When you need KYB struts built to handle real truck work, the KYB MonoMax Suspension Strut (MPN 5640003) delivers heavy-duty, high-pressure monotube gas damping as a direct-fit front replacement for the 2014-2020 Ford F-150. Engineered for the 4WD F-150, the large-bore MonoMax adds the stability that heavier, more powerful and high-center-of-gravity vehicles demand — automatically adjusting to driving conditions for fade-free performance whether you tow, haul or head off-road.

  • Large-bore monotube design: heavy-duty construction built for handling, control and durability.
  • Zinc-coated steel piston ring: provides a positive seal in the most extreme conditions.
  • Up to 40% more damping: delivers up to 40% more damping performance than standard struts.
  • Off-road ready: engineered to help vehicles with electronic safety systems (ESC, ABS) and includes an off-road dust boot.

Struts wear gradually; signs the front struts may need replacing include excessive bounce, nose-dive under braking, poor handling, uneven tire wear or fluid seeping from the strut body. Sold individually — order two to replace both front struts as a matched pair for balanced handling. See the Buyer's Guide tab to confirm your exact engine and configuration.

Frequently Asked Questions

Does this KYB MonoMax strut fit my Ford F-150?

Yes — MPN 5640003 is a direct-fit front strut for the 2014-2020 Ford F-150, and KYB specs it for the 4WD F-150. Check the Buyer's Guide tab to confirm your exact engine and configuration.

Is this a front or rear strut?

It is a front suspension strut, per the catalog position for the listed application.

How many struts do I need?

Struts are sold individually, so this listing is for one unit. Order two to replace both front struts as a matched pair for even, balanced handling.

What is a high-pressure monotube gas strut?

A monotube gas design uses a single tube and a pressurized gas charge to control damping, giving the large-bore MonoMax up to 40% more damping performance than standard struts.

What are signs my struts may need replacing?

Excessive bouncing, nose-dive under braking, a rougher ride, uneven tire wear or fluid seeping from the strut body are common signs. Diagnose the cause before replacing.
