BMW 6 Series owners, these lift supports from Lift Supports Depot are exactly what you need when your trunk stops staying open! The 2-pack is perfect since you'll want to replace both sides for balanced performance. The 11.34 inch extended length matches the OEM specifications perfectly for 2005-2010 630i, 630Ci, 645, 650, and M6 Convertible models. Installation was surprisingly straightforward - the included instructions were clear, and I had both sides replaced in about 20 minutes with basic tools. The quality feels substantial and well-made, not cheap or flimsy like some aftermarket parts. They're compatible with multiple OEM numbers including PM3069, 0586wp, and 51247057340, so you can cross-reference with your original parts confidently. The difference is immediate - my trunk now opens smoothly and stays securely in place without sagging or slowly closing. The gas pressure feels just right - strong enough to hold the weight but not so strong that it's difficult to close. I've been using these for several months now through various weather conditions, and they've performed flawlessly without losing pressure. The value is excellent compared to dealership prices, and having a matched pair ensures consistent performance. If you're tired of having your trunk randomly falling on your head or struggling to keep it open while loading groceries, these lift supports provide a reliable, cost-effective solution that restores your BMW's functionality properly. Definitely recommended for any 6 Series owner dealing with weak trunk supports!
