Frequently Asked Questions About Peterbilt 375/377 Dash Accessories

What model years are these dash accessories compatible with?

Our Peterbilt 375/377 dash accessories are designed to fit models from 1987 through 2007. The 375 and 377 models share the same dash configuration during these production years. However, minor variations may exist between early models (1987-1999) and later models (2000-2007), particularly in mounting hole locations and bezel sizes. We recommend verifying your specific year and VIN with our customer service team if you have a transitional year model.

Are these dash accessories made from genuine chrome or chrome-plated plastic?

Most of our dash accessories feature a combination of materials depending on the specific part. Gauge bezels and switch plates are typically made from heavy-duty ABS plastic with triple-chrome plating for durability and cost-effectiveness. Knobs and smaller accent pieces often use die-cast zinc with chrome plating for added weight and premium feel. Each product listing specifies the exact material composition. All chrome plating meets or exceeds OEM standards for thickness and adhesion.

How difficult is the installation process, and what tools are required?

Installation difficulty varies by accessory type. Most dash panels and bezels can be installed in 30-60 minutes using basic hand tools including Phillips and flathead screwdrivers, trim removal tools, and a 7mm socket. Air brake knobs and shifter accessories typically install in under 10 minutes with no tools required. Complete dash panel replacements may require removing the steering column shroud and disconnecting gauges, which can take 2-3 hours. Detailed installation instructions are included with each product.

Will aftermarket gauges fit in your dash bezels and panels?

Our dash bezels and panels are designed to accommodate standard 2-1/16 inch (52mm) aftermarket gauges, which includes most popular brands like Auto Meter, VDO, and Stewart Warner. The mounting depth allows for gauges up to 3 inches deep. For non-standard gauge sizes or digital displays, custom modification may be required. Our bezels include mounting tabs that work with both mechanical and electronic gauge types.

What finish options are available, and how do they hold up over time?

We offer three primary finishes: polished chrome, brushed aluminum, and matte black. Chrome finishes include a clear protective coating to prevent tarnishing and typically maintain their appearance for 5-7 years with regular cleaning. Brushed aluminum pieces are anodized for scratch resistance. Matte black accessories use a powder-coated finish that resists fading and chipping. All finishes are UV-resistant to prevent sun damage common in truck cabs. Regular cleaning with appropriate products will significantly extend the life of any finish.
