The Bilstein B6 2000 Nissan Xterra SE Rear 46mm Monotube Shock Absorber (part 24-184908) is a rear replacement damper listed for the 2000 Nissan Xterra SE. Its single-tube monotube body is the design feature to look for if you want damping that holds steady over repeated bumps, whether you are driving rough gravel or a trail. Replacing a worn rear unit with a dedicated Bilstein B6 gives the rear axle a firmer, more controlled feel than a tired factory shock.
Before ordering, confirm that this rear shock matches your exact model year, drivetrain, and lift height, because fitment information for this Bilstein B6 series is not consistent across sources. Rear clearance around the factory sway bar is the fitment point most likely to cause trouble, so check that against your suspension setup before you buy. Searches for Bilstein 24-184908, 2000 Xterra SE rear monotube shock, Xterra rear shock upgrade, 46mm monotube rear shock, and B6 Xterra rear shock replacement all point to the same application.
