KYB Suspension Shock Absorber P/N:3440112
Firm up a working truck's ride with the KYB Gas-a-just Shock Absorber 554375, a high-pressure monotube gas shock that installs in the FRONT position on the 2009-2010 Dodge Ram 1500, the 2011-2018 RAM 1500, and the 2019-2024 RAM 1500 Classic. This KYB shock absorber runs a monotube design instead of the traditional twin-tube, with two separate chambers — an air-free hydraulic piston and valve area for control, plus a high-pressure nitrogen gas area with a floating piston that supports a comfortable ride during normal driving. See the "Vehicles it fits" section for the full engine-level fitment.

This part cross-references / interchanges with the following part numbers:
Does this KYB gas shock absorber fit my 2011-2018 RAM 1500?
Yes, it is listed for the FRONT position on the 2011-2018 RAM 1500. Check the "Vehicles it fits" section for the full list of vehicles and engines it fits.
What is the difference between a monotube and a twin-tube shock?
This Gas-a-just monotube keeps the gas and oil in separate chambers, which helps it avoid fade from aeration and respond quickly, unlike a traditional twin-tube design.
How much more damping does this shock provide?
KYB states the Gas-a-just adds up to 25% more damping performance over original-equipment shocks, with valving designed specifically for Dodge Rams.
Should I replace both front shocks at the same time?
This listing is for one shock. Replacing both sides together as a matched pair is recommended for balanced, even damping across the axle.
Is this shock a good value at this KYB shock absorber price?
It uses a high-pressure monotube design with a triple-chrome-plated piston rod meant to reduce seal wear, and adds damping over OE for trucks that work, tow, and run heavier wheels and tires.
