Frequently Asked Questions About Kenworth W900B/W900L Door Accessories
What's the difference between W900B and W900L door accessories, and will they fit my truck?
The main difference is the hood length - W900B has a shorter 119" BBC hood while W900L has the extended 130" BBC hood. Most door accessories like handles, mirrors, and window regulators are interchangeable between both models from 1987-2010. However, always verify your specific year as pre-1987 models may have different mounting points. Check your door tag or VIN to confirm your exact model before ordering.
Are aftermarket door handles as durable as OEM parts?
Quality varies significantly by manufacturer. Premium aftermarket handles from brands like Grand General and United Pacific use heavy-duty zinc alloy or stainless steel construction that often exceeds OEM durability. Look for handles with metal internal mechanisms rather than plastic components. Avoid the cheapest options as they typically use pot metal that corrodes quickly. Expect to pay $40-80 for a quality handle that will last.
How difficult is it to replace door seals, and what tools do I need?
Door seal replacement is a moderate DIY job taking 2-3 hours per door. You'll need a heat gun or hair dryer, adhesive remover, weatherstrip adhesive, and basic hand tools. The trickiest part is removing old adhesive completely - use Goo Gone or similar products. Install new seals starting at the top center and work your way around, stretching slightly as you go. Temperature should be above 60?F for proper adhesive bonding.
Which mirror styles work best for W900B/W900L trucks?
West Coast style mirrors are most popular for their classic look and excellent visibility. Hood-mounted mirrors work well for W900B models, while door-mounted setups are preferred on W900L trucks due to the longer hood. Heated mirrors are highly recommended for cold climate operation. Stainless steel mirrors resist corrosion better than chrome-plated versions but cost 20-30% more. Ensure you order the correct arm length - typically 20" for standard applications.
Do I need special wiring when upgrading to power windows or locks?
Yes, you'll need a complete wiring harness kit specifically designed for W900 models. Universal kits often have clearance issues with the door panels. Quality conversion kits include motors, switches, regulators, and pre-terminated wiring harnesses. Installation requires drilling holes for switches and routing wires through existing grommets. Budget 4-6 hours for a complete power window conversion. Professional installation typically runs $300-500 if you're not comfortable with electrical work.
