Description Part Number: 15-06691 The Peterbilt 15-06691 Front Hood Quarter Fender Mudflap is a heavy-duty splash guard made to protect the most vulnerable forward areas of your truck (the front hood quarter fenders) from road debris, dirt spray, gravel, water and other elements encountered every day on the road. This mudflap is a high-quality OEM replacement part built to withstand commercial-grade use and tough driving environments. Compatibility While designed specifically for Peterbilt trucks, this mudflap is built to meet OEM fitment standards and replaces factory-style quarter fender mudflaps on compatible models. Because it uses the manufacturer part number 15-06691, it’s ideal for trucks that require a direct-replacement splash guard without modification. This part can be listed under generic PACCAR or Peterbilt-all makes fitment, indicating it may fit a range of Peterbilt trucks used in vocational, highway and fleet service. If you need this part for another truck brand (like Kenworth, Freightliner, or International), check your OEM specs — most front quarter mudflaps are model-specific and may not interchange without adapters or brackets. Contact Us Material & Construction Benefits The 15-06691 mudflap is made from heavy-duty molded rubber, a material that offers several advantages: Impact resistance: Rubber absorbs hits from stones, sand, and road debris better than rigid plastics, lowering the chance of cracking or splitting. Flexibility in cold or hot climates: Different from thin, stiff options, quality rubber stays flexible in low temperatures and resists heat-induced warping. Durability: Rubber naturally resists abrasion and wear, helping these mudflaps stay effective even after thousands of miles. Easy to clean: Rubber won’t trap dirt like carpeted or fabric styles, and a quick wash with water and soap keeps them looking sharp. The classic black finish also contributes to a professional, clean look while blending with most truck paint schemes. Dimensions & Application According to specifications from parts distributors, the 15-06691 mudflap measures approximately: Length: ~18.0 in Width: ~14.0 in Height (thickness): ~2.0 in Weight: ~2.6 lb (per mudflap) These dimensions make it ideal for covering the front hood-quarter area, often overlooked but vulnerable to road spray and debris. Unlike broader rear mudflaps, this quarter-fender flap provides targeted protection where body damage can occur from grit kicked up by front tires. Installation Tips The 15-06691 mudflap is designed for straightforward bolt-on installation. While specific mounting hardware may vary by truck model and body style: Locate factory quarter fender mounting points or use existing brackets. Align the mudflap so it hangs straight down behind the wheel spray path. Use appropriate fasteners (bolts, clips, or brackets) to secure the flap. Verify there is proper clearance between the mudflap and tire throughout wheel travel. Always consult your truck’s service manual or an experienced technician for exact instructions if mounting locations are unclear. Caring for Your Mudflap To ensure long life from your mudflap: Periodically inspect fasteners – vibration can loosen bolts over time. Wash regularly – removing road salts, oil, and grime prevents premature wear. Check for cracks, tears, or warping after severe storms or off-road use. Proper maintenance keeps mudflaps performing their protective role and prevents flap dragging or excessive wear.
