Key Features

• Remote reservoir design for increased cooling capacity
• Monotube internal design for consistent fade-resistant damping
• Velocity-sensitive digressive valving tuned for the application
• Smooth-body shock construction with zinc-plated finish
• 360-degree swivel banjo hose fitting for low-profile routing
• Rear position shock absorber for lifted Nissan Xterra use
• Eye 15.9 mm upper mount and Eye 14 mm lower mount

Product Line Details

The Bilstein B8 5160 series is aimed at lifted truck and SUV suspension setups that need more thermal capacity and suspension control than a standard shock. This line uses a remote reservoir layout to help manage heat during repeated compression cycles, while the monotube architecture supports stable damping response across changing terrain. For Nissan Xterra owners, the B8 5160 line provides a direct-fit rear shock solution matched to the vehicle’s lift range.

Detailed Description

Bilstein 25-277227 is a rear suspension shock absorber engineered for 2005-2015 Nissan Xterra models with 0-1 inch of rear lift. The remote reservoir increases oil volume and cooling capacity, while the monotube design helps maintain consistent damping under demanding conditions. Bilstein’s digressive valve settings are application-specific, giving the shock a controlled response for off-road use, towing, and uneven-road driving. The 46 mm body diameter, 12.95-inch collapsed length, and 20.89-inch extended length support proper rear suspension travel in the intended fitment range.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Shock Absorber Helps Address

• Excessive rear suspension bounce on lifted Nissan Xterra vehicles
• Heat buildup during repeated off-road compression cycles
• Reduced wheel travel from a standard rear shock setup
• Inconsistent damping response on rough terrain
• Rear suspension control loss after lift modifications

Installation Notes and Fitment

Fits 2005-2015 Nissan Xterra, rear, with 0-1 inch rear lift. Confirm rear suspension lift height and mount style before installation. The shock uses an eye-to-eye mounting configuration with a 15.9 mm upper eye and 14 mm lower eye, and the remote reservoir hose fitting is designed for a clean, low-profile layout. Part number 25-277227 is also referenced as 25277227 and 283877.
