address

• Excessive front-end bounce on lifted trucks
• Reduced stability while towing or hauling heavy loads
• Loose or unsettled ride feel on rough roads
• Front suspension fade during repeated hard use
• Loss of control response in off-road driving conditions

Installation Notes

Verify lift height and mounting style before installation. This shock is listed for front replacement use on 4-6 inch lifted GM applications, so confirm compressed and extended length against the vehicle’s suspension travel. Inspect bushings, brackets, and mounting points for wear before installing the new shock absorber.

Quality Assurance

KYB builds the MonoMax line for heavy-duty truck service with a zinc-coated piston ring and protective dust boot to support durability in harsh environments. The design is intended to maintain consistent damping performance under demanding use.
