Tube Fenders

Why use tube fenders

Stock plastic and sheet metal fenders are a weak point on a vehicle that goes off-road with larger tires. They crush against rocks, crack when brushed by trees, and limit the room for wheels to move at full flex. Tube and aluminum fenders replace them with narrower, stronger, or more open designs that offer better tire clearance and a better approach and departure profile. Many owners also like the weight savings of aluminum.

Types of fender parts

• Tube fenders: tubular frames that replace the whole fender and allow a wide opening around the tire.
• Inner fenders: aluminum panels that replace the factory inner fender, often with vents for engine bay airflow and a cleaner way to route wiring.
• Flares and armor: steel or aluminum flares that attach to the body edge with a wider, more rugged look.
• Front and rear sets: separately listed for the front corners and the rear quarter panels, sometimes specific to two-door or four-door models.

Materials and finishes

Aluminum is light and does not rust, though it can dent or tear on hard impacts and is sold bare or with a finish. Steel is stronger and cheaper to repair by welding, but heavier and requires paint or powder coat to prevent corrosion. Thicker plate, such as 3/16 inch steel, adds strength where the part may be hit. Bare metal needs sealing if the vehicle sees salt or coastal air, and anodized or powder-coated finishes last longer in harsh conditions.

What to check before buying

Vehicle fitment is the key detail. Listings often specify a Wrangler generation, number of doors, and whether the part is front or rear, left or right. Check whether the part pairs with other products from the same maker, such as a matching flare. Some kits install with bolts alone, while others need minor drilling or trimming of the factory fender and brackets, and a few need welding. Compare coverage, too, because narrower fenders may not satisfy the rules in your state for covering the tires on the road.

Installation and legal notes

Take your time with test fits and mark any cuts carefully. Seal exposed edges and check that the new fender doesn't interfere with the hood, lights, or steering at full lock. Lighting and turn signals may need relocation. Fender coverage rules vary by state, so check local regulations before using these on public roads. Always confirm fitment for your exact year, make, and model with the manufacturer's specifications.

Maintenance and compatibility

After each trail season, check welds, mounting bolts, and any slotted holes for cracks or loosening, especially near the corners that take the most hits. On bare aluminum, wash off salt and mud, and look for pitting at fasteners where dissimilar metals meet, since steel bolts in aluminum can corrode. Use stainless hardware or anti-seize compound where recommended. Think about the other parts of the vehicle, too. Larger tires, a winch bumper, and body armor can all change which fender style fits well. Keep wiring for turn signals and side markers away from sharp tube edges, and use grommets where cables pass through the panel to prevent chafing.
