Description

Tame heavy loads and rough roads with the KYB shock absorber MonoMax 565121, a high-pressure monotube gas shock that installs in the front position of the 2005-2024 Ford F-250 Super Duty, 2005-2025 Ford F-350 Super Duty, 2005-2022 Ford F-550 Super Duty, and 2005-2016 Ford F-450 Super Duty. The large-bore KYB MonoMax is a heavy-duty monotube design built for trucks that do real work — towing a trailer, hauling heavy loads, or heading off-road — where its damping automatically adjusts to driving conditions for fade-free control.

Large-bore monotube design: a heavy-duty build made just for trucks, delivering strong handling, control, and durability.
Up to 40% more damping performance than standard shock absorbers as a maximum-performance suspension upgrade.
Zinc-coated piston ring: provides a positive seal in the most extreme conditions.
Rubber dust boot: protects the shaft and keeps dirt and debris away from the seals.
Engineered to help vehicles with electronic safety systems (ESC, ABS, etc.).

This KYB gas shock absorber is a direct-fit replacement for the listed Ford Super Duty applications; see the Buyer's Guide tab for the full engine-level fitment.
