Freightliner FLD SBA Mud Flaps

Frequently Asked Questions About Freightliner FLD SBA Mud Flaps

Will these mud flaps fit my specific year and model Freightliner FLD?

These mud flaps are designed specifically for Freightliner FLD models with set-back axle (SBA) configurations, typically found on FLD112 and FLD120 models from 1989-2007. The critical measurement is the distance between your rear axle and the back of the cab. For SBA models, this distance is typically 54-62 inches. We recommend measuring your truck before ordering or calling our technical support team with your OEM for exact fitment verification.

What material are these mud flaps made from, and how long will they last?

Our Freightliner FLD SBA mud flaps are constructed from heavy-duty rubber compounds ranging from 3/8" to 1/2" thickness, depending on the specific product. The premium options feature anti-sail ribbing and UV-resistant materials that typically last 3-5 years under normal highway conditions. For severe service applications or frequent off-road use, expect 2-3 years of service life. All materials meet DOT requirements for tear strength and flexibility in temperatures from -40F to 180F.

Do I need special brackets or hardware for installation?

Most installations require mud flap hangers or brackets specific to your frame rail width and configuration. Standard FLD SBA applications typically use either spring-loaded hangers or fixed L-brackets. The mounting hardware is usually sold separately unless specified in the product description. You'll need 1/2" or 5/8" bolts (depending on your existing holes) and basic hand tools. Installation typically takes 30-45 minutes per side for someone with basic mechanical skills.

What styles and sizes are available for FLD SBA applications?

We offer mud flaps in standard 24" x 30" and heavy-duty 24" x 36" sizes for FLD SBA configurations. Style options include plain black, anti-sail with horizontal ribs, weighted bottom flaps, and custom logo options including chrome-embossed Freightliner scripts or reflective DOT tape borders. Quarter fender mud flaps are also available in 16" x 20" sizes for additional wheel coverage. All styles maintain the required 8-10 inch ground clearance when properly installed.

Why are my mud flaps cracking or tearing prematurely?

Premature wear typically results from three main issues: incorrect mounting height (flaps should hang 8-10 inches from ground), using rigid mounting without spring hangers (which causes stress cracks), or purchasing economy-grade flaps not suited for your application. For dump trucks or heavy haulers, always choose reinforced or belted mud flaps. Ensure your hangers allow proper flex movement and check that the flaps aren't making contact with tires during turns or suspension compression.
