Thinking about putting 5th gen mirrors on 4th gen ram trucks is one of those projects that once you see it done, you can't un-see how good it looks. If you're driving a 4th gen—basically anything from 2009 to 2018 (or the Classic models)—you know the "moose ear" struggle. The factory tow mirrors are iconic, sure, but they're also a bit dated. The 5th gen mirrors, which started appearing on the 2019+ models, bring a much sharper, more modern vibe that honestly makes the older trucks look five years newer just by sitting in the driveway.
But as with most things involving modern trucks, it's not exactly a "plug-and-play" situation where you just swap parts and go get a coffee. There's a bit of a learning curve, some specific wiring to consider, and a few parts you'll need to gather before you start ripping your door panels off.
Why Even Make the Switch?
Let's be real for a second: the 4th gen tow mirrors aren't bad. They do their job. But if you've ever sat behind the wheel of a newer 5th gen, you notice the glass quality and the layout right away. The 5th gen mirrors offer a much better field of vision. Instead of the flip-up style that everyone jokes about, these new ones are fixed in a horizontal position but have a much more intuitive blind-spot mirror built-in.
Then there's the lighting. The LED turn signals and puddle lights on the 5th gen versions are significantly brighter and more "high-end" looking than the old school bulbs or basic LEDs on the 4th gens. Plus, if you're into the aesthetic, the 5th gen mirrors just look beefier. They fill out the lines of the truck better, especially if you've got a lift or some wider tires.
The Compatibility Problem
Here is where the headache usually starts for most guys. You can't just go to a dealership, buy a set of mirrors meant for a 2022 Ram 1500, and expect them to bolt onto your 2014. The mounting footprint is different. The bolt patterns don't line up, and the wiring harness is a completely different animal.
If you try to "force" it, you're going to end up with a set of mirrors that shake, vibrate, or worse, don't work at all. Thankfully, the aftermarket world saw this coming a mile away. Companies have developed conversion kits specifically for putting 5th gen mirrors on 4th gen ram pickups. These kits usually include an adapter plate or a modified mirror base that matches the 4th gen door contour perfectly while holding the 5th gen mirror arm.
What You'll Actually Need
Before you dive into this, you need to know what's on your truck right now. Do you have power-folding mirrors? Do you have memory seats? Are they heated?
- The Mirrors Themselves: You'll want the "conversion" style mirrors. These are 5th gen style mirrors manufactured with a 4th gen mounting base.
- Wiring Harnesses: If your truck didn't come with certain features (like puddle lights or turn signals) and you want them now, you'll need a specific harness to tap into the truck's computer or door modules.
- Support Brackets: Tow mirrors are heavy. If you're upgrading from small sport mirrors to the big 5th gen style tow mirrors, don't skip the interior reinforcement brackets. Without them, your mirrors will shake every time you hit a bump, and that'll drive you crazy within ten minutes of driving.
The Installation Process
Installing 5th gen mirrors on 4th gen ram doors isn't a job that requires a master mechanic, but you'll want to set aside a Saturday morning and have some basic tools ready. You're going to be taking the door panels off, which is always a bit of a nerve-wracking experience if you're worried about snapping those little plastic clips.
Removing the Old Mirrors
First things first, you've got to get the door panels loose. There are usually a few hidden screws—one behind the door handle pull and maybe one or two along the bottom or side. Once those are out, it's just a matter of carefully prying the panel up and out.
Don't just yank it. You've got wires for the windows and locks still attached. Once you have enough space, reach in and unplug the mirror harness. From there, it's just three nuts holding the mirror to the door. Hold onto the mirror from the outside while you undo the last nut, or you're going to have a very expensive "clunk" on your driveway.
Bolting on the New Style
If you bought a proper conversion kit, the new mirror should slide right into the factory holes. This is the moment of truth. If the studs line up, you're golden. Tighten them down, but don't go crazy—you don't want to warp the door skin.
Now, the wiring is where you might spend most of your time. If you're lucky, the connectors match up. If you're upgrading features, you might have to run a couple of wires through the door boot and into the footwell. It's tedious, but totally worth it when you see those LED puddle lights kick on for the first time.
Dealing with Features and Functionality
One thing people often ask is, "Will my power-fold still work?" The answer is: it depends. If your truck had power-folding mirrors from the factory, and you bought power-folding conversion mirrors, it's usually a straight swap.
However, if your truck didn't have power-fold and you're trying to add it, you're looking at a bit more work. You might need to swap out your door modules and even the master switch on the driver's side. Some guys use an AlphaOBD tool to tell the truck's computer that it now has power-folding mirrors. It's a bit of a rabbit hole, but for many, having that 5th gen functionality on an older truck is the ultimate goal.
The Mirror Glass and Heat
Most of the conversion mirrors come with the heating element. In most cases, if your 4th gen had heated mirrors, the new ones will work right out of the box. The 5th gen glass is actually pretty great in the winter—it seems to clear up a lot faster than the older style glass. Just make sure the pins in the connector match up before you button everything back together.
Is It Worth the Hassle?
Honestly? Yeah, it really is. When you see 5th gen mirrors on 4th gen ram trucks, it just changes the whole profile of the vehicle. The 4th gen is a classic design—it's arguably one of the best-looking trucks Ram ever made—but the mirrors were always the one part that felt a little "plastic-heavy."
The 5th gen mirrors bring in more modern geometry. They look more integrated and less like an afterthought. From a practical standpoint, the visibility is a massive upgrade. The way the blind-spot glass is positioned on the 5th gen mirrors makes merging in traffic way less stressful, especially if you're pulling a trailer.
Common Mistakes to Avoid
Before you go out and buy the first set you see on eBay, keep a few things in mind. First, avoid the super cheap "no-name" mirrors if you can. A lot of the time, the glass in those is thin and vibrates like crazy at highway speeds. There's nothing worse than looking in your mirror and seeing a blurry mess because the housing isn't sturdy enough.
Second, make sure you double-check your temperature sensor. On many 4th gen Rams (especially the 2013+ models), the ambient air temperature sensor is located in the driver's side mirror. If you buy a mirror that doesn't have a spot for that sensor, your truck's AC won't work right, and you'll get a check engine light because the computer doesn't know how cold it is outside. Most good conversion kits account for this, but it's always worth verifying.
Final Thoughts
Swapping to 5th gen mirrors on 4th gen ram is a solid weekend project that pays off every time you look at your truck. It bridges the gap between the classic 4th gen body style and the modern tech of the newer generation. It's one of those rare mods that is both a cosmetic win and a functional improvement.
Take your time with the wiring, make sure you have the right brackets to prevent vibration, and you'll be wondering why you didn't do the swap years ago. It's a subtle change that makes a huge statement, giving your trusty 4th gen a fresh lease on life.
