These MIAOKUI 24" x 24" poly quarter fenders are a heavy-duty, universal bolt-on fender pair for semi trucks that reduce tire spray and resist stone chips.

Built from high-density polyethylene with a matte black finish, this set of two 24" x 24" quarter fenders is designed to fit a wide range of tractors and trailers. The package includes a factory-spec hardware kit—galvanized bolts, reinforced steel brackets, industrial-grade posts, and washers—so installation is straightforward and requires no drilling. These fenders prioritize durability, low maintenance, and a clean factory appearance on Freightliner, Kenworth, Peterbilt and many other rigs.

How do these fenders protect my truck and trailer on the road?

MIAOKUI poly quarter fenders deflect road debris and reduce water and mud spray from your tires, helping preserve paint and undercarriage components. The dense poly material resists cracking from impacts and prevents many stone chips that metal fenders might develop.

• High-density poly reduces stone chip damage and corrosion risk.
• Matte black surface minimizes visible wear and hides dirt.
• Curved shape channels spray away from vehicle body and following traffic.

Will these fenders fit my semi without modification?

The set is made as a universal fit for most semi tractors and trailer axles, designed to bolt on using the supplied hardware. Because the package includes reinforced brackets and adjustable posts, you usually won’t need to drill additional holes—saving time and preserving original mounting points.

• Universal 24" x 24" sizing works with common axle and mud flap layouts.
• Included galvanized bolts and brackets accommodate varied mount positions.
• Bolt-on installation is typically completed in about 10 minutes per fender.

How durable and low-maintenance are these quarter fenders?

Constructed from industrial-grade polyethylene, these fenders withstand road impacts and harsh weather without rusting. They clean easily with water or pressure washing and retain structural integrity through repeated use, reducing upkeep and replacement frequency.

• Poly material resists corrosion, dents, and UV-related cracking.
• Smooth matte finish wipes clean quickly and hides grime.
• Reinforced hardware minimizes loosening from vibration on long hauls.

How fast is installation and what hardware is included?

Each pair comes with a factory-spec hardware kit so you can install the fenders without buying extra parts. Typical bolt-on fitting takes minutes per fender, and the reinforced components are sized to ensure a tight, rattle-free fit on most rigs.

• Reinforced steel brackets for secure mounting.
• Galvanized bolts, industrial-grade posts, and washers included.
• No additional drilling required for most configurations.

Who is this for: These MIAOKUI poly quarter fenders are ideal for owner-operators, fleet managers, and maintenance teams seeking a rugged, low-maintenance replacement or upgrade. They suit drivers of Freightliner, Kenworth, Peterbilt and similar tractors who want a quick bolt-on solution that minimizes spray, resists road damage, and simplifies cleaning between runs.
