Take command of loaded, towing, and off-road driving with the KYB shock absorber MonoMax (P/N 5650006), a high-pressure monotube gas shock built just for trucks. It installs as a direct-fit rear replacement for the 2009-2025 Ford F-150, delivering the added stability that heavier, more powerful, high-center-of-gravity vehicles demand.
The large-bore MonoMax is KYB's heavy-duty monotube suspension shock absorber, made for vehicles that do real work, go off-road, tow a trailer, or haul heavy loads. Its tough design automatically adjusts to driving conditions for fade-free performance.
- Monotube gas design: this KYB gas shock absorber provides up to 40% more damping performance than standard shock absorbers.
- Zinc-coated steel piston ring: a work-ready ring that provides a positive seal in the most extreme conditions.
- Off-road dust boot: a rubber boot protects the shaft and keeps dirt and debris away from the seals.
- Electronic-safety ready: engineered to help vehicles equipped with electronic safety systems (ESC, ABS, etc.).
Worn shocks can show up as excessive bouncing, nose-dive under braking, or poor control over bumps and dips. If a failed original rear shock is the cause, this MonoMax replaces it. Sold individually; replace both rear shocks together for balanced handling.
