Kenworth T880 Mud Flaps

Frequently Asked Questions About Kenworth T880 Mud Flaps

Will these mud flaps fit my specific year and configuration of Kenworth T880?

Most aftermarket mud flaps for the T880 are designed to fit models from 2013 to present. However, fitment can vary based on your truck's configuration - particularly if you have a dump truck, mixer, or vocational setup versus a standard highway tractor. Check the product description for specific year ranges and measure your existing mounting brackets. Standard mounting widths are typically 24" or 30", but custom applications may require different sizes. If you're unsure, contact us with your OEM and we can verify compatibility.

What's the difference between rubber, poly, and stainless steel backed mud flaps?

Rubber mud flaps are the most economical option and work well for standard highway use, typically lasting 1-2 years. Heavy-duty poly mud flaps resist cracking in cold weather and last 2-3 times longer than rubber, making them ideal for construction and off-road applications. Stainless steel backed options provide maximum durability and a premium appearance but are heavier and more expensive. For T880s used in vocational applications, we typically recommend anti-sail poly flaps with reinforcement ribs to prevent wind flutter at highway speeds.

Do I need special brackets or hardware to install these mud flaps?

Installation requirements depend on your current setup. If you're replacing existing mud flaps, you can often reuse your current brackets and hardware. For new installations, you'll need mud flap hangers (sold separately) that match your frame rail spacing. Most T880s use standard 2.5" spring-loaded hangers or adjustable angle brackets. Installation typically takes 30-45 minutes per side with basic hand tools. Some heavy-duty applications may require drilling, so check if the product includes a template.

How do I prevent mud flaps from breaking off in reverse or catching on obstacles?

The most common cause of mud flap damage on T880s is improper height adjustment. Your mud flaps should hang 6-8 inches from the ground when loaded. For trucks that frequently back over curbs or rough terrain, consider anti-sail flaps with tapered edges or adjustable hangers that allow quick height changes. Spring-loaded hangers also help by allowing the flap to flex backward. Avoid rigid mounting systems if you do frequent backing maneuvers.

Are weighted or standard mud flaps better for my T880?

Weighted mud flaps (typically 3-5 lbs per flap) hang straighter and reduce wind sail, making them ideal for highway driving and reducing spray on following vehicles. They're especially beneficial for T880s pulling flatbeds or in windy conditions. However, standard non-weighted flaps are better for vocational trucks that encounter obstacles, as they're less likely to cause damage when they make contact. Consider your primary use - highway hauling typically benefits from weighted, while construction and off-road applications often work better with standard flaps.
