Kenworth Cabover Mud Flaps

Frequently Asked Questions About Kenworth Cabover Mud Flaps

Will these mud flaps fit my specific Kenworth cabover model and year?

Our Kenworth cabover mud flaps are designed to fit K100, K100E, and W900A models from 1963 through 1990. Most of our mud flaps use universal mounting brackets that work with standard fender configurations. However, trucks with custom fenders or non-standard modifications may require additional brackets or drilling. We recommend checking your specific fender measurements against our product dimensions, which are listed on each product page.

What's the difference between rubber and stainless steel mud flaps, and which should I choose?

Rubber mud flaps are more affordable, flexible, and provide excellent spray protection. They typically last 2-3 years with regular use and are easier to replace. Stainless steel mud flaps offer superior durability, lasting 5-10 years or more, and maintain their appearance better in harsh conditions. They're ideal for show trucks or drivers who want a premium look. Consider rubber for cost-effectiveness and function, or stainless for longevity and appearance.

How difficult is the installation, and what tools will I need?

Installation typically takes 30-45 minutes per side for someone with basic mechanical skills. You'll need a drill with metal bits (usually 3/8" and 1/2"), a socket wrench set, and possibly a rivet gun if using heavy-duty brackets. Most mud flaps come with mounting hardware, but some installations may require purchasing additional brackets separately. The biggest challenge is usually accessing tight spaces behind the wheels and ensuring proper alignment to prevent tire rubbing.

What size mud flaps do I need for my Kenworth cabover?

Standard Kenworth cabover mud flaps are typically 24" wide by 30" or 36" long, depending on your tire size and fender configuration. For single rear axles, 24" x 30" usually provides adequate coverage. Trucks with larger tires or those hauling in extreme conditions often benefit from 24" x 36" flaps. Measure from your fender mounting point to 3-4 inches above ground level when loaded to determine the ideal length for your application.

How do I prevent mud flaps from cracking or tearing at the mounting points?

The most common failure point is where the brackets attach to the mud flap. To prevent damage, use anti-sail brackets on longer flaps to reduce wind flutter, ensure mounting bolts aren't overtightened (which can cause stress cracks), and check that flaps have at least 6 inches of clearance from tires when turning. Consider reinforced top sections or adding backing plates to distribute mounting stress. Regular inspection and tightening of hardware every few months will significantly extend mud flap life.
