What are Fender Flares?

They serve an additional purpose as they can prevent dirt and stones from spraying away from the tires and damaging your truck’s paint.

Whether you want full extensions or just narrower gaps for downhill or rock crawling, with the right set of fender flares for GMC Sierra you can give your truck a completely custom look.

There are many advantages to adding fender flares to a GMC Sierra:

Choosing the Right Fender Flares for Your GMC Sierra

When choosing fender flares for your GMC Sierra, there are a few important factors to consider. The year and model of your vehicle should be taken into account when selecting the right fender flare kit. Some kits may not fit certain models, so make sure you are aware of what type of flares will work best with your specific vehicle before purchasing.

Size is another factor to consider when selecting fender flares for your GMC Sierra. You want to make sure that the flares fit properly on each side of the vehicle, so it’s important to measure carefully and check that the flares are compatible with the size of your wheels. Fender flares also come in different configurations, so be sure to choose a size that meets your style requirements as well as any restrictions imposed by local regulations.

Material can also play an important role in finding the right fender flare package for your GMC Sierra. Flares made from durable ABS materials offer a more resistant plastic construction but may lack flatness or uniformity in comparison to other plastic materials used like polypropylene plastic or polyurethane foam covered with vinyl fabric-like material or molded rubberized coatings which are much stronger and more flexible than plastic products but tend to be more expensive. The effectiveness and durability of each material differs depending on the environment it is exposed to so research carefully before purchasing one finish over another.

Style and design

When it comes to customizing your GMC Sierra, one popular choice that can make a real difference and give your truck added curb appeal is the installation of fender flares. Not only do these enhance the look of your Sierra, but they also provide some added protection for all that hard work you’ve done in personalizing and upgrading it.

Fender flares come in a variety of different styles from a wide range of manufacturers, so finding the one that’s just right for you is easier than ever. You can choose from sleek designs with classic lines to bolder looks with an aggressive flair. There are even some specialty models that allow you to customize the appearance by changing the color or shape of the flare itself.

The materials available can vary as well, ranging from lightweight plastic to more durable aluminum or steel. Depending on where you live and what type of terrain you drive on, having fender flares made with more substantial material can be beneficial in providing extra stability and protection against things like dirt, rocks and other debris. Additionally, each type will require a slightly different installation technique so be sure to check manufacturer guidelines before beginning.

Compatibility with your truck

Fender flares for the GMC Sierra come in several varieties, and it’s important to determine which set is compatible with your truck. For 2019 models or newer, GMC offers OEM fender flares designed specifically for the vehicle. These offer a precise fit and look great with a range of paint colors.

Aftermarket options such as steel or vinyl fender flares can also provide coverage for your wheels, but you should take extra care to check compatibility with your particular model. Additionally, these aftermarket products may require professional installation to ensure precise fitting and high-quality protection.

When selecting fender flares for your Sierra, be sure to consider the material and function that’s best suited to your lifestyle preferences, budget and needs.

Maintenance and Care for Fender Flares

Caring for your fender flares is an important part of proper maintenance and can help to maximize the lifespan of your GMC Sierra’s flares. The following steps should be taken to ensure that your fender flares stay in the best condition:

– Wash the fender flares regularly by hand or with a gentle car cleaner.

– Inspect the rubber gasket for any discoloration and replace if necessary.

– Keep the hardware clean and free from corrosion by applying a light coat of Scotch-Brite or other lubricant every few months.

– Touch up scratches with touch up paint specifically meant for use on fender flares.

– To prevent fading, apply a coat of wax to the fender flares every 4 months.

– Check mounting and adhesion regularly, tightening fasteners as needed, and reseal all connections with caulk at least once per year.

Cleaning and washing

Before you begin adding any fender flares to your vehicle, it is important to prepare the surface of your GMC Sierra. In order to get a good and secure adhesive bond with the fender flares, you must make sure that the surface is clean.

Start by washing your GMC Sierra with a mild car cleaner and water. Then use a degreaser to remove any oil or dirt from the body surface. After you are finished washing and degreasing, take an all-purpose cleaner and wipe down the area. This will help ensure there is no dust or debris on the surface when applying the fender flares.

Protecting and restoring

Fender flares are a great way to protect your GMC Sierra’s wheel wells and fenders. Not only do they guard against the elements, they also can be used to restore your truck’s original look or enhance it with a customized look. If you choose to go that route, there are a few things you need to know before you take the plunge.

First, consider what kind of materials would be best for your style and budget. Traditional fender flares come made from either ABS plastic or flexible rubber; both options provide excellent protection and will last a long time but may require additional care when cleaning or storing them for long periods of time. If you’d like something that looks more like metal, opt for flares made from chrome-plated steel or aluminum – these will stand up against severe weather conditions better than plastic and have an attractive luster that stands out from other vehicles on the road.

Second, pay attention to how the flares fit into the wheel wells of your vehicle so that you get as seamless of an appearance as possible. Neither ABS nor rubber are super-flexible; rather than try stretching them into place with your hands, use a crowbar (or similar tool) for ease of installation – make sure the protruding bolt heads align with the holes in each flare. Movement along any one edge should be minimal so keep an eye out for gaps between panels or at seams along edge-fittings and adjust accordingly if necessary before securing all nuts firmly in place with appropriate tools). You may also want to employ a silicone sealant (available at most auto parts stores) to ensure no moisture can seep behind each panel which could damage your truck’s body over time due to rust formation especially in salt-rich climates.

Troubleshooting common issues

Sometimes, minor issues can occur when installing fender flares on your GMC Sierra. However, many of these issues can be easily resolved in a few short steps. Here are some common issues and ways to resolve them:

-Improper Fitment: If the fender flares appear to be too tight or loose in certain areas, the installation may need to be tweaked slightly. Use a set of adjustable pliers to gently bend the flare into place.

-Weird Corner Parts: Depending on the model of your GMC Sierra, there might be certain corners you cannot seem to fit properly when installing your new fender flares. If this is the case, you will have to cut them off with a pair of aviation tin snips. The spots where you have removed material do not need to be filled as they won’t affect the performance of your fender flares.

-Dirty Flares: Your new fender flares may come with an excess dirt that needs to be cleaned away before installation can begin. To remove this dirt, simply scrub your new fender flares using warm soapy water and a soft-bristled brush. Be sure not to use any abrasive materials such as steel wool.
