KYB Gas-a-Just Rear Shock Absorber for 2020+ Ford F-250 Super Duty 4WD, Part 5540053

The KYB Gas-a-just monotube shock absorber has additional performance advantages over the traditional twin-tube design: It can instantly, automatically adjust to your performance needs and never experiences fade due to aeration. The KYB Gas-a-just has two separate working chambers: An air-free hydraulic piston and valve area for responsiveness and control, and a second high-pressure nitrogen gas area with a floating piston that provides a comfortable ride during normal driving and adds instant performance on demand.

• Electronic safety systems depend on the suspension, brakes and tires operating as the vehicle manufacturer intended. The KYB Gas-a-just helps keep Electronic Safety Systems performing as designed.

The KYB Gas-a-Just monotube rear shock absorber, part number 5540053, is engineered for 2020 and newer Ford F-250 Super Duty 4WD models without the Off-Road Suspension or Tremor Package. Its monotube design uses separate hydraulic and high-pressure nitrogen gas chambers to deliver responsive damping, improved control, and consistent performance during changing driving conditions.

Unlike traditional twin-tube shocks, the KYB Gas-a-Just automatically adjusts to driving demands and resists performance fade caused by aeration. The air-free hydraulic piston and valve area supports precise suspension control, while the floating piston and pressurized nitrogen chamber help provide a comfortable ride during normal driving and additional damping performance when hauling, towing, cornering, or traveling over uneven roads.
