Rear Shock Absorber for 2001-2006 BMW 330Ci & More - KYB 553239

Get controlled rear damping with the KYB shock absorber 553239, a Gas-a-just high-pressure monotube unit for the rear position on the listed applications. It fits many vehicles, among them the 2001-2005 BMW 325i, 2001-2006 BMW 325Ci and 2001-2006 BMW 330Ci. Its components and valving are designed specifically for the listed BMW applications, giving you controlled damping to replace a worn or leaking factory rear shock.

The Gas-a-just is a KYB gas shock absorber that uses a monotube layout with two separate working chambers: an air-free hydraulic piston-and-valve area for responsiveness, plus a high-pressure nitrogen gas section with a floating piston. Separating the gas and oil is designed for fade-free operation and instant response.

• High-pressure monotube design: keeps gas and oil apart to resist aeration fade.
• Triple chrome plated piston rod: ultra-smooth surface intended to reduce seal wear, since fluid leaking can cause shock failure.
• Added damping: adds up to 25% more damping performance over original equipment shocks.
• Recommended companions: KYB strut mounts SM5530 and KYB Strut Boot SB107 to help reduce noise and protect the unit.

See the "Vehicles it fits" section for the full list of applications and engine specifics. Sold individually; replacing both rear shocks as a matched pair is recommended for balanced ride control.
