Frequently Asked Questions About Peterbilt 359 Door Accessories
Will these door handles and latches fit my specific year Peterbilt 359?
Most of our Peterbilt 359 door accessories are designed to fit models from 1967 through 1987, which covers the entire production run. However, there were minor changes between early models (1967-1980) and later models (1981-1987), particularly in latch mechanisms and handle mounting points. We recommend checking your OEM or contacting our support team with your truck's year and door style (standard or extended cab) to ensure proper fitment. Items marked as "universal fit" typically work across all years with minor adjustments.
What's the difference between chrome-plated and stainless steel door accessories?
Chrome-plated accessories offer a mirror-like finish at a lower price point but require regular polishing and may show pitting or rust after 3-5 years, especially in harsh climates. Stainless steel options cost approximately 30-40% more but resist corrosion better and maintain their appearance with minimal maintenance. For trucks exposed to road salt or coastal conditions, we strongly recommend stainless steel. Both options use the same mounting hardware and installation process.
Can I install these door accessories myself, or do I need professional help?
Most door handle and latch replacements can be completed in 1-2 hours per door with basic hand tools including screwdrivers, socket sets, and drill bits. The main challenges include aligning the latch mechanism with the door striker and ensuring proper clearance for smooth operation. Window cranks and interior door panels are typically straightforward 30-minute installations. We provide detailed installation guides with each product, though professional installation may be worthwhile for complete door restoration projects or if you're replacing weatherstripping simultaneously.
Why are some door handles listed as "left" or "right" specific?
Peterbilt 359 exterior door handles are indeed side-specific due to the latch mechanism orientation and the angle of the handle grip. Installing a left handle on the right door will result in awkward operation and potential latch failure. Interior handles are typically universal. When ordering, "left" and "right" are determined as if you're sitting in the driver's seat. If you're unsure, compare the part number on your existing handle or send us a photo of your current setup.
What should I check before ordering replacement door seals and weatherstripping?
First, measure your door gap clearance - factory specs call for 1/4" to 3/8" gap around the door perimeter. Worn door hinges can cause sagging, requiring hinge replacement before new seals will work properly. Check if you have the standard one-piece door seal or the two-piece system (separate cab and door seals). Also verify if your truck has vent windows, as this affects the upper corner seal configuration. Order 10-15% extra length for door seals to account for stretching during installation in cold weather.
