Frequently Asked Questions About Sterling A-Series Truck Mud Flaps
Will these mud flaps fit my specific Sterling A-Series model year?
Our Sterling A-Series mud flaps are designed to fit most Sterling trucks manufactured between 1999-2009, including the A9500, AT9500, and L-Line models. However, some modifications may be required for trucks with aftermarket bumpers or custom wheel configurations. We recommend measuring your existing mud flap mounting area before ordering. The standard mounting width is 24 inches for most A-Series models. If you're unsure about fitment, contact our support team with your VIN number for verification.
What's the difference between rubber and polymer mud flaps, and which is better for my Sterling?
Rubber mud flaps are more flexible and perform better in extreme cold conditions, making them ideal for drivers in northern climates. They typically last 2-3 years with regular use. Polymer mud flaps are more rigid, resist cracking and tearing better, and can last 4-5 years. They're excellent for heavy-duty applications and warmer climates but may become brittle in temperatures below -20?F. Both materials meet DOT requirements, so your choice depends on your operating conditions and replacement frequency preferences.
Do I need any special tools or hardware to install these mud flaps?
Installation typically requires basic hand tools including a drill with 3/8" and 1/2" bits, socket wrench set, and possibly a rivet gun if your truck uses riveted brackets. Most of our mud flap kits include stainless steel mounting hardware, but some Sterling models may require additional bracket adapters (sold separately) if converting from OEM plastic flaps to aftermarket heavy-duty options. Installation usually takes 30-45 minutes per side for experienced mechanics.
How do anti-sail mud flaps differ from standard ones, and are they worth the extra cost?
Anti-sail mud flaps feature built-in weights or stiffening ribs that prevent the flap from blowing back at highway speeds, reducing wear and improving spray control. Standard mud flaps can "sail" or flap excessively, especially when empty or bobtailing, which accelerates wear and reduces effectiveness. For Sterling A-Series trucks that frequently run empty or at high speeds, anti-sail flaps can extend lifespan by 40-50% and provide better consistent coverage, making them worth the additional investment.
What width and length mud flaps should I choose for optimal coverage on my Sterling A-Series?
For single rear axle Sterling A-Series trucks, we recommend 24" wide by 30" long mud flaps. Tandem axle configurations typically require 24" wide by 36" long for better coverage. The bottom of the mud flap should hang 6-8 inches from the ground when the truck is loaded. If you frequently haul oversized loads or operate in states with specific splash guard requirements, consider going with the longer 36" option regardless of axle configuration to ensure compliance and maximum protection.
