Frequently Asked Questions About Peterbilt 389 Glider Door Accessories

Will these door accessories fit my specific year Peterbilt 389 glider kit?

Most door accessories in this category are designed to fit Peterbilt 389 glider kits from 2008 onwards. However, there can be slight variations between model years, especially in mounting hole patterns and door panel configurations. We recommend checking the specific product description for year compatibility or contacting our support team with your VIN number to ensure proper fitment. Pre-2008 models may require additional modifications or different part numbers.

What's the difference between OEM and aftermarket door handles, and which should I choose?

OEM door handles are manufactured to exact Peterbilt specifications using original tooling and materials, typically featuring zinc die-cast construction with chrome plating. Aftermarket options often use similar materials but may vary in chrome thickness (usually 0.3-0.5 mil vs OEM's 0.6 mil) and internal mechanism quality. OEM handles generally last 10-15 years under normal use, while quality aftermarket handles average 7-10 years. Choose OEM if you need guaranteed fit and maximum durability; aftermarket works well for budget-conscious buyers who don't mind occasional adjustments during installation.

Do I need special tools or professional installation for door seals and weatherstripping?

Door seal replacement is typically a DIY-friendly job requiring basic hand tools: a trim removal tool, adhesive cleaner, weatherstrip adhesive, and a heat gun or hair dryer. The process takes 2-3 hours per door. Common challenges include removing old adhesive residue and ensuring proper alignment to prevent wind noise. Professional installation runs $150-300 per door but guarantees proper fit. We provide detailed installation guides with our door seals, and many customers successfully complete this job in their driveways.

What causes my glider kit door accessories to wear out faster than expected?

Glider kit doors often experience accelerated wear due to several factors: misalignment from frame modifications during the glider conversion, heavier daily use in commercial applications, and exposure to harsh chemicals during frequent washing. Door hinges and latches are particularly vulnerable if the door isn't properly aligned, causing binding and premature wear. Regular lubrication with white lithium grease every 3 months and checking door alignment annually can double the lifespan of these components. Also, avoid slamming doors and ensure drain holes remain clear to prevent rust.

Are chrome and stainless steel door accessories interchangeable, and how do I match finishes?

While chrome and stainless steel accessories are mechanically interchangeable, mixing finishes creates a mismatched appearance. Chrome has a mirror-like, bluish tint while stainless steel appears more matte with a grayish tone. To match existing accessories, use a white cloth in natural sunlight to compare finishes - chrome will reflect with high clarity while stainless shows a softer reflection. For complete door handle sets, staying consistent with one finish type is crucial. If switching from chrome to stainless, plan to replace all visible door hardware simultaneously for a uniform appearance.
