KYB Suspension Shock Absorber P/N:349047
KYB 555051 rear shock absorber for the 2005-2021 Nissan Frontier damps rear suspension movement using a high-pressure nitrogen gas chamber. This KYB gas shock absorber adds up to 25% more damping performance than original equipment shocks.
Fluid on the shock body, a bouncy or floating ride, or a loose-feeling rear end can mean a shock is wearing out. Those signs alone do not prove the shock is at fault; a worn suspension bushing or an out-of-balance tire can feel much the same. This listing is one shock, and both rear sides are normally replaced together.
It fits the 2005-2021 Nissan Frontier, with components and valving designed specifically for that truck.

This part cross-references / interchanges with the following part numbers:
Does this KYB shock absorber fit the 2005-2021 Nissan Frontier?
Yes. KYB 555051 is a rear shock absorber for the 2005-2021 Nissan Frontier, and the truck takes two.
What does the floating piston in the KYB 555051 do?
The floating piston separates the high-pressure nitrogen gas area from the hydraulic oil area. The gas side gives a comfortable ride in normal driving and adds instant performance on demand.
Why does this KYB absorber 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 there to reduce seal wear.
What does fluid on the body of a KYB rear shock absorber mean?
Wet or oily residue on the shock body can mean the seal is wearing. Look with the vehicle parked and the engine off, and have a shop confirm.
Does 56200EB085 interchange with KYB 555051?
Yes. 56200EB085 is one of the numbers KYB 555051 replaces, along with 56200ZP025 and four others on the Interchange line.
