What vehicle does this KYB shock fit?
It is designed as a rear monotube OEM replacement shock for the 2018-2023 Jeep Wrangler. See the "Vehicles it fits" section to confirm engine-level fitment for your vehicle.
How is a monotube gas shock different from a twin-tube?
The high-pressure monotube separates the gas and oil into two chambers for fade-free operation and instant response, so it won't experience fade due to aeration like a traditional twin-tube.
Is this suspension shock absorber good for towing and larger tires?
Yes. KYB Gas-a-just monotubes are designed for vehicles that work, tow, and run larger, heavier tires and wheels.
Why does it have a triple chrome-plated piston rod?
Fluid leaking can be a cause of shock failure, so the ultra-smooth triple-chrome-plated rod is made to reduce seal wear.
Should I replace shocks in pairs?
This listing is for one shock. Replacing both sides on the same axle together is recommended for balanced, even ride control.
