Frequently Asked Questions About Kenworth T300-T450 Cab & Related
Will these cab parts fit my specific Kenworth T300, T330, T340, or T370 model year?
Most cab-related parts for Kenworth T300-T450 models are compatible across years 1995-2010, but there are important exceptions. The T300 (1995-2007) shares many parts with the T330/T340 (2003-2010), while the T370 (2007-2010) may have unique components. Always verify fitment by checking your VIN's build date and comparing part numbers. Key changes occurred in 2003 with updated door handles and mirrors, and in 2007 with revised interior panels. Contact our parts specialists with your VIN for guaranteed compatibility.
What's the difference between OEM and aftermarket cab parts, and which should I choose?
OEM parts typically use heavier gauge steel (16-18 gauge) and exact factory mounting points, while quality aftermarket options use similar materials at 30-50% less cost. For critical structural components like door shells or cab corners, OEM ensures perfect fit. For cosmetic items like mirror brackets, bug shields, or interior trim, aftermarket parts from reputable manufacturers like Dynaflex or Valley Chrome work excellently. Most customers report no fitment issues with aftermarket exterior accessories, though some drilling or minor adjustments may be needed for non-OEM door panels.
How difficult is it to install cab accessories like visors, grab handles, or fender guards?
Installation difficulty varies by part. Sun visors and bug deflectors typically mount using existing holes and take 30-60 minutes with basic tools. Grab handles require drilling 2-4 holes but include templates for accuracy - expect 1-2 hours. Fender guards and mud flaps usually bolt directly to existing mounting points. Door seals need careful removal of old weatherstripping and proper adhesive application. Most installations require standard tools: drill with metal bits, socket set, and torque wrench. Professional installation runs $75-150 per hour if you prefer expert help.
What finishes are available, and how do they hold up to weather and road conditions?
Chrome-plated steel remains popular for its mirror finish but requires regular polishing to prevent pitting. Stainless steel costs 20-30% more but resists corrosion without maintenance - ideal for salt-belt states. Powder-coated options in black or color-matched finishes resist chips better than paint and last 5-7 years typically. Plastic/ABS components should be UV-stabilized to prevent fading. For maximum durability in harsh conditions, choose 304-grade stainless or powder-coated steel over chrome or painted surfaces.
Are there any common fitment issues I should know about before ordering?
The most reported issue involves mirror brackets - pre-2003 models use different mounting spacing than 2003+ versions. Hood-mounted accessories may interfere with certain aftermarket air cleaners. Visor brackets sometimes conflict with CB antenna placement on models with roof fairings. Cab extenders and fairings designed for T300 may need modification for T370 due to slightly different rooflines. Always measure twice: check door opening dimensions for weather seals, verify hood length for bug shields, and confirm mirror arm style (loop vs. straight) before ordering replacements.
