Peterbilt 357/378 Dash Acc.

Frequently Asked Questions About Peterbilt 357/378 Dash Accessories

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

Most of our dash accessories are designed to fit Peterbilt 357 models from 1987-2007 and Peterbilt 378 models from 1986-2007. However, there can be variations between early and late production years. We recommend checking the product description for specific year ranges, or contact our support team with your VIN number to confirm compatibility. Note that some accessories may require minor modifications for trucks with factory-installed options like sleeper configurations or specialized dash layouts.

Are these dash panels and trim pieces made from ABS plastic or metal, and how durable are they?

Our dash accessories come in various materials depending on the specific product. Most dash panels and gauge bezels are made from high-grade ABS plastic that resists cracking and fading better than factory materials. Switch panels and mounting brackets are typically constructed from stainless steel or aluminum. All materials are tested for heat resistance up to 180?F and UV stability. For maximum durability in extreme conditions, we recommend our stainless steel options, though they do come at a higher price point.

Do I need special tools or professional installation for dash accessories?

Most dash accessories can be installed with basic hand tools including screwdrivers, socket sets, and trim removal tools. Installation typically takes 1-3 hours depending on the complexity. Common challenges include removing old adhesive from factory pieces and routing wires for illuminated accessories. We include detailed instructions with each product, and many items use existing mounting points to avoid drilling. For gauge panels and complete dash kits, we recommend disconnecting the battery and having a wiring diagram handy.

What finish options are available, and which matches the factory interior best?

We offer multiple finish options including chrome, brushed aluminum, powder-coated black, and woodgrain patterns. For matching factory interiors, most 1990s-early 2000s models came with either gray or tan plastic, which our standard ABS options match well. Chrome and brushed finishes are popular upgrades that complement any interior. If you're unsure about color matching, we recommend ordering color samples first, as monitor displays can vary. Custom paint-matching services are also available for exact OEM color reproduction.

Can I return or exchange dash accessories if they don't fit properly?

Yes, we accept returns on dash accessories within 30 days of purchase if they're in original condition with all packaging. However, custom-ordered items, electrical components that have been installed, and clearance items are final sale. We strongly recommend test-fitting all pieces before final installation. If you receive a defective item or the wrong part, we'll cover return shipping. For fitment issues, our technical support team can often provide installation tips or identify if you need a different part number for your specific truck configuration.
