Frequently Asked Questions About Kenworth T300-T450 Mirrors & Acc.

Will these mirrors fit my specific Kenworth T300, T350, T400, or T450 model year?

Most aftermarket mirrors for Kenworth T300-T450 models are designed to fit trucks manufactured from 1994 through 2010. However, there can be variations between early and late production years. The T300 and T350 typically share the same mirror mounting points, while T400 and T450 models may have different configurations depending on whether you have a day cab or sleeper. Always check the product description for specific year ranges, and if in doubt, provide your VIN number when contacting us to ensure proper fitment.

Do I need special tools or professional installation for mirror replacement?

Basic mirror replacement typically requires standard hand tools including socket wrenches (usually 13mm-15mm), screwdrivers, and possibly a drill if mounting holes need adjustment. Most mirrors can be installed in 30-60 minutes per side. The main challenges include accessing mounting bolts inside the door panel (you may need to remove the interior door panel) and properly routing any electrical connections for heated or motorized mirrors. While DIY installation is possible, professional installation is recommended for power mirrors to ensure proper wiring and avoid electrical issues.

What's the difference between manual, heated, and motorized mirror options?

Manual mirrors require physical adjustment and are the most affordable option. Heated mirrors include electric heating elements to prevent ice and fog buildup, requiring connection to your truck's electrical system. Motorized mirrors allow adjustment from inside the cab via control switches and often include heating functions. For T300-T450 models, heated mirrors typically draw 3-5 amps per mirror, while motorized versions require a compatible switch panel and may need additional wiring harness adapters if upgrading from manual mirrors.

Are chrome mirrors worth the extra cost over painted black ones?

Chrome mirrors typically cost 30-50% more than painted versions but offer superior corrosion resistance and maintain their appearance longer in harsh conditions. Triple-chrome plated mirrors can last 5-7 years without significant pitting in most climates, while painted mirrors may show wear within 2-3 years. However, painted mirrors are easier to touch up if damaged and better match trucks with blackout packages. Consider your climate, maintenance routine, and aesthetic preferences when choosing.

What mirror accessories are essential for improving visibility on T300-T450 trucks?

The most valuable visibility upgrades include convex spot mirrors (2-4 inch diameter) for eliminating blind spots, especially on the passenger side. Hood-mounted mirrors are crucial for T400/T450 models with longer hoods to see directly in front of the truck. Mirror brackets and arms should be checked for wear - loose or vibrating mirrors are often caused by worn bracket bushings rather than the mirror itself. Consider adding mirror heat shields in hot climates to reduce mirror housing warpage and LED marker lights for enhanced visibility to other drivers.
