Frequently Asked Questions About Western Star 5700XE Truck Mud Flaps

Will these mud flaps fit my specific year model Western Star 5700XE?

Our Western Star 5700XE mud flaps are designed to fit 2016 and newer models. However, slight variations can exist between model years, particularly in mounting bracket locations. We recommend checking your truck's specific mounting points before ordering. If you're unsure about compatibility, contact our support team with your VIN number and we'll verify the correct fitment for your exact truck configuration.

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

Rubber mud flaps are more flexible, cost-effective, and ideal for standard highway driving. They typically last 2-3 years with regular use. Stainless steel backed mud flaps offer superior durability and maintain their shape better in extreme weather conditions, making them perfect for heavy-duty applications or frequent off-road use. The stainless backing prevents sagging and extends lifespan to 5+ years, though they cost approximately 40-60% more than standard rubber options.

Can I install these mud flaps myself, or do I need professional installation?

Most drivers can complete the installation in 30-45 minutes per side with basic hand tools. You'll need a drill with metal bits, socket wrenches, and the included mounting hardware. The main challenge is ensuring proper clearance from the tires - maintain at least 6-8 inches of space to prevent rubbing during turns or suspension compression. Some models may require minor drilling for bracket alignment. We provide detailed installation instructions with each purchase.

How do anti-sail mud flaps perform compared to standard weighted flaps?

Anti-sail mud flaps use aerodynamic design features or internal weights to minimize flapping at highway speeds, reducing wear and improving appearance. Standard weighted flaps rely solely on bottom weights to maintain position. Anti-sail designs typically last 30-40% longer and provide better spray control above 55 mph. They're especially beneficial for long-haul drivers who spend significant time at interstate speeds.

What size mud flaps do I need for my Western Star 5700XE?

Standard Western Star 5700XE trucks typically use 24" wide x 30" or 36" long mud flaps, depending on your tire size and local regulations. Trucks with oversized tires or lift modifications may require longer flaps to meet DOT requirements. Most states require mud flaps to be within 8-10 inches of the ground when the truck is loaded. Measure from your mounting point to determine the appropriate length, keeping in mind that longer flaps provide better protection but may be more prone to damage from steep driveways or off-road obstacles.
