KYB Suspension Shock Absorber P/N:553177
Firm up ride control and keep your Jeep composed with the KYB Gas-a-just High Pressure Monotube Gas Shock 554365, a rear suspension shock absorber that drops in as a direct-fit replacement for the 2007-2017 Jeep Wrangler and 2018 Jeep Wrangler JK. See the Buyer's Guide tab for engine-level fitment. This monotube design separates the gas and oil so the shock resists fade and responds instantly, with components and valving designed specifically for Jeeps.
The higher gas pressure helps improve steering response and, since electronic safety systems depend on the suspension operating as intended, helps keep those systems performing as designed.

What is the KYB Gas-a-just 554365?
It's a rear high-pressure monotube gas shock absorber with components and valving designed specifically for Jeeps, separating gas and oil for fade-free operation and instant response.
Which vehicles does it fit?
It's a direct-fit rear replacement for the 2007-2017 Jeep Wrangler and 2018 Jeep Wrangler JK. Check the Buyer's Guide tab to confirm fitment for your vehicle.
How is a monotube shock different from a twin-tube?
The monotube design keeps the high-pressure nitrogen gas and hydraulic oil in separate chambers, which helps resist aeration fade and provides instant, responsive damping.
Does this shock add extra damping?
Yes. KYB states the Gas-a-just adds up to 25% more damping performance over original equipment shocks, with extra damping for vehicles that work, tow, and run larger, heavier tires and wheels.
Should I replace shocks in pairs?
Shocks are sold individually; this listing is for one. Replacing both sides on the same axle together is recommended for balanced, even ride control.
