Extending these fender flares improves the truck’s stance while providing better protection from mud and debris. When you drive a Jeep Gladiator, you know the factory fenders leave a lot of your tires exposed. Adding Jeep Gladiator fender flare extensions is a smart upgrade for both looks and function.
These extensions bolt on to your existing fenders, widening the coverage area. They help you stay legal if you run wider tires or aftermarket wheels. Plus, they give your Gladiator a more aggressive, finished appearance.
Jeep Gladiator Fender Flare Extensions
Before you buy, understand what these parts actually do. They are not full replacement fenders. Instead, they attach to the factory flares to extend the outer edge. This keeps your tires from sticking out too far, which can cause issues with law enforcement and throw rocks at other vehicles.
Most kits use a simple bolt-on installation. You don’t need to cut or modify your truck’s body. This makes them a popular choice for DIY owners who want a weekend upgrade.
Why You Need Fender Flare Extensions
Your stock Gladiator fenders are designed for the factory tire size. Once you upgrade to 35-inch or 37-inch tires, the tread often extends past the flare. This is where extensions come in.
- Legal compliance: Many states require tires to be covered by fenders.
- Protection: Extensions block mud, water, and small rocks from hitting your paint.
- Appearance: They fill the wheel well gap and create a wider, tougher look.
Types Of Extensions Available
There are several styles to choose from. The right one depends on your tire size and personal taste.
Rugged Ridge XHD Extensions
These are a popular choice for Gladiator owners. They add about 1.5 inches of coverage per side. They are made from durable ABS plastic and come with a textured black finish. Installation requires drilling into the stock fender, but the kit includes templates.
Bushwacker Pocket Style Extensions
Bushwacker offers a pocket-style design that matches the factory look. These extensions cover the entire wheel opening. They provide more coverage than simple add-ons, but they are also more expensive.
Universal Fit Extensions
Some brands sell universal strips that you cut to length. These are cheaper but may not look as clean. They work best if you only need a small amount of extra coverage.
How To Install Jeep Gladiator Fender Flare Extensions
Installation is straightforward if you follow these steps. You will need basic hand tools and a drill. Plan for about two hours per side if you work slowly.
- Park on a level surface and turn the wheels for access.
- Clean the factory fender area with soap and water. Remove any dirt or wax.
- Dry the surface completely. Use rubbing alcohol for a final wipe.
- Position the extension against the stock flare. Use the included template to mark drill holes.
- Drill pilot holes using a 1/8-inch bit. Go slow to avoid cracking the plastic.
- Attach the extension with the supplied screws and clips. Tighten evenly.
- Repeat for all four corners. Check alignment before final tightening.
Some kits use adhesive instead of screws. These are easier to install but may not hold as well off-road. For heavy use, always choose a screw-on kit.
Tools You Will Need
- Power drill with 1/8-inch and 1/4-inch bits
- Phillips screwdriver
- Socket set or wrench
- Measuring tape
- Rubbing alcohol and clean rags
- Safety glasses
Common Installation Mistakes
Even simple jobs can go wrong. Avoid these errors.
- Drilling too close to the edge: This can crack the factory flare.
- Not cleaning the surface: Dirt prevents the extension from sitting flush.
- Skipping the template: Always test fit before drilling.
- Over-tightening screws: This can strip the plastic or warp the extension.
Benefits Of Using Fender Flare Extensions
Beyond the obvious coverage, extensions offer several advantages.
Improved Off-Road Performance
When you drive through mud or sand, the tires fling debris everywhere. Extensions keep more of it off your truck and out of your windows. They also reduce the spray that hits other vehicles on the trail.
Better Resale Value
A Gladiator with properly fitted extensions looks more complete. Potential buyers see a truck that was upgraded with care. This can help you get a higher price when you sell.
Customization Options
Extensions come in different finishes. You can get matte black, gloss black, or even paintable versions. Some owners match them to their body color for a seamless look. Others leave them black for contrast.
Choosing The Right Material
Not all extensions are made the same. The material affects durability and appearance.
ABS Plastic
This is the most common material. It is lightweight, flexible, and resists cracking. Most aftermarket extensions use ABS. It holds up well to trail abuse and UV exposure.
Polyurethane
Polyurethane is more flexible than ABS. It bends rather than breaks if you hit a rock. However, it can be harder to paint and may fade faster in sunlight.
Fiberglass
Fiberglass extensions are less common. They are stiff and can crack under impact. They are best for show trucks that see little off-road use.
Compatibility With Different Tire Sizes
Extensions are designed for specific tire widths. Check the product specs before buying.
- Stock tires (255/70R18): Extensions are optional but add style.
- 33-inch tires: Most extensions provide adequate coverage.
- 35-inch tires: You need at least 1.5 inches of extension per side.
- 37-inch tires: Look for wider extensions or full replacement fenders.
Measure your tire’s widest point from the stock fender edge. This tells you how much extension you need.
Cost Considerations
Prices vary widely based on brand and material. Expect to pay between $100 and $400 for a set of four extensions. Installation is free if you do it yourself.
Higher-priced kits often include better hardware and thicker plastic. Cheap kits may warp or fade quickly. Spend a little more for a known brand.
Maintenance Tips
Extensions require minimal care. Wash them with soap and water during regular truck cleaning. Avoid harsh chemicals that can dull the plastic.
Check the screws every few months. Off-road vibrations can loosen them. Tighten as needed to prevent rattling.
If you paint your extensions, use a flexible primer and automotive paint. This prevents peeling and chipping.
Frequently Asked Questions
Will fender flare extensions fit all Jeep Gladiator models?
Most extensions are designed for the Gladiator Sport, Overland, Rubicon, and Mojave. Always check the product description for model year compatibility. Some kits may not fit models with factory fender flares that are already wider.
Do I need to remove the stock fender flares to install extensions?
No. Extensions attach directly to the existing flares. You do not remove anything. This makes installation faster and less invasive.
Can I install extensions without drilling?
Some kits use 3M adhesive tape instead of screws. These are easier but less secure. For off-road use, drilling is recommended. Adhesive-only kits may fail on rough terrain.
Will extensions affect my truck’s warranty?
Aftermarket parts generally do not void the vehicle warranty. However, if you damage something during installation, that repair is your responsibility. Drilling into the fender is considered a modification.
How do I clean mud from behind the extensions?
Use a pressure washer with a narrow tip. Spray from the inside of the wheel well. You can also remove the extensions periodically for a deep clean.
