Frequently Asked Questions About Peterbilt 375/377 Day Cab Conversion

Will these day cab conversion kits fit my specific year model Peterbilt 375 or 377?

Our day cab conversion kits are designed to fit Peterbilt 375 and 377 models from 1987 through 2007. However, there are minor variations between early models (1987-1999) and later models (2000-2007) that may affect fitment of certain components. We recommend checking your VIN and contacting our support team to confirm compatibility with your specific truck before ordering. Most conversion kits will require minimal modifications for trucks with factory sleeper configurations.

What tools and skills are required for installation?

Installing a day cab conversion typically requires intermediate mechanical skills and access to standard shop tools including a welder, grinder, drill, and basic hand tools. The process involves removing the sleeper unit, cutting and preparing the cab back wall, installing new panels, and sealing all connections. Most installations take 8-12 hours for experienced mechanics. Professional installation is recommended if you're not comfortable with bodywork and welding. Detailed installation instructions are included with each kit.

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

Our conversion panels are manufactured from 16-gauge steel or aluminum, depending on the specific kit you choose. Steel panels come with a primer coating and require painting to match your truck. Aluminum panels offer superior corrosion resistance but may require special welding techniques. Both materials are designed to match OEM specifications for strength and longevity. All kits include weather stripping and sealing materials to ensure a watertight installation.

Do I need to modify my exhaust system after converting to a day cab?

Yes, most conversions will require exhaust modifications since the factory sleeper configuration typically routes exhaust stacks differently than a day cab setup. You'll need to relocate or shorten your exhaust stacks to clear the new cab profile. We offer exhaust relocation brackets and shortened stack options specifically designed for 375/377 conversions. The exact modifications needed depend on your current exhaust configuration and desired final appearance.

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

A professionally installed day cab conversion can actually increase resale value for buyers seeking day cab configurations, as factory day cab 375/377 models are less common. However, documentation of the conversion is important for resale. Regarding DOT compliance, the conversion itself doesn't affect regulations, but you must ensure all lights, reflectors, and safety equipment meet current DOT standards after modification. We include DOT-compliant marker lights and reflectors with our complete conversion kits.
