Is your 2004 Ford or Lincoln truck feeling a bit shaky or making weird vibrations? Might be time for new engine mounts! This A-Premium kit gives you both front mounts – the left AND the right side – so you can tackle the job all at once. It's a perfect fit for the 2004 Ford Expedition with the 5.4L V8, the 2004 Ford F-150 with either the 4.6L or 5.4L V8, and the 2004 Lincoln Navigator with the 5.4L V8. Quick note: this kit includes the mounts themselves, but NOT the mounting brackets. So make sure that's what you need. The part numbers you might be cross-referencing include 4L1Z6038DA, 4L3Z6038DG, A5413, A5414, EM-3150, EM-3151, and a few others listed. We build these mounts tough, using superior materials and putting them through harsh testing to make sure they meet or even beat the original equipment (OE) specs. They're built to handle the engine's weight and movement for a smooth, quiet ride. Each kit comes with one front left motor mount and one front right motor mount. And we back them up with a solid one-year, unlimited-mileage guarantee for your peace of mind. We've got a ton of other car parts too, so you can fix up your ride with confidence. Get those mounts swapped and enjoy a smoother drive!
