This spoiler assembly—part number 5614100-SF01—isn’t just some “decorative piece” on the Dongfeng Dignity IX5. It’s a super important part that mixes sporty looks with useful aerodynamic perks, and it sits
right on the top edge of the rear trunk lid. It’s made specifically for 2019 to 2023 Dignity IX5s—all trims, from basic comfort to top-tier flagship—and it fits the car’s sleek, sporty rear design like a glove.
Unlike those cheap aftermarket spoilers that only make the car look “flashy,” this original one does two big useful things: first, it makes the IX5 look way sharper (the rear end feels tougher and more put-together), and second, it tweaks the airflow over the car—especially when you’re going fast—to keep it stable. Without it, the IX5’s rear might feel “light” when you’re driving at high speeds (like when you’re passing someone on the highway), and the whole car would lose that sporty vibe. Below’s a simpler breakdown of what this spoiler is all about:
This spoiler isn’t just for show—it actually works hard, both for how the car looks and how it drives:
When the IX5 goes over 80km/h, air rushes over the roof and hits the spoiler. The spoiler’s curved, angled shape doesn’t just let that air pass—it shoves that air downward instead. This creates what’s called “downforce” on the rear tires—basically, it pushes the back of the car onto the road. That stops the rear end from lifting up (a common problem with tall SUVs when they’re going fast), so the car feels solid on the road. No wiggling, no weird “floaty” feeling when you switch lanes quickly.
It’s shaped to match the IX5’s rear lines perfectly: sits perfectly flat against the trunk lid, and it’s the exact same width as the
rear bumper. The original version comes painted the same color as the rest of the car—no weird mismatched paint like you get with aftermarket spoilers. It looks like it came straight from the factory. For the sportier trims, some versions even have a subtle black edge that contrasts with the body color—makes the rear end pop a little more.
Most versions of this spoiler have a hidden high-mount brake light (it’s built into the bottom edge). When you hit the brakes, this light is way easier for cars behind to see—especially big trucks or other SUVs that might not spot the regular brake lights on the bumper as quickly. That lowers the odds of getting rear-ended, which is a huge plus.

It’s a “bolt-on” design, so it’s not too hard—but you gotta be precise to avoid gaps or water leaks. Here’s how to do it:
Wipe Down the Trunk Lid First: Use alcohol to clean the top edge of the trunk lid. This gets rid of dirt, so the spoiler sticks tight and no grime causes scratches later.
Line Up the Spoiler: Follow the factory’s pre-drilled holes as a guide. Set the spoiler on the trunk lid and mark where it goes—some versions even come with sticky tape to hold it in place temporarily, so it doesn’t slip while you work.
Secure It with Bolts: Take the metal bolts that come with the spoiler, push them through the spoiler’s brackets, and screw ’em into the trunk lid. Tighten ’em to 5–8N·m—don’t crank ’em too tight, though! You’ll crack the plastic if you overdo it.
Hook Up the Brake Light: Plug the spoiler’s wire into the trunk’s existing brake light connector. It’s a “one-click” fit—no wiring skills needed, just pop it in.
Seal It to Keep Water Out (Optional, But Smart): Put a little silicone sealant around the bolt holes. It’s not required, but it’ll stop rainwater from seeping into the trunk later.
Even with the pre-drilled holes, if you’re not sure you can line it up right, just have a Dongfeng 4S shop do the install. They’ll make sure it’s perfectly aligned and no water gets in—worth it to avoid mistakes!
Wash the spoiler with the rest of your car—use a soft sponge (skip hard brushes, they’ll scratch the paint!) and mild car wash soap. Stay away from harsh stuff like tire shine or bug removers on the spoiler’s paint—those can make the color fade fast.
For small scratches (like from a stray tree branch), grab a touch-up paint pen that matches your IX5’s color—you can get these at Dongfeng 4S shops. If the scratch is deeper, sand the spot gently with fine-grit sandpaper first, then slap on the touch-up paint. Good as new!
Every few months, check if the high-mount brake light works. Just ask someone to hit the brakes while you stand behind the car and look. If it’s out, the bulb’s probably burnt out—just pop off the clear plastic cover with a small screwdriver and swap in a new LED bulb. Super easy.
After a heavy rain, open the trunk and look for water stains. If you see any, the bolts might be loose (just tighten ’em a bit) or you need to reapply the silicone sealant around the holes. That’ll stop the leaks for good.
