Frequently Asked Questions About Peterbilt 357/378 Visors

Will these visors fit my specific year model Peterbilt 357 or 378?

Our visors are designed to fit Peterbilt 357 models from 1987-2002 and Peterbilt 378 models from 1986-2007. However, some mid-year production changes may affect fitment. We recommend checking your existing visor mounting hole pattern or contacting us with your VIN to confirm compatibility. Most visors use the standard 5-hole mounting pattern, but some late-model trucks may have variations.

What material options are available and which holds up best against sun fading?

We offer visors in fiberglass, ABS plastic, and stainless steel. Fiberglass visors are the most popular and provide good durability at an affordable price point. For maximum UV resistance and longevity, stainless steel visors are the premium choice and won't fade or crack. ABS plastic visors are lightweight and economical but may show fading after 3-5 years of sun exposure. All painted visors include UV-resistant clear coat, but stainless options require no maintenance.

Can I install these visors myself or do I need professional help?

Most customers successfully install these visors themselves with basic tools. You'll need a drill with metal bits, socket set, and approximately 2-3 hours. The visors come with mounting brackets and hardware, but you may need to drill new holes if upgrading from a different style. Having a helper makes alignment easier. Professional installation typically runs $150-300 if you prefer to have a shop handle it.

What's the difference between drop visors and standard visors?

Standard visors extend straight out from the cab about 9-13 inches. Drop visors include a downward curve that extends an additional 5-7 inches below the windshield line, providing more sun blockage for drivers in southern climates or those who are shorter in stature. Drop visors may slightly reduce forward visibility at traffic lights, so consider your typical driving conditions when choosing.

Do these visors come with lights or wiring, and are they DOT compliant?

Most visors come pre-drilled for standard 2-inch LED marker lights but do not include the lights or wiring - these are sold separately. You'll need 3-5 amber LED lights depending on visor width. All our visors meet DOT requirements when properly equipped with amber marker lights. We offer complete light kits with plug-and-play wiring harnesses that connect to your existing cab marker light circuit for easy installation.
