KYB 5640006 Suspension Strut - Front

KYB MonoMax Front Leveling Strut for Silverado and Sierra

The KYB MonoMax 5640006 is a front suspension strut for truck applications that need added control and a level stance. Its extended-length body raises the front end without a separate spacer, making it a direct solution for leveling and load-handling needs on select Chevrolet Silverado 1500 and GMC Sierra 1500 models.

Key Features

• Extended-length body helps raise the front end for a level appearance
• Large-bore monotube design supports stability on heavier trucks and higher center-of-gravity vehicles
• Fade-free performance adjusts to changing driving conditions
• Work-ready zinc-coated steel piston ring for durability in demanding use
• Front suspension strut application for select 2014-2019 Chevrolet and GMC trucks
• KYB MonoMax 5640006 is built for towing, hauling, and off-road use

Product Details

The KYB MonoMax line focuses on truck suspension control, and the 5640006 follows that approach with a heavy-duty monotube construction and a higher spring seat. This front leveling strut is made for drivers who need more consistent handling under load, especially on trucks used for work, trail use, or trailer towing. It is a fitment-based solution for 2014-2018 Chevrolet Silverado 1500, 2014-2018 GMC Sierra 1500, 2019 Chevrolet Silverado 1500 LD, and 2019 GMC Sierra 1500 Limited, all in the front position and excluding electronic suspension applications. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Front-end rake on leveled truck builds
• Reduced control when carrying heavy loads
• Excess body motion during towing or hauling
• Inconsistent damping on rough roads or off-road surfaces
• Wear-related replacement needs on the front suspension strut
