Is your BMW X5's tailgate getting heavy? Does it slam shut or fail to stay open? Your lift support struts (gas springs) are worn out. This is a complete PAIR of brand new replacements specifically for the 2000-2006 BMW E53 X5 model. They replace OEM part number 51248402405. Each strut is black, made of steel, and has the correct dimensions: extended length of 20.78 inches, compressed length of 14.53 inches, and a 6.25-inch stroke. They install on the left and right sides of the tailgate/trunk. Installation is usually simple – just a couple of clips or bolts. Once installed, your tailgate will lift smoothly and hold securely in the open position again. From BOXI with a 1-year warranty. A super common fix for these SUVs.
