Jeep Commander Rear Spoilers: All You Need to Know

The rear spoiler on your SUV, you can find either on its roof or its trunk. Its job is twofold: add a touch of unmistakable Jeep style and reduce the effects of air resistance on the vehicle's body. In short: turn a few heads on the road while improving aerodynamics and handling and making the drive more comfortable and controlled.

How a rear spoiler works is simple. It forces air to move across vehicle body parts in a way that cuts drag, and this improves traction somewhat. It can sometimes even give a vehicle a slight fuel economy bump.

How well one works to that end, though -- that depends on materials. Most rear spoilers are made of basic acrylonitrile butadiene styrene (better known by the shorthand "ABS plastic"). There are more durable options you can buy online these days, though, comprised of everything from fiberglass and silicone to ultra-resilient carbon fiber.

All of them get built to last, but that doesn't mean wear and tear doesn't happen from time to time. In fact, everything from lousy weather to rough roads, even the smallest debris, can scuff or even crack them. That's not to mention what can happen if one gets into an accident. If any of this is the case for your rear spoiler, you've come to the right auto parts store.
