This Fleetguard maintenance kit has everything you need for a complete service on your Cummins engine! The kit includes the LF9009 lube filter, FS1000 fuel/water separator, and WF2077 water filter - all genuine Fleetguard quality. I used this on my Dodge Ram with the 6.7L Cummins, and the installation was straightforward with basic tools. The filters fit perfectly with no issues, and the quality is exactly what you'd expect from Fleetguard - heavy-duty construction that'll handle tough conditions. What's great is having all the filters together in one kit - no running to multiple stores or ordering separately. The lube filter does its job keeping the oil clean, the fuel/water separator catches water and contaminants beautifully, and the water filter completes the protection package. If you do your own maintenance to save on shop costs, this kit makes it so much easier. The filters are designed specifically for Cummins engines, so you know they'll perform exactly as intended. I've noticed smoother running and better fuel economy after installing fresh filters too. For the price compared to buying individually, it's a solid deal that keeps your engine running strong. If you're due for service and want OEM-quality without the dealership markup, this kit has you covered completely. Just make sure you have a filter wrench and some basic mechanical knowledge!
