Product Description

The KYB 5550017 is a Gas-A-Just high-pressure nitrogen gas monotube rear shock engineered for the 2018 and newer Jeep Wrangler (JL). This is the rear companion to KYB's 5550016 front shock, using the same monotube technology with two separate working chambers - an air-free hydraulic piston and valve area for control, and a high-pressure nitrogen gas area with a floating piston - to deliver instant on-demand performance alongside everyday ride comfort.

The velocity-sensitive valving system automatically adjusts to changing road conditions, while a micro-smooth, hard-chromed piston and seamless cylinder and eye-ring construction help extend service life and eliminate common seam failure points. This construction is engineered to eliminate the aeration and foaming that can affect twin-tube shocks under demanding conditions, delivering a firmer, more controlled ride.

This shock is a good fit for JL Wrangler owners running factory, stock-height suspension who want to upgrade rear shock performance beyond a standard twin-tube replacement. Since one source lists this part as out of production, confirm current availability and fitment with your supplier, and order the matching front shock (KYB 5550016) for a complete axle upgrade.
