What's the difference between stainless steel and fiberglass drop visors for my 379?
Stainless steel visors offer superior durability and a classic chrome finish that maintains its shine with minimal maintenance. They're heavier (typically 15-20 lbs) but provide better wind resistance at highway speeds. Fiberglass visors are lighter (8-12 lbs), more affordable, and available in various painted finishes to match your truck. However, they may require occasional repainting and can crack under extreme stress. Most drivers choose stainless for long-term durability or fiberglass for custom color matching.
Will these drop visors fit my specific year Peterbilt 379?
Our drop visors are designed to fit all Peterbilt 379 models from 1987 to 2007. The mounting holes and brackets are identical across these years. However, if your truck has aftermarket modifications to the cab or existing visor mounts, you may need to make minor adjustments. Extended hood models (127" and 131") use the same visors as standard hood models. Always check your existing mounting points before ordering to ensure compatibility.
How difficult is the installation, and what tools do I need?
Installation typically takes 1-2 hours and requires basic tools: a drill with 3/8" and 1/2" bits, socket wrench set, measuring tape, and a level. Most visors come with mounting brackets and hardware. The main challenge is accurately marking and drilling the mounting holes in your cab if they don't already exist. We recommend having a helper to hold the visor in position while marking. Some customers prefer professional installation, which usually costs $100-200 at a truck shop.
What drop length should I choose for my 379?
Drop visors typically come in 5", 7", 9", and 12" drops. The 7" drop is most popular, providing good sun protection without obstructing visibility. If you're under 6 feet tall or have a lower seat position, consider a 5" drop. Taller drivers or those wanting maximum sun blockage often choose 9" or 12" drops. Remember that longer drops may require additional support brackets in windy conditions and can affect your forward visibility when backing up.
Do drop visors affect fuel economy or create wind noise?
A properly installed drop visor typically has minimal impact on fuel economy (less than 1% in most cases) and can actually improve aerodynamics by directing airflow over the cab. However, poorly fitted or loose visors can create significant wind noise and drag. Ensure all mounting bolts are tight and use rubber gaskets between the visor and cab to prevent vibration noise. Some drivers report a slight whistling sound above 65 mph with certain visor designs, which can usually be eliminated by adjusting the mounting angle slightly.
