MIAOKUI 24" x 24" Poly Quarter Fenders Set of 2 - Universal Heavy-Duty Black with Mounting Posts

MIAOKUI 24"x24" poly quarter fenders are a pair of universal, heavy-duty black fenders with mounting posts designed to protect semi trucks and trailers from road debris and spray.

These MIAOKUI quarter fenders are molded from high-density poly for durability and a matte-black finish that resists stone chips and reduces spray. Sold as a set of two 24" x 24" sections, they include a factory-spec hardware kit with galvanized bolts, reinforced steel brackets, industrial-grade posts, and washers so you can bolt them on quickly without drilling. The design aims to lower maintenance while delivering a snug fit across common makes like Freightliner, Kenworth, and Peterbilt.

How do these quarter fenders protect my truck on the road?

The poly construction absorbs impacts from small stones and shields tires from water and debris, cutting down on spray and grime. Their matte finish hides scuffs and reduces visible stone chips, helping your rig look cleaner between washes.

• High-density poly resists cracking and chipping.
• Molded shape deflects road spray away from trailer and cab.
• Matte black finish minimizes visible wear and keeps appearance neat.

Will these fenders fit my semi truck or trailer?

They are manufactured as a universal 24" x 24" quarter fender set meant to mount on most common semi and trailer applications. The kit includes reinforced steel brackets and adjustable posts, so the pieces adapt to a broad range of axle and frame configurations without custom cutting.

• Universal bolt-on design for many Freightliner, Kenworth, and Peterbilt models.
• Included steel posts and brackets for secure attachment.
• No drilling required for most standard installations.

How long does installation take and what tools are necessary?

With the factory-spec hardware included, most installs take roughly ten minutes per fender when mounting to compatible frames. Basic hand tools—ratchet, wrenches, and alignment tools—are typically all that’s needed; no specialized fabrication required.

• Complete hardware kit supplied: bolts, washers, brackets, posts.
• Estimated install time: about 10 minutes per fender on standard setups.
• No drilling for most applications; bolts secure directly to existing mounts.

What maintenance is required to keep these fenders performing?

Maintenance is minimal: periodic rinsing and an occasional wipe-down keep the matte finish clean and free of buildup. The poly material does not corrode and the galvanized hardware resists rust, lowering long-term upkeep compared with metal alternatives.

• Simple rinse or wipe to remove road grime and salt.
• Galvanized bolts and steel brackets reduce corrosion risk.
• Durable poly resists dents and maintains shape under load.

Who is this for: the MIAOKUI 24" x 24" poly quarter fender set suits truck and fleet owners, owner-operators, and service shops who want a rugged, low-maintenance mudguard solution. It’s ideal for drivers of mainstream heavy-duty rigs (Freightliner, Kenworth, Peterbilt) and for trailer owners seeking a quick bolt-on upgrade to reduce spray, protect paint, and minimize routine repairs. If you need a durable, universal mounting option with included hardware and fast installation, this set addresses those needs without complex modifications.
