Will these door and cab accessories fit my specific Peterbilt 330, 335, or 337 model year?
Most of our door and cab side accessories are designed to fit Peterbilt 330, 335, and 337 models from 2005 to current production years. However, there were minor design changes in 2008 and 2014 that may affect fitment of certain items like door panels and window trim. We recommend checking the specific product description for year compatibility or contacting our support team with your OEM number to ensure proper fitment before ordering.
What's the difference between stainless steel and chrome-plated accessories, and which holds up better?
Stainless steel accessories are made from solid 304-grade stainless and maintain their appearance with minimal maintenance, making them ideal for harsh weather conditions and road salt exposure. Chrome-plated accessories offer a brighter, mirror-like finish but require more frequent polishing and may show pitting over time in corrosive environments. For trucks operating in northern climates or coastal areas, we typically recommend stainless steel for its superior longevity.
Do I need to drill holes or modify my cab to install these accessories?
About 70% of our door and cab accessories use existing factory mounting points or industrial-grade 3M VHB tape for installation, requiring no drilling. Items like door handle covers, mirror brackets, and most trim pieces are designed as direct bolt-on or stick-on applications. However, some accessories like aftermarket grab handles or custom light brackets may require drilling. Each product page clearly indicates installation requirements, and we provide detailed instructions with every order.
Are aftermarket door seals and weather stripping as good as OEM parts?
Our premium door seals and weather stripping are manufactured to meet or exceed OEM specifications, using EPDM rubber compounds that resist UV degradation and maintain flexibility in extreme temperatures. Many customers report better sealing performance than worn OEM parts, particularly with our dual-durometer seals that feature a soft bulb section for sealing and a firm mounting edge. We offer both universal fit and model-specific options, with the model-specific seals providing the most precise fit.
Can I install cab and door accessories myself, or do I need professional help?
Most door and cab accessories can be installed by someone with basic mechanical skills and common hand tools. Simple items like door handle covers, step plates, and trim pieces typically take 15-30 minutes per piece. More complex installations like full door panel replacements or window regulator repairs may take 2-3 hours and benefit from having a second person to help align parts. We provide step-by-step instructions, and our technical support team can walk you through any installation challenges over the phone.
