KYB Suspension Shock Absorber P/N:555609
KYB 5550009 rear shock absorber for the 2016-2020 Chevrolet Tahoe damps rear suspension movement with a high-pressure nitrogen gas chamber. This KYB shock absorber is a high pressure monotube gas shock.
A worn suspension shock absorber can show up as a bouncy ride, fluid on the shock body or uneven tire wear. These signs alone do not prove the shock is the problem, since worn tires can make a ride feel loose too. Rear shocks are normally replaced as a pair; this listing is one shock, and the rear axle takes one on each side.
It fits the 2016-2020 Chevrolet Tahoe, and its components and valving are designed for the Police package. The Gas-a-Just monotube adds damping over the OE design for vehicles that work, tow and run larger, heavier tires and wheels.

Will this work as a shock absorber for the 2016-2020 Chevy Tahoe?
