Frequently Asked Questions About Peterbilt 379 Day Cab Conversion

What specific Peterbilt 379 model years are compatible with day cab conversion kits?

Day cab conversion kits are designed to fit Peterbilt 379 models from 1987 through 2007. However, there are slight variations between pre-2000 and post-2000 models that affect fitment. Pre-2000 models typically require additional modifications to the rear cab panel, while 2000-2007 models have standardized mounting points that make installation more straightforward. Always verify your specific VIN year with our technical support team before ordering to ensure proper fitment.

What tools and skills are required for a complete day cab conversion installation?

A successful day cab conversion requires intermediate to advanced mechanical skills and specific tools including: a plasma cutter or reciprocating saw for cab modifications, MIG welder for reinforcement brackets, standard metric and SAE socket sets, drill with metal bits, and measuring tools. Most conversions take 16-24 hours of labor. Critical areas include cutting the sleeper section, reinforcing the cab structure, installing new rear window assemblies, and properly sealing all joints. We recommend professional installation if you lack welding experience, as improper structural modifications can compromise cab integrity.

What materials are day cab conversion panels made from, and how durable are they?

Our conversion panels are manufactured from 16-gauge steel with corrosion-resistant primer coating, matching OEM specifications for structural integrity. The window frames use powder-coated aluminum for weight reduction and rust prevention. All weatherstripping is EPDM rubber rated for -40 to 250 degrees Fahrenheit. These materials ensure your conversion withstands commercial trucking demands, with properly installed conversions lasting the lifetime of the truck. Stainless steel hardware is included to prevent rust at connection points.

Will converting to a day cab affect my truck's resale value or DOT compliance?

A professionally executed day cab conversion typically maintains or can increase resale value, as day cabs are often preferred for local and regional hauling operations. However, the conversion must meet DOT requirements including proper rear lighting, reflective tape placement, and structural integrity standards. Document all modifications with photos and receipts. Some states require inspection after major cab modifications - check your local regulations. We provide a conversion completion certificate that helps satisfy inspection requirements.

What finish options are available, and how do they match existing Peterbilt paint?

Conversion panels come in primer finish ready for paint, allowing exact color matching to your truck. We also offer pre-painted options in common Peterbilt colors including Legendary Red, Viper Red, and Arctic White. For custom colors, provide your paint code and we can arrange professional painting before shipping. Chrome and stainless steel accent pieces are available separately to match your existing trim. The primer surface accepts all automotive paint types and provides excellent adhesion when properly prepared.
