CPOWACE Semi Truck Mud Flaps 24 x 30 in — 4-Pack Heavy-Duty 5mm Polymer Splash Protection

CPOWACE 24 x 30 inch heavy-duty polymer mud flaps provide reliable splash and debris protection for semi trucks and trailers in a durable 4-piece set.

These aftermarket mud flaps are molded from tough polymer and sized to fit most semi-tractor trailers and large trucks. At 24 by 30 inches and 5 mm thick, the set of four offers broad coverage behind wheels to reduce road spray, flying rocks, and road grime that can affect following vehicles and underbody components. The design focuses on straightforward installation and long-lasting weather resistance without adding excessive weight.

How do these mud flaps improve safety for larger vehicles?

Mounted behind the drive and trailer axles, these mud flaps limit water and debris kicked up from tires, improving visibility for drivers behind you and reducing the chance of damage to other road users and your trailer. They act as a physical barrier that catches or deflects spray and small projectiles before they travel rearward.

• 24" x 30" coverage to block broad spray paths from large tires
• 5 mm polymer thickness resists tearing from stones and road debris
• Four-piece set ensures both tractor and trailer can be protected
• Reduces cleanup and wear on trailer undersides and lights

Will these mud flaps fit my semi truck or trailer?

The CPOWACE mud flaps are designed as a universal aftermarket option for most semi trucks, trailers, and heavy-duty rigs. Their 24 x 30 inch dimensions are a common industry size, making them suitable for many standard mounting locations, though some vehicles may require trimming or specific mounting hardware depending on the bracket layout.

• Standard 24" x 30" dimensions fit most common applications
• Flexible polymer allows minor adjustments for irregular mounting points
• Four flaps let you cover dual-axle and trailer setups simultaneously
• Contact seller for fitment questions or custom guidance

How durable and weather-resistant are these polymer mud flaps?

Manufactured from heavy-duty polymer at 5 mm thickness, they resist cracking, tearing, and deformation in typical highway conditions. The material is chosen to withstand frequent exposure to water, salt, oil, and varying temperatures without becoming brittle or sagging.

• Heavy-duty polymer construction for impact and abrasion resistance
• Stable across temperature swings—resists brittleness in cold weather
• Low-maintenance surface repels road grime for easier cleaning
• Designed for long service life under normal commercial use

How simple is installation and what’s included?

Installation is intended to be straightforward: the set ships with four mud flaps sized and ready for mounting, and they can be attached using standard hardware or existing bracket systems. No specialized tools are required for most installs, though drilling or bracket adapters may be necessary on some vehicles.

• Package includes four 24" x 30" mud flaps, 5 mm thick
• Fits standard mounting brackets; can use common bolts and hardware
• Trim-to-fit if required for custom bracket locations
• Seller support available—contact within 24 hours for questions
