Product Details

KYB MonoMax 5640013 is part of KYB’s truck-focused MonoMax line, a product family built around control, durability, and load-handling performance. For Ford F-150 owners who need a front suspension strut for towing, hauling, or off-road driving, this unit uses a monotube layout and a large bore body to help maintain stable handling under demanding use. The listed dimensions include a compressed length of 17.2, extended length of 21.46, and stroke length of 4.26, with lower mount type E2(20x60) and upper mount type S1(12MM). This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. The KYB 5640013 is a direct-fit option for the specified Ford F-150 front suspension application.

What It Helps Address

• Excessive front-end bounce on a Ford F-150
• Reduced control when towing or hauling heavy loads
• Suspension fade during repeated rough-road driving
• Front suspension instability on higher center-of-gravity trucks
• Wear-related replacement needs for the original front strut

Installation Notes and Tips

Verify the vehicle is a 2009-2013 Ford F-150 with front suspension and without Heavy Duty or Sport Suspension before ordering. Confirm mount style and dimensional match against the existing strut, including lower mount E2(20x60) and upper mount S1(12MM). Because this is a suspension strut, professional installation and a post-installation alignment are recommended after replacement.

Quality Assurance

KYB builds the MonoMax line for truck-duty use with a focus on control, durability, and consistent damping performance. The zinc-coated steel piston ring and off-road dust boot support long-term service in demanding conditions. Part number 5640013 is engineered for the listed Ford F-150 front application.
