Rear Shock Absorber for 2007-2017 Jeep Wrangler & More - KYB 5550019

Firm up rear-axle body control on your Jeep with the KYB Gas-a-just Shock Absorber 5550019, a rear shock absorber built on a high-pressure monotube gas design. It's a direct-fit replacement for the 2007-2017 Jeep Wrangler and the 2018 Jeep Wrangler JK — see the "Vehicles it fits" section for engine-level fitment.

• High-pressure monotube design: separates the nitrogen gas and the oil for fade-free operation and instant response.
• Triple chrome-plated piston rod: an ultra-smooth rod that helps reduce seal wear, since fluid leaking can be a cause of shock failure.
• Two working chambers: an air-free hydraulic piston and valve area for responsiveness and control, plus a high-pressure nitrogen chamber with a floating piston.
• Gas-a-just damping: KYB rates it to add up to 25% more damping over original-equipment shocks, with extra damping for vehicles that work, tow, and run larger, heavier tires and wheels.

The higher gas pressure responds quickly to improve steering response, and KYB notes the Gas-a-just helps keep electronic safety systems performing as designed, since those systems depend on the suspension, brakes and tires. This is a rear suspension shock absorber; it is sold individually, and replacing both rear shocks as a matched pair is recommended for balanced ride control.
